GC-MS update (04/15/21)
It's a modern, high-resolution, accurate-mass spectrometer, that is, frankly, much better than the GCMate in almost every respect. It is however not set up for open access, so Tony and I will have to take your samples there and run them for you.
Here is what to do if you want a GC-MS analysis:
Get autosampler vials from the AV400 prep table in B-73
Prepare your sample
Use a low-boiling, apolar solvent of high purity
Avoid diethyl ether and THF if you can as your bulk solvent. Small amounts are OK.
Chlorinated solvents are fine for MS (Don't use them for GC-FID)
Concentration should be less than 1 mM (~100 µg/ml). Calculate and measure! Don't guesstimate
Total sample volume should be between 0.5 and 2 ml. If you want to make smaller samples, ask us for a microvolume insert.
Label your sample with NetID and sample identification
Prepare an information sheet
Put your sample(s) and the information sheet(s) in a Ziploc bag and put the bag in the carboard box on the AV400 prep table in B-73
We will collect the samples and take them to Biotech a few times per week.
