Description: One Pre owned HP 6890 with LAN, TCD, FID and Switching Valves. The GC (G1540A) includes a TCD with Purge Packed Inlet, a FID with Split/Splitless Inlet, and switching valves. The unit is 220 volt (not the standard 120V). Since receiving the system we have connected the system to gases and Chemstation software (computer and software not included). We have verified that the inlets, oven, and detectors appear to be in working condition as the inlets, oven, and detectors heat and stabilize and the detector signal response is good. We have not tested the any of the switching valves or accessories as we are not familiar with how to test them.
