Agilent 7890B hard glass column 2m * 1/4 detailed information:
Haohan Chromatography optimized the pre-treatment conditions for different substrates of seawater, marine sediments, and seafood, and established GC-MS/MS analysis methods for polychlorinated biphenyls and pesticides, respectively. Solid phase extraction technology is used for pre-treatment of seawater. By adding 1% methanol and adjusting the pH value to 3.0, Oasis HLB solid-phase extraction is used. 6mL of n-hexane: dichloromethane (1:1) is used as the elution solvent, which can fully enrich polychlorinated biphenyls and pesticides in seawater for chromatographic analysis.
