学习自控仪表

这个是横河气相色谱仪中的一段话：
The process gas chromatograph consists of a sampling mechanism, a column and a detector.
Sampling is carried out by switching a sampling valve. When separating components or detecting concentrations, the sampling valve is set to allow the gas (liquid) to be measured to flow through the sample column. When sampling, the sampling valve leads the gas (liquid) to be measured to a column on a carrier gas. (See Figure1.1)
There are two important points regarding sampling: a regular volume is sampled since repeated sampling is required; and samples are taken quickly and securely. The volume is fixed by measuring a specific gas (liquid) of controlled temperature and pressure using a sample measurement tube. Samples are taken quickly and securely by ensuring that the gas to be measured always flows without interrupt.
