[Use of thin layer chromatographic analysis in forensic medical analysis of urine for opiates].

The study results of identifying the opium alkaloids (morphine, codeine and their synthetic analogue heroin) in urine during the forensic chemical examinations by using the method of thin-layer chromatography (TLC) are described. Several solvent systems and chromogenic reagents designed for the TLC analysis of opiates are presented. Solvent systems were defined to separate the opiates (isolated from urine) in Sorbphyl plates; besides, a chromogenic reagents' kit was suggested to detect them in the forensic medical analysis of urine. There is a description of the study method.

[The determination of phoxim in cadaveric material by gas-liquid chromatography].

The developed gas-liquid chromatographic procedure for forensic chemical detection and measurement of phoxim in cadaveric material permits the detection in 25 g of an organ of 44 to 52% of added phoxim. The threshold of phoxim measurement in 100 g of the liver is 0.04 mg, the least volume of phoxim detectable being 0.02 g. The developed gas-liquid chromatographic technique should be used as an additional method together with thin-layer chromatography, for a more objective evaluation of the results of forensic chemical analysis of cadaveric material for phoxim.

[Analysis of errors allowable in conducting forensic chemical studies].

The authors have analyzed methodologic errors made by chemical experts in records of forensic chemical investigations selected at random. The major errors are classified and their frequency determined in relation to the complexity of the task. Suggestions are made aimed at improvement of the quality of forensic chemical investigations.
