1.2.2 Safety Precautions
When working with analytical instrumentation, you must know the potential hazards of
using chemical solvents.
Tips: Before operating the monitor for the first time, read this manual once to make
yourself familiar with the contents of this manual
Please also note the information in the related sections and in the Operating
Instructions of the pump and the optical detector.
Warning: All users of the device must observe the following safety precautions
and all additional safety precautions in this manual to avoid the
possibility of personal injury or damage to the device when operating
the device or carrying out any maintenance or service procedures.
Protective equipment
When performing any work on or near the HPLC system, wear personal protective
equipment (protective clothing, safety gloves, safety glasses) as required by the hazard of
the mobile phase and sample. For information about the proper handling of a particular
substance and for advice on specific hazards, refer to the material safety data sheet for the
substance you are using. Observe the guidelines of Good Laboratory Practice (GLP).
An eyewash facility and a sink should be close to the device. If any substance splashes on
the eyes or skin, wash the affected area and seek medical attention.
UltiMate 3000 Series:
pH and Conductivity Monitor PCM-3000
Page 4 Operating Instructions
Hazardous substances
Many organic solvents, mobile phases, and samples are harmful to health. Be sure that
you know the toxic and infectious properties of all substances that you are using. You
may not know the toxic or infectious properties of many substances that you are using. If
you have any doubt about a substance, treat it as if it contains a potentially harmful
substance. For advice on the proper handling of a particular substance, refer to the Safety
Data Sheet (SDS) of the manufacturer. Observe the guidelines of Good Laboratory
Practice (GLP).
Dispose of waste substance in an environmentally safe manner that is consistent with all
local regulations. Do not allow flammable, toxic, and/or infectious substances to
accumulate. Follow a regulated, approved waste disposal program. Never dispose of
flammable, toxic, and/or infectious substances through the municipal sewage system.
Hazardous gases
Install the HPLC system in a well-ventilated laboratory. If the mobile phase or sample
includes volatile or flammable solvents, do not allow them to enter the workspace. If the
mobile phase or sample includes volatile or flammable solvents, avoid open flames and
sparks.
Electrostatic discharge
Discharge of electrostatic energy may lead to sparking and can constitute a fire hazard.
Keep in mind that liquid flowing through capillaries can generate static electricity. This
effect is particularly pronounced in insulating capillaries and with non-conductive
solvents (for example, pure acetonitrile).
Take appropriate measures to prevent the generation of static electricity near the HPLC
system. For example, make sure that the air humidity level in the laboratory is
sufficiently high and provide proper ventilation, wear anti-static clothing or shoes,
prevent accumulation of air bubbles in waste lines, and use grounded waste containers.
Use only non-conductive capillaries to direct solvents into the waste container. With
electrically conductive capillaries, make sure that they are properly grounded.
Self-ignition of solvents
Do not use solvents for which the self-ignition temperature is below 150 °C. In case of
leakage, these solvents may self-ignite on a hot surface.
Capillaries, capillary connections, open connections
Capillaries, especially non-metallic capillaries may burst, slip out of their fittings or
may not be screwed in. This may result in substances spraying out of the open
connections.
In an UltiMate 3000 system, some components are made of PEEK™. This polymer
has superb chemical resistance to most organic solvents. However, it tends to swell
when in contact with trichlormethane (CHCl3), dimethyl sulfoxide (DMSO), or
tetrahydrofuran (THF). In addition, it is attacked by concentrated acids, such as,
sulfuric acid and nitric acid or a mixture of hexane, ethyl acetate, and methanol.
UltiMate 3000 Series:
pH and Conductivity Monitor PCM-3000
Operating Instructions Page 5
In both cases, capillaries may start leaking or they can burst. Swelling or attack by
concentrated acids is not a problem with brief flushing procedures.
Do not use tubing that is stressed, bent, kinked, or damaged.
Capillary connections can be contaminated by harmful substances or harmful
substances can escape from open connections.
In an UltiMate 3000 Bio RS system, some system capillaries are made of MP35N®, a
nickel-cobalt based alloy. Individuals with sensitivity to nickel/cobalt may show an
allergic reaction from skin contact.
Always wear safety glasses when handling fused silica tubing, for example, during
installation or when cutting capillaries to the length.
Be aware that liquid may have been spilled when removing the hood. If a leak occurs,
remedy the situation immediately.
Replace faulty communication cables.
Replace faulty power cords. Never use a power cord other than the power cords provided
for the device.
Use only the original spare parts and accessories authorized for the device by Thermo
Fisher Scientific.
When operating the HPLC system, always set a lower pressure limit for the pump. This
prevents damage resulting from leakage or from running the pump dry.
The module is primed with 2-propanol when being shipped from the factory. Make sure
to flush the device with water or a buffer solution before first use of the pH electrode.
After operation, rinse out buffers and solutions that form peroxides.
Before switching from buffer to organic solution, rinse the analytical system thoroughly
with de-ionized or HPLC grade water.
When switching to another solvent, ensure that the new solvent is miscible with the one
contained in the HPLC system. If the solvents are not miscible, the system can be
damaged, for example, by flocculation.
Use only standard solvents (HPLC grade) and buffers that are compatible with all parts in
the monitor that may be exposed to solvents.
Before interrupting operation for several days or more or when preparing the monitor for
transport, observe the precautions for shutting down the monitor ( page 47).
Do not use the module in ways other than those described in these Operating
Instructions.
Keep the operating instructions near the device to be available for quick reference.

