Abstract:The analysis of H9201 and pyrazosulfuron in mixture formulation by HPLC with C18 column using acetonitrile + water + acid as mobile phase and UV detector was introduced in this paper. Linear regression coefficient for H9201 and pyrazosulfuron was 0.999 9 and 0.999 8,respectively. The average recovery for H9201 and pyrazosulfuron was 99.58% and 99.6%,and RSD 0.28% and 0.28%,respectively. |
Key words:H9201;pyrazosulfuron;HPLC |
