Gas Chromatography

RAYLEIGH SP-3400 Gas Chromatography ( GC) Self-diagnostic Function : Core tests; Automatic tests; Extended tests; Basic tests; Monitor the status of GC continuously. Once finding faults, it will display the information, show the wrong zone and the setting method Self-protective Function : Overrun temperature protection; Short circuit hint; TCD filament protection; FID flameout hint Injectors : On-Column Injector for Packed Column; Flash Vaporization Injector for Packed Column; Automatic or manual gas inject valve; Headspace sampler; Thermal desorption system; Split/ Splitless Capillary Injector Detectors : TCD + FID Programming of Detector : Each of detectors has 5-ramp programmable time control, output-signal, attenuation range, and polarity can be changed automatically Temp. Range Column Oven : Ambient temperature to 420° C Cooling Time : 250° C to 50° C in 5 minutes Sensitivity Detector-TCD : e12000mv Ï mL/ mg ( for butane) Linear Range : 105 Filament Protection : If He or H2 carrier gas flow in the detector cell is off for 4 minutes, filament power automatically shuts off Max. Temperature Detector FID : 420° C Minimum Detectivity : d1.3× 10-12g/ s ( n-C16) Flameout Hint : Monitoring the status of GC continuously, after being turned on
