摘要
油类物质(石油类物质和动植物油)作为水和土壤中的一种重要的污染源,不仅使水质不断地恶化,而且给人类的身体健康带来极大的危害。本文对非分散红外光度法(NDIR)测油仪的测油原理和内部结构进行了详细地理论分析。利用此仪器.可以检测出水中矿物油和动植物油的污染物含量,还可用于有机试剂纯度检测及含各种不同C-H键有机物总量和分量的测量。此测油仪采用了调节方便、频率精确的光源调制系统和相关检测技术,具有较高的灵敏度和稳定性,并且体积小适于野外现场使用。
As an important contamination in water and soil, the oil substance has been deteriorated the water quality and hurt the human health badly. The article analyses the non-dispersive infrared spectrophotometry oil instrument detailedly in principle and internal structure. The oil instrument can detect the total oil content of the water, moreover, it can be used for hallmark of the organic reagent and the different capacity of C-H in organic substance. The non-dispersive infrared spectrophotometry oil instrument adopts the lamp-house modulating system, which adjusted conveniently and has an exact frequency. In a word, it has a high sensitiveness and stability and it can be used in open country for the small volume.
