快速测定仪提供美国WILKS公司InfraCal CVH水中含油分析仪(红外油脂分析仪/总石油烃分析仪),国WILKS公司InfraCal CVH水中含油分析仪国内一级代理销售。
美国Wilks公司是世界*的红外设备供应商,在红外光谱领域有很强的技术积累。Wilks公司的InfraCal系列水中含油分析仪,包括HATR-T2,CVH和CH三个型号,都已经被认为是测量TOG/TPH,即总油脂含量、总石油烃含量的标准仪器,被国内外众多石油化工行业的实验室采用。
InfraCal CVH水中含油分析仪采用EPA方法413.2和418.1项或ASTM标准测试法D7066-04项,对应的提取溶剂分别为氟利昂,四氯乙烯,S-316,AK-225或其他红外线透射溶剂进行萃取,这些提取溶剂的特点是都重于水,提取后溶剂沉于水底,再采用相关方法提取出来。由于在分析过程中没有蒸发环节,因此CVH具有更高的测量精度。分析仪配备有一个内置的凹槽,整个分析需要不到10分钟,仪器精度zui高可达到为2 ppm。
InfraCal CVH的特点
1、仪器操作简单快捷,人性化设计,响应快速,性能稳定;
2、在操作时将装有待测样品的比色皿至于仪器中进行测量即可;
3、测量时间在10-15分钟内,包括样品前处理;
4、测量范围大,可检测2-4000ppm之间的浓度;
5、可检测样品中所有油类和芳香烃类物质的含量
6、可选用多种萃取溶剂,例如全氯乙烯,氟利昂-113, AK-225 orS-316等等
7、各种测试TOG/TPH的场合均可使用
InfraCal CVH水中含油分析仪的原理
Infracal型TOG/TPH红外分析仪是基于快速测定水和土壤样品中总油脂(TOG)和总石油烃(TPH)浓度的红外光谱方法,其工作原理符合朗伯-比尔定律。即用一束强度为I0的特征红外光照射样品,由于油脂对特征红外光产生吸收,透射光强度会减弱为I,样品对特征红外光的吸光度则为A=lg I0/I。根据光吸收的朗伯-比尔定律,吸光度与样品中油脂浓度(C)的关系为A=abC,其中a为吸光系数,b为样品池厚度,即样品的吸光度与油脂浓度成正比。通常厂家出厂时已经用一组溶度已知的待测样品建立了标定体系,用户可以得知吸光度与油脂浓度的关系式,根据该关系式和被测样品的吸光度,可以求出被测样品中的油脂浓度。
