A method for determining whether a fluid in an air-conditioning or refrigeration system has been altered is revealed. The method comprises preparing a non-radioactive label for a fluid used in the system, where the fluid is selected from a lubricant, a fluorescent dye and combinations thereof; adding a known quantity of the label to the fluid to form a labeled mixture of the fluid; performing an analysis of the labeled mixture to obtain a base-line profile of the labeled mixture; adding the labeled mixture to the system; providing the system to a user or customer; thereafter, performing an analysis of the fluid in the system to obtain a test profile; and determining whether the fluid in the system has been altered by comparing the base-line profile with the test profile of the fluid in the system.
揭示了一种确定空调或制冷系统中的流体是否被改变的方法。该方法包括为系统中使用的流体制备非放射性标签,其中流体选自润滑剂、荧光染料及其组合;将已知量的标签添加到流体中,形成流体的标签混合物;对标签混合物进行分析,以获得标签混合物的基线轮廓;将标记混合物添加到系统中;将系统提供给用户或客户;随后,对系统中的流体进行分析,以获得测试剖面图;通过比较系统中流体的基线剖面图和测试剖面图,确定系统中的流体是否被改变。
