Purification should be efficient enough so that chromatographic retention is not influenced by the matrix; Separation by capillary gas chromatography (HRGC), which will provide sufficient separation of analytes; Identification by suitable detectors such as an electron capture detector (ECD) or a mass-selective detector (MSD), or by either low-resolution mass spectrometry or high-resolution mass spectrometry (LRMS or HRMS); Quantification according to internal standard methodology (for reference, see UNEP 2004a); Reporting in accordance with regulation(s).
(د) تحديد الكاشفات المناسبة مثل كاشف الإلكترونات (ECD) أو الكشاف الانتقائي للكتل (MSD) أو بمطياف الكتل منخفض الاستبانة أو مطياف الكتل عالي الاستبانة (LRMS, HRMS)؛
