Automatic headspace sampler function:

In chromatographic analysis, increasing work efficiency (ie, the number of samples that can be analyzed per unit time) headspace vials manufacturer is a goal that people have been pursuing. From packed columns to capillary tubes, from manual injection to automated injection, from routine chromatography to fast chromatography, productivity is increased. From the current instrument, the analysis time of the GC itself has been quite short. In contrast, sample processing is often time-consuming. Statistics show that chromatographic laboratories usually process samples 60% of the time. The actual GC analysis takes only 10% to 15% of the time. The rest of the time is applied to data processing and report editing. So how to speed up or simplify the sample Processing is a key issue to improve work efficiency. Many good methods have been developed in this area, such as solid phase extraction (SPE), solid phase microextraction (SPME), supercritical fluid extraction (SFC), etc. However, if we only have a sense of volatility in complex samples Interests, such as organic volatiles in wastewater, alcohol content in the blood of drunk drivers, etc., are obviously more time consuming, and in this case, headspace chromatography is often a simple and effective method. The so-called headspace analysis is a chromatographic analysis of the gas phase above the sample matrix (liquid and solid).headspace vials manufacturer
