This third installment of How Dirty Are You?<\/em><\/a> is all about gloves. Outside of solvent compatibility, there is a lot of room for personal preference regarding the type of lab gloves people can use.<\/p>\n\n\n\n

I found 5 different gloves in our lab. The bright green gloves and yellow gloves are the two types most often used by my lab mates. I use the bright green gloves. I work with QuEChERS extracts all the time so I was most interested in background resulting from gloves contacting acetonitrile. I have already investigated the bright green gloves when I was tracking down some peaks in my process blank for a QuEChERS experiment. I was seeing some repeating peaks which were identified as alkanes via GC-TOFMS. Through some further investigation, I was able to confirm that these alkane peaks were from my favorite bright green gloves. That got me thinking about contamination peaks from other gloves…<\/p>\n\n\n\n

What We Did<\/h2>\n\n\n\n

We tested the background generated by the 5 glove types found in our lab by soaking a small piece of glove in 1 mL of acetonitrile for 30 minutes. The samples were tested via GC-TOFMS after the 30 minutes. For relative intensity, a dashed line at the peak height of a 2 ppm PAH standard is drawn on the chromatograms. But you will not see the results until my next blog!<\/a><\/p>\n\n\n\n

Questions<\/h2>\n\n\n\n

1. Which gloves (see below) gave the worst background?<\/h3>\n\n\n\n
