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。分析仪配备有一个内置的凹槽，整个分析需要不到10分钟，仪器可为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，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。 InfraCal CVH技术参数 类型：固定滤光片滤光测试仪 规格：6.5×6.5×5英寸（165×165×225mm） 重量：4.5磅（2.0kg） 显示：4位7段红色LED屏，字高度5/8英寸 电源要求：电压12V直流，+2% 功率：7.5瓦，标准5瓦 输入接口：switchcraft 760或类似插头，为正 建议电源：交流电源；交流/直流转换器类型（标配） 12v自动电池连接器插头（选配） 便捷式12v电池组（选配） 标准使用测量范围： 水：2-1000ppm（用于10：1的萃取率） 土壤：3-5000ppm（用于1：2的萃取率） 可用萃取溶剂：氟利昂，全卤代烃，S-316,AK-225 或其他可透过溶剂 分析时间：10-15分钟，包含萃取过程 运行温度范围：40华氏度（4摄氏度）到110华氏度（45摄氏度） 用户选择性校准：0点平衡调节 多20点曲线拟合法校正 仪器可重复性+/-1ppm CVH红外分析仪测定TOG/TPH的使用场合 ---在近海石油平台上对生产用的样品水进行分析 ---监控炼油厂排放物、废水处理或工业装置 ---测定油/水分离系统的效率 ---地下储存罐周围的土壤指标研究 ---测量预清洗金属部件表面上的残存油 ---测定回收溶剂的纯度水平 ---其它对水或土壤进行现场测定的场合 InfraCal Model CVH详细规格参数 Instrument Te | Fixed Filter Infrared yzer, Model CVH | ytical Wavelength/Wave Number | 3.4 μm, 2930 cm-1 | Power Requirements | 12 Volts DC, 2.0 amps, 12 Volt battery pack or adapter available | Power Supply | Universal AC/DC | Weight | 4.4 lbs.
