引言大多数过程或环境分析仪器都设计工作在试样入口端和出口端处试样流特性(例如:压力、露点)的规定极限内。此外,为了保证其正常功能,可能还需要一些辅助流体或其它有用物质。试样处理系统的作用是将一个或多个过程分析仪器与一个或多个源流体和环境连接起来,以满足过程分析仪器的要求,并使仪器有可能在经济合理的维护工作下,正常地工作一个以上合理的周期(参见附录A试样处理系统目 Introduction Most process or environmental analysis instruments are designed to operate within the specified limits of sample flow characteristics (eg, pressure, dew point) at the sample inlet and outlet ends. In addition, assistive fluids or other useful materials may be required to ensure their proper functioning. The purpose of the sample handling system is to connect one or more process analyzers to one or more source fluids and the environment to meet the requirements of the process analyzer and to make it possible for the instrument to operate normally and economically Work more than one reasonable cycle (see Appendix A sample handling system project
