tm

CS micro Gas Chromatograph

GC analysis for virtually any fixed gas and hydrocarbons up to C

for laboratory, at-line,

transportable or online use

CALIDUS Model CS -

comprised of 5 modules

A single Sample Processing Unit with a standard split/splitless injection port (1:1 up to 1:200) suitable gas and liquid

samples via either syringe through the septum injections, optional gas, liquid or headspace auto-sampler, or

automated sampling valves. The inlet includes septum purge to prevent bleed components from entering the system.

The sample is then delivered to a column switching valve for analysis on two independent column modules.

Two Programmed Temperature Column Modules (PTCM) separated by a column switching valve containing the

resistively heated steel capillary chromatography column with necessary hardware, software and electronic control to

enable temperature programming from 0.1

o

C to 5

o

C per second from 5

o

C above ambient to 180

o

C (the maximum

temperature for the valve, higher available on request) depending on the maximum temperature capability of the

column material selected. Each column module is independently controlled by the method and can be any of the

available column types.

Two independent Detector Modules incorporating either a micro Flame Ionization Detector (FID) or micro Thermal

Conductivity Detector (TCD) with the necessary hardware, software and electronic control to provide detector

temperature control, digital output signal and additionally for proper FID fuel supply pressure and auto-ignition.

The micro FID is a fully digital carbon/hydrogen bond detector using the hydrogen flame to burn the sample

components. It uses an electrometer to sense the current changes in the flame cell due to chromatographic

component elution. The data rate is 100 Hz.

The micro TCD is a fully digital, universal detector. The TCD consists of a constant temperature filament that

senses change in power required to hold the filament temperature constant when chromatographic

components elute. The power measurement is used to determine the amount of the component eluting from

the column. The data rate is 50 Hz.

CALIDUS is controlled with ChromPerfect chromatography data system fully integrated with LineUp running on a

Windows PC.

SIGNIFICANCE AND USE

The Model CS provides a simple ultra-fast analysis (10 to 50 times faster than conventional lab or process

GC’s) of fixed gases and hydrocarbons to C

12

. Use of two different PTCMs with their own detectors

separated by the column switching valve with the appropriate column material enables leveraging the

sensitivity and selectivity differences for enhanced separations (for example heartcuts and backflushing).

Proper choice of columns enables wide boiling range and concentration ranges with a single GC. Model CS

is ideal for individual component speciation from other sample matrix components.

The analyses are used for product specifications testing, product safety, environmental measurements,

process control, catalyst protection, educational tools, spot checks of fuels and many more.
