二.油分析仪器的标准操作被设计为监测碳氢基润滑油.所讨论的某些特殊参量与合成油分析直接有关.例如,酯基油中氧化物的观察,如果没有所使用的分析范围的变化,将是不可能的,因为酯的吸收将会“淹没”羧酸的吸收.油的红外光谱包含着各种频率上的信息.它们与特定成分的存在或缺乏有关.例如,油的氧化物使吸收率在1800～1650cm~(-1)的范围内增加.定量分析报告以积分面积的形式给出,这比单纯测量频带高度或亮度更精密而准确.在每种情况下,为了计算该面积,需选择局部基线.在大多数情况下,基线点应以实验为依据,在大范围试验中选择.抗磨剂和乙二醇面积这两个范围应单独使用,以确保在一个区域内,如果一种污染物的过量引起某种成分的测量畸变,则通过另一个区域内该种成分的低水平可以识别出来.换言之,这些成分测量的置信度可通过使用两个独立的区域予以改善.
The standard operation of oil analysis instruments is designed to monitor hydrocarbon-based lubricants Some of the special parameters discussed are directly related to the analysis of synthetic oils, for example, the observation of oxides in ester-based oils, without the analytical range used Will not be possible because the absorption of the ester will “submerge” the absorption of the carboxylic acid.The oil’s infrared spectrum contains information on a variety of frequencies that are related to the presence or absence of a particular component.For example, Oxides increase the absorbance in the range of 1800 to 1650 cm -1 Quantitative analysis reports are given in terms of the integrated area, which is more precise and accurate than simply measuring the band height or brightness In each case, In most cases, the baseline point should be experimentally based and selected from a wide range of tests. The two ranges of anti-wear agent and glycol area should be used separately to ensure that in one Region, an excess of a contaminant can cause a distortion of the measurement of a component to be identified by a low level of that component in another region.In other words, confidence in the measurement of these components can be determined by using two independent Region to be improved.
