I need to know the scientific name for the small body of air captured under the covers while you sleep. That lovely, warm air probably contains all sorts of interesting molecules you generate or sweat or exude while you're in bed.
For the methods section of a grant (potentially); "we will use a Gilian 800i remote air sampling device drawing air through 4 feet of 3 mil silicone tubing and a MilliporeSigma™ Supelco™
54278U SPE solid phase column. Samples of {INSERT THIS TERM HERE} will be drawn at intervals of two hours with column replacement between each sample."
Because I want to know what molecules exactly my lovely partner/wife/whoever you sleep with is filling that space with so that they are so snuggly first thing in the morning.
@mycotropic
I know nothing about the sampling technologies you mention, but don’t you have to take into account dietary variables and seasonal variations in bedding materials? Are those considered part of the longitudinal scope of the investigation?
@mycotropic
I’m guessing a pathologist has a word for that. I’m a bit skeptical that drawing through an SPE column (dry? or um… moist?) would work, but I’m not a biologist.
#EnvironmentalScience especially quantitative gas phase sampling is hard and, as you pointed out, selecting the appropriate filter for your target molecules is critical to the success of your experiment. Since my target is unknown though I'm considering snagging all of the organics and slapping the sample into LC/LC-electrospray ionization-MS and comparing known and unknown peaks.
@mycotropic
I’m thinking there are environmental chemistry sampling and extraction techniques for gas/aerosol samples, but I only toured that kind of lab.
I would think there’d be some kind of higher diameter filter to increase collection. It might work to also collect a bigger gas volume and concentrate in a lab before identification. Maybe bubble the “bed-atmosphere” (bedmosphere?) through a solvent?
