[Liner] according to the type of presentation mode vaporization of the sample can be divided into three different injection methods: 1, direct injection of the entire sample was immediately transferred to a column in the post-vaporization. Samples in the inlet of the transmission rate is determined by the column flow and liner volume. This approach is typically used 0.53mm injection capillary and packed columns. The injection volume is usually no more than 1ul. The maximum injection volume depends on the internal volume of the liner. 2, split injection sample is divided into two after vaporization. Enter part of the column, the other part being split vent. In this case, the sample determines the flow and volume injection liner transfer rate from the mouth of the main split vent. Column flow is negligible. In order to improve the separation column, it may adopt fast injection manner. Split injection can be used in all of the capillary column (Neijing from 100 microns to 530 microns), split injection mode of maximum injection volume is about 1ul. 3, split / splitless initial splitless process, vaporized sample is transferred to a column in. Speed ??and efficiency of this process is determined by the volume of traffic and liner capillary column. Splitless injection mode is generally usually with large volume injection mode, the injection volume up 5ul no problem. These samples due to overload liner does not directly into the column, so the feed rate to be very small, typically 1ul / s.
