建立了顶空气相色谱法测定阿昔洛韦中甲醇、乙醇、二氧戊环、苯和甲苯的残留量。色谱柱为DB-1毛细管柱,FID检测器。上述5种溶剂分别在5～1 000、8～1 600、0.6～120、0 15～6.0和1.42～284μg/ml浓度范围内线性关系良好。平均回收率为95.0%～100.0%,RSD为0.85%～2.75%。
A headspace gas chromatography was developed for the determination of the residues of acyclovir in methanol, ethanol, dioxolane, benzene and toluene. The column is a DB-1 capillary column, FID detector. The above five solvents showed good linearity in the range of 5-1 000, 8-1 600, 0.6-120, 0 15-6.0 and 1.42-284 μg / ml, respectively. The average recoveries ranged from 95.0% to 100.0% with RSDs ranging from 0.85% to 2.75%.
