A singleDetectorModule incorporatingeither amicro Flame IonizationDetector (FID) ormicroThermal Conductivity
Detector (TCD)with thenecessaryhardware, softwareandelectronic control toprovidedetector temperature
control, digital output signal andadditionally forproper FID fuel supplypressureandauto-ignition.
ThemicroFID is a 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. Thedata rate is100Hz.
ThemicroTCD is a fullydigital, universal detector. TheTCD consistsof a constant temperature filament that
senses change inpower required tohold the filament temperature constantwhen chromatographic
components elute. Thepowermeasurement isused todetermine theamount of the component eluting
from the column. Thedata rate is50Hz.
CALIDUS is controlledwithChromPerfect chromatographydata system fully integratedwith LineUp runningona

SIGNIFICANCEANDUSE
TheModel 201provides a simpleultra-fast analysis (10 to50 times faster than conventional lab
or processGC’s) of fixedgases andhydrocarbons toC
44
. Useof twodifferent PTCMs in series,
for exampleonepolar andonenon-polar columnmaterial enables leveraging the selectivity
differences for enhanced separations. Secondly, using two identical PTCMs virtuallydoubles
the column length.
Theanalyses areused for product specifications testing, product safety, environmental
measurements, process control, catalyst protection, educational tools, spot checksof fuels and
manymore.
