We currently use headspace sampling to perform drug residue analysis. The headspace injection method adopts gas injection, and the analysis speed is fast. The organic solvent is not needed for extraction in the analysis process, which is less harmful to the analyst and the environment, easy to operate, less pollution to the column, simple spectrum, and is consistent with “ The analytical tools required by Green Analytical Chemistry are widely used in environmental monitoring, food and sanitation, headspace vials Chinese medicine composition analysis, organic solvent residue detection, and pharmacokinetics. As an analytical method, headspace analysis has three major advantages:
Headspace analysis is simple in the first place. It only takes the gas phase for analysis, which greatly reduces the interference of the sample matrix on the analysis. As a sample processing method for GC analysis, headspace is the easiest.
Second, headspace analysis has different modes and can be adapted to a variety of samples by optimizing operating parameters.
Third, the sensitivity of headspace analysis can meet regulatory requirements. Finally, combined with the quantitative analysis capabilities of GC, headspace GC headspace vials is fully capable of accurate quantitative analysis.
This is the end of the introduction of Headspace injection method for better drug residue analysis. I hope it can help you..jpg)
