Chemical additives are incorporated into commercial lubricant oils to modify the physical and chemical properties of the lubricant. The quantitative analysis of additives in oil‐based lubricants deposited on a surface without extraction of the sample from the surface presents a challenge. The potential of desorption electrospray ionization mass spectrometry (DESI‐MS) for the quantitative surface analysis
将化学添加剂掺入市售润滑油中以改变润滑剂的物理和化学性质。对沉积在表面上的油基润滑剂中的添加剂进行定量分析而不从表面提取样品提出了挑战。评估了在不提取样品的情况下,对复杂油基体中的油添加剂进行定量表面分析的解吸电喷雾电离质谱(DESI-MS)的潜力。
