电化学生长和气相沉积涂层上建立的污染物在不锈钢表面上的电喷雾电离源的质谱仪的效果进行了研究，连同它们对仪器响应的鲁棒性的影响。使用白色光干涉测量法对扁平样品上的污染物累积进行定量，从而可以确定最有益的处理方法。与未涂覆的不锈钢表面相比，电化学生长的阳极氧化物和阴极氧化物膜以及掺杂有硅或氮的无定形碳膜的涂层导致污染减少，并且提供了改进的仪器响应的鲁棒性。
The effect of electrochemically grown and vapour deposited coatings on the build-up of contamination on stainless steel surfaces in the electrospray ionisation source of a mass spectrometer is investigated, together with their influence on the robustness of the instrument response. Quantification of the contamination build-up on flat samples, using white light interferometry, allowed the identification of the most beneficial treatments. Coating with electrochemically-grown anodic oxide and cathodic oxide films and amorphous carbon films doped with silicon or nitrogen resulted in reduced contamination compared with the uncoated stainless steel surface, and provided improved robustness of the instrument response.
