The CMS5000 Monitoring System provides online water or air monitoring for the
detection and analysis of VOCs. The programmable sample collection system
allows for on-site, rapid analysis of current air or water conditions without the need
for pre-treatment or filtration.
CMS5000 Operating Manual
Chapter 1
Introduction
Due to U.S. Nuclear Regulatory Commission regulations,
the CMS5000 oven, which contains a sealed radioactive
source, may not be repaired by unauthorized personnel.
INFICON will provide the maintenance, repair,
replacement and disposal of the radioactive source, as
well as any part of the detector.
For water analysis, VOCs are purged from the water flowing through the water
vessel. Argon will bubble into the water, the gas bubbles will rise through the water
and collect at the top of the collection tube. As the bubbles rise, a portion of the
VOCs will pass from the water phase to the gas phase — this is known as
"partitioning". The ratio of the VOC concentration in the water phase, VOC
the concentration in the gas phase, VOC
equation [1].
IPN 074-508-P1C
Each compound will partition according to its solubility in water, its vapor pressure,
the specific water sampling matrix and the temperature. The quantity of VOCs
detected is dependent on the partition coefficient. In general, highly polar
compounds are more readily detected than less polar compounds.
A permeation tube that contains toluene is used as a check standard to ensure
proper system calibration and verify sample integrity. It will compensate for normal
fluctuations in the column, the concentrator and detector sensitivity. The lifetime of
the permeation tube is approximately 8 years.
After collection, the VOCs from the air or water samples are drawn into the
CMS5000 with the internal pump and adsorbed by the concentrator. The VOCs are
then desorbed into the column of the gas chromatograph by heating the
concentrator and reversing the carrier gas flow.

CMS5000 Operating Manual
1.2 Gas Chromatograph
The gas chromatograph (GC) performs a time separation of the sample
compounds. The separation order is primarily based on increasing compound
boiling point.
Argon is used as the carrier gas to transport analytes through a 100%
dimethylpolysiloxane, 0.32 mm id, 30 M, 4.0 µm (or equivalent) column. The inside
of the column is coated with a thin layer of material known as the stationary phase.
The stationary phase selectively attracts components in a sample mixture. The
mixture of sample compounds in the argon gas, also known as the mobile phase,
interact with the chemicals of the stationary phase. The chemicals which spend the
least time partitioned in the column will elute (exit) off the column first.
The time taken by an individual compound to travel into the system until the
compound elutes from the column is referred to as the retention time (RT). If the
GC conditions remain constant, the same compound will elute from the column at
nearly the same retention time for each injection.
The performance of the column is affected by temperature, therefore, the column
is housed in a temperature controlled oven. The oven is programmed to increase
the temperature gradually (called ramping) to improve compound separation while
decreasing analysis time. As the temperature increases, the compounds with the
lowest boiling points will elute first with the standard non-polar phase coated
column installed.
A chromatogram of eluting organic gases from the gas chromatograph is plotted as
a function of time from the injection the compound mixture. The chromatogram
depicts the separation of the various compounds from each other by the action of
the gas chromatograph, as described above.
1.3 Micro Argon Ionization Detector (MAID)
The Micro Argon Ionization Detector (MAID) is sensitive to organic compounds
having an ionization potential of 11.7 eV or lower, which includes halomethanes,
haloethanes, carbon tetrachloride and 1,1,1-trichloroethane. The CMS5000 can
detect these compounds, as well as other hydrocarbons, to parts-per trillion (PPT)
levels.
The MAID uses argon as a carrier gas. When argon flows over a nickel-63 (Ni-63)
source, argon atoms are energized to an excited, metastable state, while other
argon atoms are ionized. The excitation energy of argon is approximately 11.7 eV.

IPN 074-508-P1C

When an organic molecule (R) enters the detector, it collides with the metastable
WARNING
argon (Ar*). During this collision, energy is released to the organic molecule. Since
the ionization potential of most organic compounds is less than 11.7 eV, the
metastable argon atoms will ionize them, producing positive ions and electrons.
The reaction is illustrated as follows:
Ar* + R
Ar + R + e
High voltage applied across the detector produces a current, which is amplified and
measured to produce a chromatogram.
1.4 Radioactive Source
The MAID in the CMS5000 contains a radioactive isotope in a solid form of Ni-63,
with an activity level of up to 2.4 millicuries. The half-life of Ni-63 is approximately
96 years. The source of the radioactivity is sealed within a stainless steel cylinder
which is located within the detector cavity. Per New York State radioactive materials
license regulations, a wipe test is required for the Ni-63 source every 36 months.
The first test is completed at the factory prior to shipment.

No repair of the detector cell should be performed by the
user. If the detector cell does not exhibit an electronic
signal, the isotope may require replacement. Contact
INFICON for repair or replacement of the detector cell.
The State of New York Department of Labor, Division of Safety and Health and the
United States Nuclear Regulatory Commission under either a Specific License or a
General License authorizes possession and use of the radioactive source in the
instrument. A copy of the terms and requirements of a General Licensee (section
12 NYCRR, part 38:41, table 3, item b) accompanied INFICON transfer of this
instrument. The safety requirements of the Specific License or General License are
designed to protect the user and the public from unnecessary prolonged exposure

the filled sampling vessel. The CMS5000 weighs 55.1 lbs. (25 kg). All plumbing to
and from the sampling vessel should be supported independently of the analytical
module, as the system design will not support any additional weight.
For air monitoring, the CMS5000 should be mounted in an optimal location for
collecting air samples of interest. Care should be exercised to avoid locations
affected by air currents from heating or cooling systems, doors, windows or
structural openings.
To ensure proper operation when utilizing the CMS5000 for continuous water
monitoring, it is necessary to determine optimal mounting height and unit
placement to accommodate both the water intake as well as allow for clearance for
the sample collection tube when attaching and removing the sampling vessel.
Allow a minimum of a 15” (38.1 cm) clearance below the mounted sampling vessel
for vessel removal. Verify that the CMS5000 is level when mounted and that the
slope is less than five percent. See Figure 3-2.

3.8 Air Monitoring Assembly Instructions
The CMS5000 easily converts to a continuous Air Monitoring System via two
configurations. The first configuration, designed for ambient air sampling, requires
the user to replace the water collection tube with a air collection tube with attached
filter. The filter at the opening of the collection tube prevents large particulates in
the sampling environment from entering the system.The second configuration is
designed for in-line air sampling. This configuration is more complex.
