Three elements that cannot be ignored in the use of gas chromatograph

Abstract: gas chromatograph, a professional instrument in the industry, is particular about whether it is purchased or used. For this kind of instrument, there are three important elements that cannot be ignored in operation. Three elements of using a gas chromatograph 2 Cantilever beam: what is 3.5m/s

gas chromatograph uses

element 1: gas source purity

gas chromatograph is specially used for relevant detection and analysis of gas flow. Therefore, the purity requirements for the gas source are very high, and the purity requirements must reach more than 99.99%. However, many people do not strictly implement this requirement in the process of operation. Thus, because of the purity of the gas source, the detection baseline and height limit in the detection process are unstable. In short, when we select the most suitable material from a large number of engineering plastics of BASF, and the purity cannot reach 9.99%, the test results will be difficult to maintain a stable state, and there will be a steady stream of peaks. Moreover, if the purity of the gas source cannot meet the standard, the service life of the chromatograph will be affected

element 2: air flow ratio

at the same time, this instrument also has certain requirements for air flow ratio. In the process of using gas chromatograph for detection and analysis, its relevant proportion must be maintained. Usually the ratio is 6:1:1, or to ensure that the air volume can be larger, so as to give sufficient conditions to maintain high accuracy of the test results. Usually, the sensitivity and accuracy of detection can be guaranteed under this proportion

element 3: environmental requirements

although the temperature requirements of this instrument are not special, if it exceeds the relevant environmental temperature requirements, it is bound to affect the detection results. It is suggested that it is more standard to test at room temperature between 5 ℃ and 35 ℃

have you known the three important elements that cannot be ignored in the operation of the gas chromatograph? Based on these three basic elements, we can ensure the accuracy of detection. Because the meteorological flow will be affected by many factors, if you want to detect accurately, you must ensure that it is based on high-quality instruments, otherwise it is difficult to ensure the accuracy of the detected results

gas chromatograph, a professional instrument in the industry, is particular about whether it is purchased or used. As an instrument specially used to detect and analyze the flow direction of gas, its importance cannot be underestimated. This kind of instrument with high quality has super sensitivity and the advantage of effective detection. For this kind of instrument, there are three important elements that cannot be ignored in operation. It can be said that these three elements are fundamental to determine whether the internal parts are made of 304 stainless steel to determine the detection accuracy and whether effective detection can be achieved
