The present paper is aimed to study the optimal ionization conditions of 19 organophosphorous pesticides to be analyzed by gas chromatography (GC) with mass spectrometric (MS) detection in negative chemical ionization (NCI). Isobutane, methane, ammonia in methane, and pure ammonia were used as ionizing gases. The effect of the source temperature on the mass spectrum was evaluated for each pesticide...
This work presents a novel method for the detection of anabolic agents administration by the analysis of human urine. The method here presented allows both the screening and the confirmation of five anabolic agents at concentrations below 1μgl -1 , i.e. whenever it is not possible to obtain a full spectrum by gas chromatography technique with mass spectrometry detection unit (GC-MS) (single...
