Agilent 490 微型气相色谱的惰性样品流路 低 ppm 级 H

To prevent adsorption of sulfur compounds, deactivation of the stainless steel surface of the sample path is required for the analysis of low ppm levels. This application note shows the separation, low level detection, and analysis perfor- mance of hydrogen sulfide and carbonyl sulfide using the Agilent 490 Micro GC in combination with a fully deactivated sample inlet.
