Abstract

The invention discloses a gas-chromatography measuring method for the hydrogen content in blood. The method includes the following steps that (1) to-be-measured gas and background gas are prepared with the headspace method; (2) gas chromatography conditions are selected; (3) sample feeding is carried out through an automatic sampler, the to-be-measured gas and the background gas are separated through a chromatographic column, and then immediately enter a detector, sample components are changed into electrical signals through the detector, and the electrical signals are amplified and recorded to form a gas chromatogram; (4) a peak value of hydrogen in the to-be-measured gas subtracts a peak value of hydrogen in the background gas to obtain a difference value, and the difference value is a peak value of hydrogen in the blood. The gas-chromatography measuring method is high in accuracy and easy and convenient to operate, and accurate detection of the hydrogen content in human blood can becompleted in half an hour.

Description

technical field [0001] The invention relates to the technical field of analysis, in particular to a gas chromatography determination method for hydrogen content in blood. Background technique [0002] Many recent studies in the field of medical biology have obtained a lot of evidence with various animal models and human experiments, suggesting that hydrogen has a very wide range of medical effects. There is a lot of evidence that hydrogen is very safe for the human body. Through a detailed investigation of the diet, work and rest, and physiological parameters of the long-lived elderly, it was finally found that the hydrogen content in the blood of the long-lived elderly is 3-4 times that of ordinary people, and it has nothing to do with environmental factors such as region, race, and eating habits. Therefore, This value can be used as one of the parameters for evaluating a person's health status. Therefore, it is very important to accurately measure the content of hydrogen...
