Agilent G1544-80570 Split/Splitless Inlet Body with Heater for 6890N GC

Descripción

The Agilent G1544-80570 is a split/splitless inlet injection-port weldment, also known as the lower inlet body assembly. It forms part of the heated sample-inlet system used in gas chromatography and is compatible with Agilent 6850 GC, 6890 GC (including 6890N) and 7820A GC systems.

Included components

This assembly includes all four of the following components:

• G1544-80570: Split/splitless inlet weldment, lower inlet body assembly.
• G1544-61140: Split/splitless heater/sensor assembly.
• G1544-20570: Thermal block.
• G1544-60575: Split/splitless top insert assembly for EPC (electronic pneumatic control) systems.

These references identify the individual components of the assembly and are useful when matching replacement parts or servicing the inlet.

Application and function

The split/splitless inlet is the sample-introduction interface of a gas chromatograph. The inlet heats the injected sample to promote vaporisation before it reaches the analytical column.

In split mode, a portion of the vaporised sample enters the column while the excess leaves through the split vent. In splitless mode, the purge remains off during the initial sample transfer, allowing a greater proportion of the sample to reach the column before the purge flow opens. The appropriate mode depends on the sample and analytical method.
