Features of micro-extraction of the headspace solid phase
Jan. 7th, 2020
Solid phase micro-extraction (SPME) technology is a new sample pretreatment method developed based on solid phase extraction technology. Headspace Solid phase micro-extraction (HS-SPME) is the extraction head vertically placed in the gas phase above the liquid or solid sample for analysis, extraction, adsorption of volatile or semi-volatile components.
In Headspace Solid phase micro-extraction experiment, choose GC headspace vial is very important. Aijiren supply GC headspace vial for sale.
HS-SPME is especially suitable for the enrichment of micro-volatile components, easy to operate, can effectively reduce the impact of interference substances in substrates and liquid substrates, with collection, extraction, concentration, sample, analysis in one unit, no solvent, easy to achieve automation, convenient and chromatographic instruments combined and so on. Solid phase extraction and gas chromatography-mass spectrometry are methods developed in recent years to analyze volatile aroma composition sandals and pesticide residues in water and fruits and vegetables.
