Any Mad Scientists among us?

I like collecting cool stuff to experiment with.
I've recently acquired a Mass Spectrometer for FREE.

It has a turbomolecular pump in it. (60,000+ rpms)

I could possibly use it, I have a suspicion there was a lot of Boron in my last delivery of steel. :lol: :lol: :lol: :lol:

I am challenged enough operating a bathroom scale recording my own mass with out manipulating the data :D

And if you buy a collider I am reporting you to your Homeowners Association :o

I use a mass spectrometer in my day-to-day work. It, too, has a turbo-molecular pump, capable of creating vacuum down to less than 1.0E -06 torr. (I'd have to pull the spec to tell you the actual ultimate partial pressure, but the number I gave is an underestimate, if anything.)

The spectrometer tube is tuned specifically for helium, but I know how to tune it myself, and can make it register other ions, though the need does not arise in my work. I just like knowing how.

Damn, vacuum work sucks. :lol: :lol: :lol: :lol:

I used an old Alcatel unit for years testing SST vacuum plumbing for the semiconductor industry, not exactly mad scientist material though... :|

I typically use Agilent/Varian products. I'm most accustomed to the 979, but we've recently acquired a 959, which is far more "manual" in nature, and I'm interested to see what I can do with it, in light of the manual adjustments I can make to get it to perform in the manner I need. It's rated for less sensitivity than the 979 by a factor of 100, but in the nanoliter range, that's less significant than it sounds.

Werkspace, does your freebie mass-spec come with or require a roughing pump or fore pump?

I guess I should look at the youtubes you shared...
[Edit] Ah, these are videos on operating theory, with which I'm already quite familiar.

My Mass Spectrometer is a Varian 1200.
(I also have a spare turbomolecular pump)
I've owned the roughing pump for several years.

I assume, then, you're familiar with the major suppliers for various components, consumables, etc. such as Ideal Vacuum Products and Key High.

Though should not ASS U ME...
(These are recently acquired toys.)
I'm going to need some time to put this project in motion.

I get most of my accessories, fittings, etc. from Ideal,

http://www.idealvac.com

Their catalog (at least the hard copy) has lots of useful data and theory.
