Determination of Methane Emissions from Ruminants Sulfur hexafluoride tracer gas chromatography

1 Scope

This standard specifies the sulfur hexafluoride tracer gas chromatographic method for ruminant methane emissions. This standard applies to ranches such as cattle, sheep and camels.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. GB/T 8984 Determination of carbon monoxide, carbon dioxide and hydrocarbons in gases - Gas chromatographic method

3 Principle of the method

The permeate tube containing sulfur hexafluoride (SF6) was put into the rumen of the ruminant, and the methane (CH4) and the permeate produced in the rumen Of the SF6 with the ruminant breathing process together from the body. Collection and determination of CH4 and SF6 in ruminant exhaled gas samples Concentration, according to the penetration rate of the infiltration of SF6 to calculate the ruminant exhaled CH4 emissions.

4 Reagents and Materials

Except for air, unless otherwise specified, high purity gases (99.999% purity) are used for gases other than air. 4.1 Nitrogen (N2). 4.2 Pills. Veterinary equipment. 4.3 Gastric tube. Veterinary equipment, diameter according to animal selection. 4.4 rumen fistula. ruminant rumen in the back of the hamst on the capsule, and the outside of the channel. 4.5 SF6 standard gas. should be the same as the main components of the sample to be tested, nitrogen is dilution gas. 4.6 CH4 standard gas. should be the same as the main components of the sample to be measured, nitrogen gas as dilution.

5 instruments

5.1 Gas chromatograph 5.1.1 Equipped with an electron capture detector (ECD) and a hydrogen flame ion detector (FID), ECD and FID both use 5A molecular sieve columns. 5.1.2 Column preparation and treatment. 245μm ~ 198μm (60 mesh ~ 80 mesh) 5A molecular sieve into the outer diameter of 3mm stainless steel Packed column, column length 3m.
