Determination of wrinkle treatment materials in tissue samples involves use of derivatizing-pyrolysis-gas chromatography-mass spectroscopy

摘要

Determination of wrinkle treatment materials in tissue samples is claimed per se, the process especially involving treating an internal standard-containing sample with a derivatizing reagent and then subjecting the sample to derivatizing-pyrolysis-gas chromatography-mass spectroscopy. ACTIVITY : Dermatological. MECHANISM OF ACTION : None given.
