一般描述

The liner is the second most important part of the inlet. It is the centrepiece of the inlet system, basically a glass tube between the septum and the column, where the sample is evaporated and brought into the gas phase. There are three most important parameters one should keep in mind while choosing a liner, firstly liner volume, considering a typical liner has a volume of 900μl, secondly liner treatment, one should always use a deactivated liner, so that the glass does not react with the analytes introduced in the liner, thirdly liner design, different designs are available like straight, tapered, baffled and without glass wool and one should be careful enough while choosing the design such that it is compatible with the desired injection mode.
Deactivated (silanized) glass inlet liner for packed injection ports.

• Fits Agilent (5890, 6890, and 7890)

应用
