ACALIDUSmicrogas chromatograph features fully-independent ProgrammedTemperature
ColumnModules (PTCM) that canbeoperated isothermallyand interfaced toa Sample
ProcessingUnit (SPU). DetectorModules (DM) arealso fully-independent and canbemixed
andmatchedwithin theCALIDUSSampleProcessingUnit environment.
SPU -
standardwitha split/splitless injectionport (1:1up to1:200) suitable for gasor liquid samples viaa
syringe through the septum injection, optional automated samplingvalves for gasor liquidsor anoptional
auto-sampler capableof liquidor heatedheadspacegas samples. The inlet includes septumpurge toprevent
bleed components fromentering the system.
PTCM -

DM -
incorporatesmicro Flame IonizationDetector (FID) ormicroThermal ConductivityDetector (TCD)with
thenecessaryhardware, softwareandelectronic control toprovidedetector temperature control anddigital
output signal.
o
FID -
fullydigital carbon/hydrogenbonddetectorusing thehydrogen flame toburn the sample
components. Ituses anelectrometer to sense the current changes in the flame cell due to
chromatographic component elution. Control isprovided for the fuel supplypressureandauto-ignition.
Thedata rate is 100Hz.
o
TCD -
fullydigital, universal detector consistingof a constant temperature filament sensing the change in
power required tohold the filament temperature constant due to chromatographic component elution.
Thedata rate is 50Hz.
CALIDUS is controlledwithChromPerfect chromatographydata systemand fully integratedwith LineUp runningona

SIGNIFICANCEANDUSE
TheCALIDUSmicrogas chromatographprovides a simpleultra-fast analysis (10-50 times faster
than conventional labor processGC’s) of fixedgases andhydrocarbonsup toC
50
. CALIDUS is
available for laboratory, at-line, transportableor onlineuse in thehydrocarbonprocessing
industry, environmental labs, pharmaceuticals, foodandbeverage industry,military,medical
industry, andeducationalmarkets.
Theanalyses areused for product specifications testing, product safety, environmental testing
andmeasurements, process control, catalyst protection, educational tools, spot checksof fuels
andmanymore.
