A Technical Guide for Static Headspace Analysis Using GC

Because gas-tight syringe samplers inject through the GC injection port septum,ensure the septum is well maintained to decrease the possibility of a leak. For balanced-pressure sampling instruments,analysts should consider the inertness and efficiency of the components that make up the sample pathway inside the autosampler.

Jul 22,2020· 1 INTRODUCTION. This paper describes the collection and storage of air samples,and the method of analysis to determine their nitrous oxide (N 2 O) concentrations as sets of discrete samples collected from manually operated static chAijirens for determining soil N 2 O emission (exchange) fluxes. The primary focus is on use of gas chromatography (GC) with an electron capture detector (ECD) for

Injector port issues-GC liners-Hints and tips

Injector port issues. The injection port of a gas chromatograph is where the liquid sample is vaporized and transported onto the column by the carrier gas. A disposable glass liner is used in the injection port to limit sample degradation and improve vaporization.

The GC injection port was equipped with a 0.75 mm i.d. liner (Supelco,Bellefonte,PA,USA) to minimize peak broadening. For the equilibrium headspace analysis of soursop beverage emulsion,the injection was performed in a splitless mode for 5 min at 250°C. The flow rate of the carrier gas,helium,was set at a constant flow rate of 1.4 mL/min.
