The rapid identification of human body fluids is meaningful for forensic casework. However, current methods suffer from several limitations such as poor sensitivity, time consumption and big sample consumption. Herein, we developed a mass spectrometry method to distinguish (blood, semen, urine, sweat, saliva) based on small molecular regions with no pretreatment, microliter high throughput. A highly sensitive salt-tolerance matrix N-(1-naphthyl)ethylenediamine dihydrochloride (NEDC) was used...
A high performance liquid chromatography tandem mass spectrometry/mass spectrometry (HPLC-MS/MS) protocol was developed for the determination of diphenylamine (DPA). Four productions DPA were selected qualitative assay and peak area main product ion quantitation. By means separation using an Agilent Extend-C18 column (CA, USA) (150 mm × 4.6 mm, 5 μm) with methanol-water (90:10) as mobile phase, detected by electrospray ionization (ESI) in positive mode. The linearity versus concentration...
摘要:
In this work, a novel method for high spatial resolution U-Pb dating of zircon by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at 10-16 μm spot diameter has been proposed. This was achieved introducing 2% (v/v) water-ethanol vapours into ICP in combination with the shielded torch system to increase sensitivity and suppress isotopic fractionation effect. Precise accurate concordant ages Plešovice, GJ-1, 91500 zircons were obtained using proposed method, results...
