Objective: To establish a simultaneous determination of Cl-
Br-
NO3-
SO42-
PO43- content of gardenia by ion chromatography. Method: The ICS-900 ion chromatography and IonPac AS11-HC inorganic anion exchange chromatography column
KOH gradient elution and conductivity detection were adapted to assay the five kinds of inorganic anion. Result: Cl-
Br-
NO3-
SO42-
PO43- were good in linearity. Samples recovery were between 97%-102%. The content of Cl-
Br-
NO3-
SO42-
PO43- were 0.084%
0.063%
0.070%
0.30% and 0.12%. Conclusion: The method is sensitive
accurate and operational
provided a simple and quickly method to assay the content of Cl-
