An analytical case study of bromoderma by ion chromatography and x-ray spectrogram (PIXE)

An analytical case study of bromoderma by ion chromatography and x-ray spectrogram (PIXE).Some chemicals with cas registry numbers like 15876-67-2 and 24959-67-9 are also used. Hoshika, Y.; Yukawa, M. (Sch. Med., Shinshu Univ., Japan). Biomed. Res. Trace Elem., 2(2), 255-6 (Japanese) 1991. CODEN: BRTEE5. ISSN: 0916-717X. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Blood serum Br-, serum, urine, and saliva anions, and skin epidermal Br-, Zn, Ca, and Fe were detd. by ion chromatog. and particle-induced x-ray emission (PIXE) spectrometry in humans treated with the Br--contg. cholinergic agents Mestinon and Ubretid. Only the levels of Br- and Zn were elevated, with serum Br- reaching 15.8 ppm (4-times normal level). .

The analysis of quaternary ammonium compounds in human urine by direct-inlet electron-impact-ionization mass spectrometry

The analysis of quaternary ammonium compounds in human urine by direct-inlet electron-impact-ionization mass spectrometry. Nisikawa, M.; Tatsuno, M.; Suzuki, S.; Tsuchihashi, H. (Forensic Sci. Lab., Osaka Prefect. Police Headquaters, Osaka 540, Japan). Forensic Sci. Int., 51(1), 131-8 (English) 1991. CODEN: FSINDR. ISSN: 0379-0738. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 1 An accurate and rapid screening test for nine quaternary ammonium compds. (suxamethonium chloride, pancuronium bromide, ambenonium chloride, benzethonium chloride, distigmine bromide, methylbenactyzium bromide, neostigmine bromide, propantheline bromide, and pyridostigmine bromide) by direct-inlet electron-impact-ionization mass spectrometry (DI/EI-MS) was investigated. Each compd. was extd. from urine as an ion pair with KI3 into dichloromethane. 15876-67-2 and 115-79-7 are cas registry numbers of chemicals which are used as reagents here. The reliability of the identification of these compds. was verified by the mass chromatog. anal. of their characteristic fragment ions. The anal. of these drugs by DI/EI-MS could be performed within 5 min. The detection limits were between 20-150 ng/mL for the nine compds. This method appears to be efficient, rapid, and suitable as a screening procedure for the quaternary ammonium compds. found in urine. .
