[Determination of morphine and codeine in forensic chemical studies with the use of a single quadrupole mass-selective detector coupled to the HPLC system].

It was shown that a single quadrupole mass-selective detector coupled to the HPLC system can be used in forensic chemical practice for the detection and quantitative measurement of morphine and codeine in forensic in various biological objects. An algorithm for the reliable identification of opiates in a concentration range starting from 0.002 mg% with a relative error below 20% (mean ca 9.5%) is proposed.
