The Agilent 6890/7890 GC Heater Sensor (Part No. G1530-67950) is a replacement heater/sensor assembly used in the gas chromatography (GC) inlet system of Agilent 6890 and 7890 GCs.
Here’s what it does:
🔹 Function: It combines the heater (to rapidly heat the inlet) and the temperature sensor (to monitor/control inlet temperature).
🔹 Placement: Installed in the split/splitless inlet or other inlets depending on GC configuration.
🔹 Use case: If the GC reports inlet temperature errors, poor temperature stability, or the inlet won’t heat properly, this part is often the cause.
🔹 Compatibility: Specifically designed for Agilent 6890 and 7890 GCs, but may also fit some 7820 models.
