I'm running through needles faster that toilet paper. My Samples are dried and derivatised with BSTFA:TMCS:Pyridine (5:1:1 ratio). I used to use hexane and pyridine (two separate washes), but now uses IPA:Acetone (1:1 ratio) with slightly better (albeit still unsatisfactory) results.
Also, we seem to get better mileage during the cold-dry months, but the problem is aggravated during the warm (very humid) summers in central South-Afirca.
Please advise
P.S. Please also indicate your preferred wash method (amount of washes before and after injections)
