Introduction

Background and significance of standard formulation

With the increasing severity of global climate change, methane emissions from ruminants (such as cattle and sheep) in agricultural activities have become one of the important sources of greenhouse gases. In order to reduce the impact of methane on the environment, the GB/T32760-2016 standard came into being, aiming to accurately determine the methane emissions of ruminants through sulfur hexafluoride tracer gas chromatography.

Method principle and technical evolution

This standard uses sulfur hexafluoride (SF6) as a tracer gas and puts it into the rumen of ruminants through a permeation tube. Methane (CH4) and SF6 in the rumen will be exhaled from the body. The CH4 and SF6 concentrations in the exhaled gas are detected by gas chromatograph, and the CH4 emissions of ruminants are calculated in combination with the SF6 permeation rate of the permeation tube.

Implementation recommendations and practical applications

Instrument calibration: Calibrate the gas chromatograph regularly to ensure that the measurement accuracy of SF6 and CH4 is within the allowable error range.

Sampling operation: Strictly follow the standard regulations, select the appropriate permeation tube size, and ensure that the pressure of the sampling device is properly controlled to avoid gas leakage affecting the accuracy of the results.

Data analysis: It is recommended to use professional software to process and analyze gas chromatography data and generate detailed emission reports to facilitate subsequent research and policy formulation.
