Q Tubing between the gas cylinder and gas chromatograph
Fig. 1.3.4 Tubing between the gas cylinder and gas chromatograph
Use tubing with a 3 mm O.D. and 2 mm I.D. between the gas cylinder and gas chromatograph.
The use of a gas filter is highly recommended. Contaminated tubing or poor quality gases
can interfere with baseline stability.
<Option> Gas filter (P/N 221-05619-01)
This absorbs organic compounds and moisture in the supply gas, improving its
purity. The filter can be regenerated by baking in the GC oven at 250 °C with
30 mL/min carrier gas purging the filter.
Capacity: Approx. 200 mL
Absorbent: Molecular sieve 5 A
