GC - Gas Chromatography - Split & splitless injection Animation HD

Support and hit like and/or subscribe =). Thank you!

A basic video about the concept of the split and splitless injection. Good video for beginners.

Learn the basic concept of Gas Chromatography

1. introduction

2. Mobile phase of GC

3. injection and vaporization of sample (this video)

4. GC Capillary column

5. GC - FID - Flame Ionization

and more to come.

It is actually simple science. Thank you

This is what Mr. Simple Science...Clearly and easily understood...👍

Yes good video. The liner to column interface was one of constant wonder for me, whether it seals against the column and such. Some liners make a decent seal, some do not, depends on the liner.

2:29 shouldn't it be splitflow/column flow?

[uthpalaruvini]

Content is really helpful.one more suggestion.could you please add sound to video.I mean read them

[uchihaangel]

Thank you very much. It 's a good video.

[yulianianisamayapradipta]

what is the meaning if i see in the journal he/she uses split-split less injector. is he/she uses split injector/split less injector/ or both?

[apnacoffeebreak]

Why do we use mostly Split injection in GC?

[mawazeeno]

The video is very helpful, thanks for that. But what do you mean by, make sure the sample does not exceed the liner, please explain this part . thank you ?

Great video to understand. But im having very less quantity of sample, which spilt ratio I have to go?

[shoaibrazakhan]

that really did help . but, according to how u you defined split ratio that ratio of amount of gas flowing to column to that of flowing to split valve, so in that case higher ratio means higher amount of sample to the column that will surely overload the column and consequentially less accurate results will be produced. ratio must be like, ratio of amount of sample sent to split line to that of sent to column. so in this case higher ratio means small amount of sample sent to column. is this so???

I thougt my computer sound settings were off lol

Thank you for smart video, I prepare material about Gas Chromatography can I use this video in my material?
please if you approve I'll be appreciate for you also I'll mention you page in my material.
