RE: Swipe Testing

["Brian Rees" <brees@lanl.gov>]

There is a paper that addressed the increased efficiency of swipes that 
have been wettedor had H2O added prior to analysis.  If somebody wants that,
 I can get it (it's at home) in a day or two.  The water solubilizes the 
dirt.  Most coctails can handle quite a bit of H2O, so that's not much of 
an issue.  We add 1 ml DI H2O to each smear, then add cocktail and agitate. 
 This brings consistency to quenching concerns.

I'd agree that taking the swipes dry is good practice, and for the reasons 
listed.
