Determination of Chloride and Sulfate in Gallonium Phosphate
Column: anion column + anion guard column
Eluent: Na2CO3 + NaHCO3
Flow rate: 1.50 mL / min
Detector: Suppresses conductivity detection
Injection volume: 25 mL
Column and detector temperature: 36 ° C
Note: glufosinate is zwitterionic, but acid is significantly stronger than alkaline, if not pretreated, then glufosinate can also be detected in the inhibition of conductance. The method uses a cation exchange resin to retain glufosinate, and the anion is allowed to enter the solution for determination.
