How many types of headspace are there?Headspace vials are a type of specialized sample container used in analytical chemistry, particularly in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) techniques. These vials are designed to facilitate the analysis of volatile compounds in a sample. During analysis, the headspace vial is heated to a specific temperature, which causes the volatile compounds in the sample to vaporize and equilibrate within the headspace. The gas phase in the headspace is then samp...

What are the advantage of HPLC autosampler?HPLC (High-Performance Liquid Chromatography) autosampler is a device used in analytical chemistry to automate the injection of samples into an HPLC system. In HPLC, a sample is typically introduced into the system through an injection port, where it is then carried by a mobile phase (liquid solvent) through a chromatographic column. The components of the sample separate based on their chemical properties as they interact with the stationary phase within the column. 9 mm Short Thread Vial...
