I'm looking for advice in putting together a GC system for use in OChem lab. So it should be cheap and easy to run (nitrogen carrier gas...). It does not need high sensitivity, but speed is helpful. Our lab procedures were originally written for use with GOW-MAC's...
Budget-wise, I have to use the Agilent 6850 that I have available: purged packed injector and TCD detector. I want to be able to use the Autoinjector I have with it. I'd still like to get capillary column peak resolution, so I guess I should put in a middle-sized column? ID=20um? 5um?
But I don't know what column dimensions are compatible/advisable with this port/detector combination--I've only ever used split/splitless and MSD, where everything is really small. I don't know what flow rates the TCD works with, so I don't have a point of reference for columns. I don't know what sample volume to aim for if I'm not using a split injection.
Thanks