Operating Instructions Page 7
Gaz dangereux
Installez le système HPLC dans un laboratoire bien ventilé. Si la phase mobile ou
l’échantillon contient des solvants volatils ou inflammables, vous devez assurer qu'ils ne
pénètrent dans l'espace de travail. Si la phase mobile ou l’échantillon contient des
solvants volatils ou inflammables, évitez les flammes nues et les sources d’étincelles à
proximité.
Décharge électrostatique
Décharge électrostatique peut provoquer la formation d'étincelles et peut présenter un
risque d’incendie. Veuillez noter que des solvants fluides dans les capillaires peuvent se
charger automatiquement. Cet effet se peut produire particulièrement forte dans les
capillaires isolants et avec des solvants non-conducteurs (par exemple, l'acetonitrile pur).
Prenez des mesures appropriées pour éviter les charges électrostatiques à proximité du
système HPLC. Par exemple, s'assurez qu'il y a une humidité de l'air suffisante et une
ventilation adéquate dans le laboratoire, portez des vêtements ou équipement de
protection antistatique, évitez l'accumulation de bulles d'air dans les lignes de déchets et
utilisez des réservoirs à déchets mis à la terre.

déchets. Capillaires électriquement conducteur devrait être mis à la terre.
Inflammation spontanée des solvants
N’utilisez aucun solvants avec une température d‘auto-inflammabilité inférieure à
150° C. Si une fuite se produit, ces solvants peuvent s’auto-enflammer au contact d’une
surface chaude.
Capillaires, connecteur capillaires, connexions ouvertes
Descapillaires, en particulier les capillaires non-métalliques, pourraient fendre ou
glisser des connecteurs ou ne peuvent pas être vissés. Ceci peut en résulter aussi que
des substances pourraient jaillir des connexions ouvertes.
Dans un système UltiMate 3000, certaines composantes sont en PEEK. Bien que ce
polymère présente une excellente résistance chimique à la plupart des solvants
organiques, il a tendance à gonfler lorsqu'il est en contact prolongé avec du
chloroforme (CHCl3), du diméthyle sulfoxyde (DMSO) ou du tétrahydrofurane
(THF). De plus, il est attaqué par des acides concentrés tels que l'acide sulfurique et
l'acide nitrique ou d'un composé du hexane, éthyle acétate et méthanol. Ceci peut
causer des capillaires de fuite ou risquer des capillaires d’éclater. Ces acides peuvent
cependant être utilisés dans le cadre de procédures de nettoyage, à condition que
l’exposition soit brève.
N'utilisez pas de capillaires écrasés, pliés, abimés ou endommagés.
Les connecteurs capillaires pour pourrait être contaminé par des substances
dangereuses ou des substances dangereuses pourrait sortir des connexions ouvertes.
Dans un système UltiMate 3000 Bio RS, certains capillaires du système Viper sont
faits d'alliage de nickel-cobalt MP35N. Contact avec la peau peut provoquer une
réaction chez les personnes qui sont sensibles au nickel/cobalt.

