Synchronized movements of the six-way valve and DIV made it possible to establish a simple flow path of the sample and a continuous liquid flow through the column.

六通阀和DIV的同步协调运行使得建立一个简单的样品流路和连续流体经过分离柱的系统成为可能。

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.

当分离组分或检测浓度时，设置采样阀以允许测量气体(液体)流过样品柱。当采样时，采样阀将待测量的气体(液体)引导到载气上的柱。

Propylene was vaporized from liquid to gas, then sampled to GC by gas sample valve, separated in 5A molecular sieve column, and determined with TCD.

先将液态丙烯汽化成气态，用气体进样阀将气态丙烯样品进样到气相色谱仪中，由5A分子筛填充柱进行分离，用TCD检测器检测，外标法定量。
