SRI Detector 偵測器


► Up to 4, 5, or 6 Detectors can be Installed
    on One 8610 GC
 Several Detectors can be Run in Series for Multiple
    Chromatograms from One Injection

 

GC Detector Overview (16 types)

Each detector is equipped with Electronic Pressure Controlled (EPC) support gases, such as hydrogen and air for the FID, a thermostatted heater block for temperature stability, and internal amplifier electronics. All detectors require factory installation. Prices listed are for the detector mounted on an SRI chassis.
