Spectrometer Definition and 161 Threads

I'm designing my lab and so I want a spectrometer to investigate reaction kinetics eh. I am looking for a data logging spectrometer that can keep the reaction at constant temperature. My teacher is probably going to buy it. Does anyone know what company makes good spectrometers? About a...

The electric field between the plates of the velocity selector in a Bainbridege mass spectrometer is 20 V/m, and the magnectic field in both regions is 10 T(out and inside the spectrometer). A stream of singly charged selenium ions moves in a circular path with a radius of 1 m in the magnectic...

hey im looking for a conceptual question regarding the mass spectrometer, any concepts that are not usually mentioned in textbooks thanks !

[FONT="Comic Sans MS"]1.Some data obtained from the mass spectrum of a sample of carbon are given below. Ion 12C+ 13C+ Absolute mass of one ion/g 1.993 x 10-23 2.158 x 10-23 Relative abundance/ % 98.9 1.1 Use the data...

Hi, My Question: Suppose the electic field between the two electric plates in the mass spectrometer is 2.48 x 10^4 V/m and the magnetic fields B=B'=0.68 T. The source contains carbon isotopes of mass number 12,13,14 from a long dead piece of tree(To estimate atomic masses multiply by...

In the Plenary Session #1 of the Space Nuclear Conference 2005, Samuel C. C. Ting gave a presentation on the AMS-02, the second "Alpha Magnetic Spectrometer." The first, AMS-01, flew aboard the Space Shuttle during Mission STS-91. The AMS homepage is -...

Hey Everyone, I just got to my last homework question, and well I got a bit stuck. An ion source contains two isotopes of magnesium ( 24Mg, 25Mg). These ions travels undeflected through the velocity selector (B=0.850T, [E]=4.60x10^5V/m) of a mass spectrometer. If both isotopes are singly...

Can someone estimate how sensitive a spectrometer has to be in order to measure the velocity spectra of Io through a 0.7m focal length refractor telescope (radius 70mm) of during optimal conditions? :smile:

Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 x 10^-25 kg. The ions are accelerated from rest through a potential difference of 1.40 kV. Then, a 0.600 T magnetic field causes the ions to follow a circular path. Determine the...

Here are two chem questions that I can't figure them out...please give me some hints on solving them 1.) Ionic compounds( not simple molecular) can also be analyzed by mass spectrometer. Syggest how the sample can be vaporized. It can't be heating I think. 2.) Elements X and Y form a...

Given: A proton is accelerated up to KE before it exits into a magnetic field and is deflected. Question: What voltage battery is required accelerate the proton to that energy? So I use U = qV the question is.. what is Q.. is q the charge of the proton being accelerated through the...
