背压稳压阀升压进样是在样品气体压力等于柱前压力的条件下进样.这种进样技术能消除进样信号,有利于提高分析速度;能使用小的进样体积,得到大的检测信号;能充分发挥色谱柱的分离效能,采用较短的柱,适合于气体微量分析与在线分析.
Back Pressure Regulator Boosted injections are performed with the sample gas pressure equal to the pre-column pressure This injection technique eliminates the injection signal and helps to increase the speed of analysis; the ability to use small injection volumes Large detection signal; can give full play to the separation performance of the column, using a shorter column, suitable for trace gas analysis and online analysis.
