Bicchi and Bertolino [193] analyzed a variety of pharmaceuticals for residual solvents. Samples were equilibrated directly or dissolved in a suitable solvent with a boiling point higher than that of the residual solvent to be determined. Equilibration conditions were 90 or 100°C for 20 min. A Perkin-Elmer HS-6 headspace sampler was used. The chromatographic phase chosen was a 6 x Vs in. column packed with Carbopack coated with 0.1% SP 1000. Residual ethanol in phenobarbital sodium was determined by a direct desorption method. An internal standard, /-butanol, was used. Typically, 0.44% of ethanol was detected (compared to a detection limit of 0.02 ppm). The standard deviation of six determinations was 0.026. Pharmaceutical preparations which were analyzed by the solution method included lidocaine hydrochloride, calcium pantothenate, methyl nicotinate, sodium ascorbate, nicotinamide, and phenylbutazone. Acetone, ethanol, and isopropanol were determined with typical concentrations ranging from 14 ppm for ethanol to 0.27% for acetone. Detection limits were as low as 0.03 ppm (methanol in methyl nicotinate).

For thyroxine measurement linearity was obtained between 25 and 400 nmol/1, for lidocaine between 5 and 50 pmol/1, i.e., in the clinically relevant range. Lidocaine has been determined in plasma samples with a measuring time of 15 min per sample. The method is also applicable to other haptens such as digitoxin, theophylline, and phenobarbital. Increasing the sensitivity up to that of conventional RIA should make this kind of assay of practical utility. 

We have also tested several other anticonvulsant drugs and found that carbamazepine, phenobarbital, lidocaine, and...
