During lactation, Cd-levels in human milk were determined by means of flameless atomic absorption spectrophotometry. The levels in colostrum were some 50-65% higher than in transitional and mature milk.

[The gaschromatographic mass spectrometric detection of amphetaminile (author's transl)].

Detection of Amphetaminile by GC/MS is presented. In diethyl ether solution the main peak is that of 2-benzylidenamio-1-phenylpropane, which has a retention time of 23,2 minutes under the condition delineated. Under these conditions HCN is eliminated from the Amphetaminile.

[Investigations of the decomposition and detection of morazone by thin-layer- and gas-liquid-chromatography].

Three decomposition products of Morazone (ingredient of the pharmaceutical preparation Rosimon-Neu) were observed following heat treatment in acid medium (hydrochloric or tartaric acid). These products were isolated by TLC and identified as bis-antipyryl-methane, phenmetrazine and 4-hydroxymethyl-antipyrine by mass spectrometry and IR-spectroscopy and 1H-nuclear magnetic resonance. Morazone and the metabolite phenmetrazine may be extracted from alkaline urine using chloroform, however acid hydrolysis (pH 1) of the urine before alkaline extraction will improve the sensitivity of detection of morazone by producing the metabolite phenmetrazine in addition to bis-antipyrylmethane. The metabolite 4-hydroxymethyl-antipyrine is barely detectable by TLC from alkaline extraction of urine.
