Splitless Carry-Over
Posted: Thu Oct 13, 2005 2:50 pm
Hi All,
When I do splitless injections I use an empty liner which is recommended and recoveries are better than when wool is used.
However I get sample carryover (probably) from sample residue on the bottom of the septa.
I only use 0.2ul hexane at the moment which will not overload the liner.
How can I get around this?
Perhaps I can use a little wool just above the point of sample ejection.
