Split and splitless are the two most commonly used GC injection techniques. While they share some similarities, each is suited to a particular type of analysis. But how do you know which one to use?
In this video, we explore how these two techniques work. We’ll start with split injection, demonstrate the technique in action, and explain what split ratios are. We’ll then switch to splitless injection, show how it differs from split mode, and cover what splitless hold time is and why it matters. Finally, we’ll look at the strengths of each mode to help you choose the right one for your analysis.
