一般描述
On-Column injection is generally performed to avoid vaporization of samples. This method involves injecting the cold sample directly on the column. Using retention gaps allows autosamplers to use on-column sample injection method. In this system, a 32-gauge needle is inserted in a cool narrow bore injection valve and then into capillary column.
此类 Hamilton 注射器的固定针头设计可最大程度减小死体积。不锈钢针头，长 12.5cm(用于 Agilent/HP 进样器)或 7.5cm(用于 Carlo Erba 进样器)×0.24mm 外径 (32ga.)，针尖 90°。用于内径等于或大于 0.32mm 的色谱柱。
应用
It may be used in a study done to understand the variations of capillary on-column fixed needle injection system in gas chromatography.
