A CALIDUS micro gas chromatograph features fully-independent Programmed Temperature
Column Modules (PTCM) that can be operated isothermally and interfaced to a Sample
Processing Unit (SPU). Detector Modules (DM) are also fully-independent and can be mixed
and matched within the CALIDUS Sample Processing Unit environment.
SPU -
standard with a split/splitless injection port (1:1 up to 1:200) suitable for gas or liquid samples via a
syringe through the septum injection, optional automated sampling valves for gas or liquids or an optional
auto-sampler capable of liquid or heated headspace gas samples. The inlet includes septum purge to prevent
bleed components from entering the system.
PTCM -
resistively heated steel capillary chromatography column with necessary hardware, software and
electronic control for temperature programming from 0.1
o
C to 10
o
C per second from 5
o
C above ambient to
400
o
C depending on the model and maximum temperature capability of the column material selected.
DM -
incorporates micro Flame Ionization Detector (FID) or micro Thermal Conductivity Detector (TCD) with
the necessary hardware, software and electronic control to provide detector temperature control and digital
output signal.
o
FID -
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. Control is provided for the fuel supply pressure and auto-ignition.
The data rate is 100 Hz.
o
TCD -
fully digital, universal detector consisting of a constant temperature filament sensing the change in
power required to hold the filament temperature constant due to chromatographic component elution.
The data rate is 50 Hz.
CALIDUS is controlled with ChromPerfect chromatography data system and fully integrated with LineUp running on a
Windows PC.

SIGNIFICANCE AND USE
The CALIDUS micro gas chromatograph provides a simple ultra-fast analysis (10-50 times faster
than conventional lab or process GC’s) of fixed gases and hydrocarbons up to C
50
. CALIDUS is
available for laboratory, at-line, transportable or online use in the hydrocarbon processing
industry, environmental labs, pharmaceuticals, food and beverage industry, military, medical
industry, and educational markets.
The analyses are used for product specifications testing, product safety, environmental testing
and measurements, process control, catalyst protection, educational tools, spot checks of fuels
and many more.
