Liner: Volume and temp?
Solvent: Hexane?
Oven program: ?


Here is some information on splitless injections.

The liner volume is 1mL and the temperature (injection temperature) is 250 degrees (celcius). The solvent isn't really relevant (it happens with cyclohexane, toluene, dichloromethane), it gives a wide peak (lasting 30 seconds) and has a massive tail. The oven program depends on the sample.

We have a calibration standard with dichloromethane as solvent, it contains C-8 to C-40 components so the oven program is set; 50 degrees (initial phase, for 5 minutes), rise with 15 degrees/min to 280 degrees (final phase, 30 minutes). After 50 minutes all the components are off the column with this program (all the Carbon components give 'normal' peaks).
The solvent is actually relevent with a splitless injection. You often use a technique,like I described,where you start the column colder than the boiing point of your sovent. The solvent condenses on the walls of the column and the analtes are trapped in that layer of liquid. This is called "solvent focusing",becuase it "focuses" or sharpens your peaks. You then set the inlet to purge after a certain amount of time,which depents in part on how long it takes to for the gas flow to sweep the contents of the liner onto the column. For instance,if your column flow is 1mL/min,and your liner has a volume of 1mL its going to take AT LEAST a minute,perhaps longer. Your fighting two things here,the time it takes to sweep the liner contents onto the column,vs the optimum carrier gas velocity of the column. So you sort of guess at some starting values,and leave the purge time very very long (so you get all of the analyte on the column),then you can set the purge time to clip the tail,and try to optimize it so you get as much analyte as you can,but still get good separation. With a splitless injection,the oven program has a dramatic effect on the chromatography,as do the inlet settings.

With a split injection,so long as you have sufficient temperature for vaporization,inlet settings are pretty much just the split ratio,which when too low give you column overload and poor peak shapes,and when too high,give you poor sensitivity. Oven ramp settings similarly,only cause better or worse separation but its usually obvious which way to go,and column flow (its often better to think of it in terms of gas velocity) alters the number of plates on your column and impacts resolution,and the optimum gas flow is pretty much a constant for those column dimensions. In splitless injections the settings are all much more interdependant. Too short of purge time and you will have poor (or no) sensitivity. Too long and your peak is lost in the solvent tail. The oven temperature controls a lot of chromatography if your using focusing techniques,and if your temperatures are wrong,it simply does not work and your peak shapes and separation is so bad that you may not even be able to find your peaks. The gas flow similarly,effects both what your ramps need to be and what your purge time should be.
