SRI Inlet Systems
Every SRI GC is equipped with an unheated on-column inlet
system. On a Model 310 chassis, you can replace that with
any one of the other four inlet systems available—headspace,
split/splitless, purge and trap, and flash. On a Model 8610C
chassis, you can mount any of the inlet systems to a total
of five.
On-Column Inlet Systems
Suitable for 0.53mm capillary and 1/8" packed columns.
Includes EPC carrier gas controller and molecular sieve filter.
On-Column Inlet Systems
Description
Part No.
Additional On-Column Injector 8690023
Heated Static Headspace Inlet System
Ideal for the analysis of volatiles, especially where the sample
matrix is dirty. Sample is heated and injected via a sample
loop and gas sampling valve. Vial sleeve can be heated to
90°C. Requires 10–20mL of sample for operation.
Heated Static Headspace Inlet Systems

Part No.
Heated Static Headspace Injector 8690045
SRI Detectors
The SRI GC allows you to choose the detector(s) you want
installed. The chassis can accommodate as many as four
detectors to give you maximum flexibility.

Heated Split/Splitless Injector
Permits the use of narrow-bore capillary columns (0.32mm i.d.
and smaller) in either split or splitless modes. Allows 0.53mm
capillary columns and 1/8" packed columns to be used in
split, splitless or on-column modes. Injector temperature is
adjustable or programmable to 300°C.

Heated Flash Vaporization Injector
Vaporizes the sample prior to the column. Ideal for desorption
of SPME fibers or injection of extremely dirty samples. The
injector heater block can be heated to 300°C.
