Reference REFERENCE INSTRUMENT DESCRIPTION CARRIER GAS The Varian, Inc. CP-4900 Micro-GC is configured for the use with either He (or H ) or N (or Ar). Having chosen one option definitely rules out the use of the other without the instrument undergoing internal changes prior to any switching of carrier gas type.
Page 46: Micro Electronic Gas Control (Egc)
VENT MICRO ELECTRONIC GAS CONTROL (EGC) The CP-4900 Micro-GC has built-in Micro EGC regulators that can be adjusted to get a constant or programmed pressure control, which result in a constant or programmed flow through the injector, column and detector. The pressure range of the Micro EGC is between 50-350 kPa (7 - 49 Psi).
Page 47: Column
Table I shows several standard columns as supplied in the CP-4900 Micro-GC and selected applications. Other columns are available by contacting Varian, Inc.
Page 48: Detector
Reference DETECTOR The CP-4900 Micro-GC is equipped with a thermal conductivity detector (TCD). This detector responds to the difference in thermal conductivity between the carrier gas and the sample components. The construction of a TCD is such that the changing thermal conductivity of the carrier gas stream, due to components present, is compared to the thermal conductivity of a constant reference gas stream.
Page 49: In/Outputs
The CP-4900 Micro-GC has several in/output ports accessible inside the instrument for interfacing with external devices. Open the cover. At the front of the CP-4900 Micro-GC, the external device connectors will be visible. Close the cover after connecting the cables! Varian, Inc.
