I have been running samples lately and things are looking good. Baseline of the GC-FID is solid at 2.7 pA for the instrument background. The only exception was this morning, when I had to fix a leak on the ultra-zero air cylinder (I wonder, where that came from?), which took a while to locate. But now things are working fine, although I am in for a long evening.<\/p>\n

Water quality is fine and blanks are very similar to those in Alert.<\/p>\n
Today I run snow samples collected on June 2 at the Special Studies Trailer (SST), snow layers from 2-6 cm and 36-53 cm from the surface. I carry out headspace and liquid phase measurements in duplicates using a divinylbenzene-coated SPME fibre.<\/p>\n","protected":false},"excerpt":{"rendered":"
