WebSplit/Splitless Inlet Gold Seals for GC. The gold seal forms a leak-free seal with the bottom of the inlet body and column ferrule to minimize both sample contamination and sample … Web1 May 2012 · You can use the same logic for calculating the time needed for an adequate transfer (split-less time) during the injection as well. Instead of using 100 mL/min as the flow rate you will only have the column flow rate of 4.6 mL/min. These calculations have been a good starting point for me in the past when setting up a method from scratch.

Web10 Nov 2024 · The Split/Splitless Inlet (S/SL) can accumulate contaminants when high boiling point and/or high molecular weight compounds are present in the injected sample. … WebSplit inlets were designed to solve this problem; to allow manageable volumes (e.g., 1 µL) of liquid sample to be injected while keeping the amount that reaches the column in the target range. This and the following benefits combine to make the split inlet the most versatile and widely used sample introduction interface for capillary column GC.
