why can`t it be a split inlet?
i`m sorry....i`m just learning about it . and i can`t find the answer for this question.
hope someone can help
thanks

yes. thats exactly what the book is saying. So why would you use a splitless injection in that case? Sorry, this is a bit confusing to me.Is the book perhaps referring to the injection of liquid samples which have been produced by solvent extraction of the adsorbent that has been used to trap purged volatiles ? Certainly in that case I would use a splitless injection.

Peter,
The one scenario where this works really well is not trace but higher levels and the need for speed. Trap lots and lots of samples at higher concentrations, extract lots of them with solvent, then rack 'em up and let 'em rip. Not low level work.
Been there, done that..... solvent contaminated site that "inhaled and exhaled" according to barometric pressure fluctuations.
