永久性气体分析气相色谱 TCD 系统
Biogas, natural gas, syngas and packaging headspace analysis rely on TCD with valve injection. This system uses a dual-filament TCD with sensitivity of at least 800 mV·mL/mg and a linear range of 10⁵ or more, a 0.25–1 mL gas sampling loop and columns such as molecular sieve 5A and Porapak Q. Send us your gas composition for column configuration.
