Abstract
The objective of the study is to evaluate the potential for the use of cards for sampling and transportation of biological material during forensic chemical and toxicological examinations by the example of a biological sample, urine containing zopiclone. Two methods of sample preparation were compared. The use of cards for the collection and transportation of biological material, such as urine, followed by high-resolution high-performance liquid chromatography-mass spectrometry (HPLC-MS) for the identification of zopiclone metabolites was shown to be beneficial in forensic chemical and toxicological examination. The validation evaluation of the proposed sample preparation and identification method met the acceptance criteria.
