A capillary gas-liquid chromatographic (GLC) and an ion-pair high performance liquid chromatographic (HPLC) method were developed for the assay of atropine sulphate and obidoxime chloride from a parenteral solution in commercial automatic injection devices. The injectors are aimed for the emergency treatment of poisoning by nerve agents. The two-step GLC method consists of extraction of atropine as a free base prior to GLC analysis using scopolamine as an internal standard. Obidoxime is determined directly in a diluted sample solution by reversed-phase HPLC using sodium 1-heptanesulphonate as a counter ion in the mobile phase. The relative standard deviation (R.S.D.) was 1.81% for the GLC procedure with injectors containing only atropine and 2.37% for the GLC of atropine in atropine-obidoxime injectors. The R.S.D. for the HPLC procedure of obidoxime in atropine-obidoxime injectors was 0.82%. The corresponding R.S.D.s for the sampling of atropine-obidoxime injectors were 0.36% and 0.27%. The coefficient of determination (r2) was 1.000 for both methods. The recoveries at the target concentration averaged 101.0% and 98.7% with a standard error of the mean of 0.30 for both methods. The retention times for atropine and obidoxime were 6.27 and 4.29 min, respectively.
