定义化学传感器是一类可将化学信息转换为有用分析信号的器件。上述化学信息可以是某种特定样品组份的浓度,也可以是全组份分析。这种化学信息可能来源于被分析物的化学反应或者被测体系的物理性质。物理传感器则是用以提供系统物理性质信息的一类器件。化学传感器是分析器的基本部件,除了传感器之外,分析器还具有实施如下功能的部 Definition Chemical sensors are a class of devices that convert chemical information into useful analytical signals. The above chemical information may be the concentration of a particular sample component or it may be a full component analysis. This chemical information may come from the chemical reaction of the analyte or the physical properties of the system under test. Physical sensors are a type of device used to provide information about the physical properties of a system. The chemical sensor is an essential part of the analyzer, and in addition to the sensor, the analyzer has a part that performs the following functions
