Is a Homemade Quadrupole Mass Spectrometer Possible?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of building a homemade quadrupole mass spectrometer, with participants sharing their experiences and insights related to constructing various types of mass spectrometers, particularly time-of-flight (TOF) and quadrupole designs. The conversation includes inquiries about resources, schematics, and the challenges associated with amateur scientific instrumentation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses interest in building a homemade TOF mass spectrometer and seeks information on similar amateur projects.
  • Another participant mentions having found various online resources related to TOF mass spectrometry and shares links to these resources.
  • A participant notes the rarity of amateurs constructing such scientific instruments, particularly in Europe, and references notable examples from the USA.
  • There is a suggestion that a quadrupole design might be less challenging for home construction compared to a TOF mass spectrometer.
  • Another participant expresses interest in constructing a quadrupole mass spectrometer and requests practical suggestions for getting started.
  • One participant proposes a different approach involving the analysis of light emitted from objects, suggesting a method for breaking down color emissions based on temperature.
  • A later reply questions the simplicity of building a quadrupole detector compared to a TOF detector, highlighting the relative ease of constructing a TOF setup if vacuum and electrical components are managed properly.

Areas of Agreement / Disagreement

Participants express varying opinions on the relative difficulty of constructing TOF versus quadrupole mass spectrometers, indicating that there is no consensus on which design is easier for amateur builders.

Contextual Notes

Participants reference specific individuals and projects, but the discussion lacks detailed technical specifications or established methodologies for building the devices discussed.

Who May Find This Useful

Amateur scientists and hobbyists interested in constructing mass spectrometers or other scientific instruments may find the shared experiences and resources valuable.

Hi,

I'm a french (old) amateur scientist developping an homemade TOF mass spectrometer and I'll be pleased to know other amateur realizations in this area. I've found an homemade TEM on the web, and that's all. If someone has already tried to built such a device or know a site where I can find interesting details it will be of great help for me. Thanks by advance.

Good afternoon,

I have seen some schematics on the web. A TOF mass spectrometer is a instrument, that separate the ions in time-of-flight, and measure the mass. Other words, I've found TOFMS
(Time-of-flight mass spectrometry) on the web. Please see this web sites:

The first time I hear about an amateur who think of building a TOF. It's exciting
 
Hi,

Yes it's not so frequent to find amateur developping such scientific instruments, and may be especially in Europe. But in USA there are a lot of other "crazy" guys who built such equipments and I think for example to Fred Niell who has built an homemade linear accelerator and a really wonderful cyclotron !
 
How about a quadrupole design - I think this would be less challenging for home - construction.
 
I too am interested in constructing amateur scientific instruments. I found Fred Niell's accomplishments truly amazing. A quadrupole MS would come in great use and if anyone has some suggestions on how to get started in practical terms, I am interested as well as a bunch of others out there. Where did you find the TEM on the web?

Thanks.
 
Before you jump into this, all you need is a facy camera. break down the the oscillations of light emitted from the object -at a certain temp- by the color emitted, ie what color it is.

Start with a picture, (internet ?) -break it down according to color (microsoft paint), -break it down according to a given temperature (heat picture, if you want to be scientific)

start from there.

I don't know... The tube might be simpler, but it's a lot easier to build a TOF detector than quadrupole detector. With TOF, if you managed the vacuum tube and the anode, all you have to do is hook up the cathode to an oscilloscope and that's basically your TOF spectrum.
