*Requires Gettered Carrier Gas (Not Included with Instrument)



This particular 7890B features a dual PDHID, Helium Purifying Getter, which is to be used in addition to ultra high purity gas. This is a gas-sampling GC with has a single gas sample introduction bulkhead and is capable of analysis on all 3 detectors concurrently. The PDHID detectors have been tested and are working, the output signal is below 2000 for both.

The carrier gas is one of the most critical gases entering the GC system. Even very pure gas cylinders can contain about 10 ppm of oxygen, water and hydrocarbons. Although these concentration levels are normal, they can be detrimental to a GC system, especially those using ultra sensitive detectors such as the pulse discharge helium ionization detector (PDHID). A typical sign of carrier gas contamination is an erratic baseline, including baseline wandering, drifting, or excessive noise.