2 Overview
2.1 Unit Description
The PCM-3000 pH and conductivity monitor is designed as a module for measuring the pH
and conductivity value of liquids in combination with a diode array detector, multiple
wavelength detector, or variable wavelength detector of the UltiMate 3000 series.
A pH electrode is used to monitor - over a period of time - the pH value of a liquid that is
flowing through the pH flow cell.
The pH flow cell is equipped with a temperature sensor. Chromeleon automatically
considers the measured temperature value when calculating the pH value, thus improving
the accuracy of the measurement.
A conductivity flow cell is used to monitor - over a period of time - the conductivity
value of a liquid that is flowing through the flow cell.
The conductivity flow cell is equipped with a temperature sensor. Chromeleon
automatically considers the measured temperature value when calculating the
conductivity value.
Calibration of the conductivity flow cell and pH electrode is easy and can be performed
directly in Chromeleon.
Features for monitoring the calibration are provided in Chromeleon to ensure system
reliability.
UltiMate 3000 Series:
pH and Conductivity Monitor PCM-3000
Page 12 Operating Instructions
2.2 Configurations
The pH and conductivity monitor measures the pH value and conductivity of a flow of
liquid. The measured values are processed by the instrument driver of the detector and can
be viewed in Chromeleon as well as on the detector display. The module is available in the
following configurations:
Description Part no.
PCM-3000 for DAD/MWD detectors of the UltiMate 3000 series. 6082.2000

2.3 pH Flow Cell and pH Electrode
The pH flow cell is pre-installed on the flow cell carrier. A dummy electrode protects the
flow cell from dust. As the temperature of the liquid is required for calculating the pH
value, the pH flow cell is equipped with a temperature sensor, which is connected to the
PCM-3000 extension board on the detector rear panel via a cable. The temperature values
can be monitored in Chromeleon as a separate signal.
Fig. 2: pH flow cell with dummy electrode
The pH electrode shipped with the monitor is placed in the flow cell during pH
measurements. An electrode storage container is mounted on the flow cell carrier for
storing the electrode "offline"; that is, outside of measurements. Before initial operation,
the pH electrode must be calibrated.

2.4 Conductivity Flow Cell
The conductivity flow cell is pre-installed on the flow cell carrier.
An identification chip is fitted to the flow cell in the factory. The chip stores the cell
calibration data, among other information. When the flow cell is connected to the detector
rear panel, the chip is connected to the electronics. It is therefore not mandatory to
calibrate the cell before initial operation. To achieve optimum accuracy with the used
substances, however, calibrating the flow cell is recommended before operation ( page
42).
As the conductivity of a substance is influenced by its temperature, the conductivity flow cell
is equipped with a temperature sensor. The temperature values can be monitored in
Chromeleon as a separate signal. Chromeleon can then perform a temperature compensation
of the conductivity value.
Fig. 3: Conductivity flow cell with connection cable
2.5 Fluid Connections
The capillary connections are premounted at the factory. A recess is provided in the hood
to accommodate the connection from the optical detector to the conductivity flow cell. In
the detector enclosure, the capillary slot on the left can be used for this connection.
The capillary from the pH flow cell to the waste can be guided through another small recess at
the rear of the hood.
