4 Principle

Extract morphine, codeine, thebaine, papaverine, and narcotine in solid samples of suspected drugs. Using gas chromatography-mass spectrometry Use retention time, characteristic ion fragments, and ion abundance ratio as the basis for qualitative judgment; use gas chromatography to detect, and use chromatographic peak area as Quantitative basis, use external standard single-point method or internal standard single-point method to quantitatively analyze morphine.
