What are the advantages and disadvantages of the five headspace analysis sampling methods of the headspace sampler?
2025-3-28 The headspace sampler is a convenient and rapid sample pretreatment method in gas chromatography. Its principle involves placing the sample to be tested in a sealed container, heating it to raise the temperature, allowing volatile components to evaporate from the sample matrix, achieving equilibrium in the gas-liquid (or gas-solid) two-phase system, and directly extracting the top gas for chromatographic analysis, thereby examining the composition and content of volatile components in the sample.
The difference in needle length of automatic headspace sampler and its impact on experimental results
2024-1-23 In modern laboratory analysis, the automatic headspace sampler, as an important analytical tool, is widely used in various fields such as environmental monitoring, pharmaceutical research, the food industry, as well as chemical engineering and geology. Its core function lies in accurately introducing samples into gas chromatographs for analysis, and the length of the needle becomes one of the key factors affecting this function.
