摘要: Abstract The application of direct analysis in real time combined with mass spectrometry (DART-MS) to the qualitative lubricant and oil additives, quantitative a antioxidant additive is reported. additives were analysed alone presence base oil, from filter paper, glass steel surfaces, showing potential DART-MS technique for direct, rapid additives. capabilities evaluated an matrix at concentrations range 0.1–8 mg/mL (1–80 μg on spot), using structural analogue as internal standard. linearity (R2 = 0.997), precision (% RSD = 2.6%) LOD (0.04 mg/mL oil) method demonstrates that capable determination without pre-extraction.
