Principle 3
Acidic sweat extracted sample acrylonitrile extract was extracted with dichloromethane and concentrated by gas chromatography - mass spectrometer measurement
Fixed, external standard.
4 Reagents and materials
Unless otherwise indicated, the reagents used were of analytical grade water as a water GB/T 6682 regulations.
4.1 dichloromethane. chromatography, proven no interference peaks.
4.2 Acidic sweat. 0.5gL- liter of water containing Histidine hydrochloride monohydrate (C6H9O2N3 · HCl · H2O), 5g of sodium chloride
(NaCl), 2.2g of sodium dihydrogen phosphate dihydrate (NaH2PO4 · 2H2O), and treated with 1mol/L sodium hydroxide (NaOH) solution adjusted trial
Solution pH to 5.5 (± 0.2). This solution should be now with the current.
