Split vs. Splitless Injection

[@bobbysumarso5965]

nice, rarely i got information i need with these kind of videos but this one is actually pretty good

[@blackyme2889]

i wish they taught us like this in pharmacy ,,, thank you man you helped me alot

[@RestekCorp]

You are most welcome!

[@اشرفمصطفىكاملفعص]

You're the bestest in explanations

[@okyoros]

Thank you for such wonderful explanation.

RESTEK is a Backbone to us

[@RestekCorp]

Thank you!

[@giuseppezedde4553]

Your videos are a masterpiece! They are truly perfect, I congratulate you. I would be really grateful if you made a video describing all the steps of a gas chromatographic analysis. Thank you very much!

[@RestekCorp]

We'll have some more videos coming very soon looking at some details of both split and splitless injection.

Restek are beasts when it comes to GC.

Great Explanation 💯💯

[@jabutosu]

Very useful

[@ramonverduzco3522]

In the diagrams of the inlet it appears that the column protrudes more into the liner for splitless injections versus split injection. Is this correct or am I taking too much from the diagrams? Thanks!

[@RestekCorp]

Column installation distance should not change between split and splitless.

[@aartigupta2390]

In splitless type, why was the vent opened after sometime?

[@RestekCorp]

In splitless, the vent is opened to purge any remaining material from the inlet. Accordingly, it is important to set the time for when that happens correctly. You should allow time, based on flow rate and liner volume, for 1.5 to 2 liner volumes to pass through the inlet, then open the split vent to purge any remaining material.

If you could make videos for other injection methods Thanks

[@RestekCorp]

We've some more videos on optimizing split and splitless that are in development. Any particular injection methods you are interested in?

[@halamboha50]

@@RestekCorp Thanks for your quick response and I appreciate it. A lot of sample introduction methods in GC can be used such as: 1- Thermal desorption (single vs multi/ two stage) 2- Solid-phase microextraction (SPME)/ Headspace 3- Purge and Trap 4- Cold On-Column Injection 5- Programmable Temperature Vaporizing (PTV) Injection 6- Gas Sampling Valve These are some other sample introduction methods other than split/split injection method. Thanks

[@RestekCorp]

We have several videos in development for SPME right now, and most of the rest of your list are already on our idea list, but we will add the others. Thank you!

How to calculate split rato based on column and split flow.

[@RestekCorp]

It is generally expressed as a ratio of split flow : column flow, so if you have 100 mL/min of split vent flow and 1 mL/min of column flow, you have a split ratio of 100:1.

How gas flow is in volume/time? How can we measure gas volume when it flows?
