浩瀚药典二氧化碳用标气HH-CH4/CO2

碳氢化合物照气相色谱法(通则0521)测定供试品气体取本品,即得对照品气体取甲烷含量为0.0020%的气体(以氮气为稀释剂)。

浩瀚色谱，依据药典二氧化碳2020年版中对碳氢化合物的要求生产出甲烷标准气体，规格4l/8l，铝合金，同时配套减压阀，净化装置。

 
Hydrocarbons are measured by gas chromatography (General Rule 0521) and the gas of the test product is taken from this product, that is, the reference gas is obtained as a gas with a methane content of 0.0020% (with nitrogen as the diluent).

Haohan Chromatography produces methane standard gas according to the requirements for hydrocarbons in the 2020 edition of the Pharmacopoeia carbon dioxide, with a specification of 4l/8l, aluminum alloy, and is equipped with a pressure reducing valve and a purification device.
