Repeatability is a very important parameter in the analysis of gas chromatographs GC vials manufacturer. Good instrument repeatability means that the accuracy of quantification and qualitative is directly related to the quality of analysis.
In the use of gas chromatography instruments, we first require the maintenance and installation of the instrument as required by the instructions and the manufacturer's requirements, to ensure that the instrument can be restored after disassembly and maintenance, so that the instrument's tightness is guaranteed, typical An example is the correct installation of graphite pads, "O" rings, etc. Secondly, as much as possible, the analyst is a skilled person using a gas chromatograph - the most important thing is to be able to manually perform manual injection, if not guaranteed At this point, it is recommended that the analyst perform more manual injection exercises; in addition, if the laboratory funds allow, you can purchase equipment such as liquid autosampler, which can eliminate the impact of labor and improve the repeatability of the analysis process.
However, the actual situation is that the above problems are solved, and in many cases, repetitiveness is still a major problem that plagues laboratory analysts. The possible effects of liners on gas chromatographic analysis repeatability are described below.
The liner is an important part of the capillary inlet of the gas chromatograph. Its function is to help the sample to volatilize, capture high boiling point, non-volatile substances and impurities, protect the column and provide shunt isolation channels GC vials manufacturer.
This is the end of the introduction of Factors affecting the repeatability of gas chromatograph analysis: liner. I hope it can help you.
