[Spectrodensitometric determination of lidocaine-chloride in antihemorrhoidal agents].
Spectrodensitometric method was used in determination of lidocaine-chloride in some antihemorrhoidal agents after thermomicrodetection and its direct thin layer coating. This procedure is based on transference of the studied substance into the gaseous state, its quantitative transference on the basic layer of silicagel GF254, isolation in the benzene-methanol mixture and its identification. Determination was performed by spectrodensitometric determination of absorption. The results obtained are precise and reproducible and the procedure is suitable for determination of lidocaine-chloride in micrograms.
