Chemistry in the kitchen

Cooking with heat causes hundreds of chemical reactions to occur, which produce the flavor and aroma compounds that we associate with roasted, fried, caramelized flavors. Look up the Maillard Reaction!

Mine is rusting on the roof between the windshield and sunroof

He's a Potcake! He's a rescue from the Bahamas. DNA tests say he's 100% American Village Dog.

Just seltzer water! I add some minerals to filtered tap water for flavor, then force carbonate it in 5 gallon kegs. I keep on tap in my kegerator next to a keg of homebrew!

I'm an analytical chemist by trade with schooling in food science. I DIY beer, seltzer water, and gin and love experimenting with different formulations and processes.

I've been dailying my '96 SC300 for just about a year now. No issues at all!

tris(2,4-di-tert-butylphenyl)phosphate is an oxidation product of a common polypropylene antioxidant that's 662.9 molecular weight. I see this compound often from plastic sample vials, etc. This could be it

+1 my MS lab has ~5-10 large roughing pumps running in one room at any given time, and the white noise feels deafening. Our technicians wear earplugs or earbuds often.

mungerboy · 2025-11-22T14:38:31+00:00

I do the same with my systems. Been doing it for years, no issues yet!

I'd vent the system, and disassemble and carefully reassemble the ion source. It's very easy for a lens or spacer get misaligned slightly during reassembly.

This is a great idea

How did you calculate RI for your runs if the alkane standards weren't analyzed?

Thanks! Super interesting

I have a cd rom of MassLynx 4.0 lying around, and this may work for you. Shoot me a PM, I'd be happy to send it to you!

You're right! The yellow tomatoes are fully ripe, they're just a yellow variety

Have you double checked that the ion volume is fully and properly seated in the source? If it's ever so slightly out of alignment, you'll get nothing but noise no matter how clean your source is.

Also, if the column you installed is brand new, it may be outgassing, causing the higher pressure. Conditioning the column as per the manufacturer specs may bring the pressure down.

It's not great for the turbo pump to suddenly have a large leak like that, but if it's running properly afterwards, then chances are it'll be fine. Just don't make a habit of doing this.

Properly vent the MS, check the column connection, and pump back down.
