Optimizing Split Injections

When performing a split injection, there are several considerations to keep in mind to improve the quality of your chromatography. But what should you change and why?
In this Restek Tip, we’re going to show you how to optimize your split injections. We’ll start with liner selection, before discussing the importance of split ratios. Next, we’ll focus on optimizing the inlet temperature, and finally, the initial oven temperature.

[@justforentertainment74]

Thank you for explaining

[@RestekCorp]

You're welcome

[@hanumantharaorao5874]

Thank you sir

[@meme2403]

You talk about the initial oven temperature, does this mean that the separation was carried out in temperature programming mode? Tank you.

[@RestekCorp]

Generally yes, but it doesn't need to be.

Congratulations for the video, but I don't understand how a pulsed split injection can have the liner with increased pressure if the injector outlet opens?

[@RestekCorp]

The pressure controls of the GC system are designed to handle these pressure changes. So while there is still flow going through the column (and out the split vent, septum purge, etc.) pulsed injection allows users to temporarily elevate the pressure in the injection port.
