Splitless injections excel at trace analyses, but to get to get the most out of a splitless analysis, it’s important to optimize your system. But what should you optimize and what are the benefits?
In this Restek Tip, we’re going to show you how to optimize your splitless injections. We’ll start with liner selection, before discussing the importance of the splitless hold time. Next, we’ll focus on optimizing the inlet temperature, and finally, the initial oven temperature.

I'm careful if I can ask here, but is it possible to analyze isophthalic acid by GC-MS? I have been having a tailing problem for a month. I will buy all the products you recommend. Somebody help me T^T

Tailing happens when the analyte of interest retains in the column. How the oven is programmed, gas flow rate, or the column used could impact your acid. You might need to look into different columns since you are dealing with aromatic acids, like Chromaton N-AW-HMDS with 5% Apiezon L column.
