三、技术原理

     格林凯瑞GL-7100型红外分光测油仪原理  当某单色光通过被测溶液时,其能量就会被吸收。光强度被吸收的强弱与被测物质的浓度成比例,符合朗伯比尔定律: A=log(1/T)=log(I0/I)=a×b×c。根据HJ637-2018国家标准,用四氯乙烯或者用四氯化碳萃取水中的油类物质,然后使用无水硫酸钠隔离杂质和水分,分离出油和四氯乙烯或者是四氯化碳的溶液,测定总萃取物含油量。同时可以将萃取液用硅酸镁吸附,经脱除动植物油等极性物质后,测定石油类。总萃取物和石油类的含量均由波数分别为2930cm-1(CH2基团中C-H键的伸缩振动)、2960cm-1(CH3基团中C-H键的伸缩振动)和3030cm-1(芳香环中C-H键的伸缩振动)谱带处的吸光度A2930、A2960和A3030进行计算。动植物油的含量按总萃取物与石油类含量之差计算。
