Method for detecting and measuring low concentrations of contaminants using attenuated total reflectance spectroscopy in the mid-IR range
Abstract:
A spectroscopic method is disclosed for detecting and measuring contaminants in fluids such as water or oil, where the hydrophilicity of the contaminant is substantially different from that of the contaminated fluid. Good calibrations can be obtained at very low concentrations using infrared spectroscopy with ATR crystals that have not been additionally coated or otherwise modified.
Abstract(Chinese):

公开了一种用于检测和测量诸如水或油的流体中的污染物的分光方法，其中污染物的亲水性与污染流体的亲水性基本上不同。 使用没有另外涂覆或以其他方式修饰的ATR晶体的红外光谱可以在非常低的浓度下获得良好的校准。
