Chemical Testing Technologies
Chemical testing technologies are mainly used to detect chemical components and contaminants in food, including:
- Gas Chromatography (GC): Suitable for analyzing complex samples, with high sensitivity and selectivity.
- High-Performance Liquid Chromatography (HPLC): Commonly used to detect pesticide residues, heavy metals, and other chemical contaminants.
- Mass Spectrometry (MS): Used in conjunction with GC or HPLC to provide high-precision qualitative and quantitative analyses.
- Spectroscopic Methods: Such as atomic fluorescence spectrometry and atomic absorption spectrometry, used to detect heavy metal elements.
