What is the function of ion collector in dempster's mass spectrometer?

The collector is a detector, where charged mass fragments are counted, as they strike it. The collector/detector passes an electrical signal, proportional to the number of charged ion incidences, to counting electrical circuits, which measure the current strengths, and sum them per mass weight. The output shows, in a serial, numbered fashion - the relative strengths, or abundances, of ions detected for each mass weight.
The Dempster collector, being an early mass spectrometer, did not have a mass filter, and collected both positive and negative ions. Later developments in mass spectrometry focused on positive ion collection, as being most analytically useful, because the fragmentations could be more easily predicted. The mass filter was invented, (by?), which actually filters out negative ion radiation; and was implemented to purify the collector input into positive ions.

What is the function of an ionization chamber?
the ionization chamber ionizes atoms into ions in the in the mass spectrometer
What instrument measures atomic mass?
A very accurate mass spectrometer is needed.
How do you distinguish isotopes by mass spectrometer?
Isotopes (of the same element) have different mass, this is measured by the mass spectrometer
How can isotpes of carbon be separated?
Mass spectrometer. (and centrifuges)
Why you keep low pressure in mass spectrometer?
prevents collisions

How does a spectrometer work?
The mass spectrometer is an instrument which can measure the masses and relative concentrations of atoms and molecules. It makes use of the basic magnetic force on a moving charged particle. After ionization,acceleration and selection of single velocity particles the ions move into a mass spectrometer region where the radius of the path and thus the position on the detector is a function of the mass.
What is the device used to determine atomic masses?
spectrometer
How do you determine the mass of atom using mass spectrometer?
Actually in mass spectrometer the isotopes of an element are separated by applying magnetic field.Each isotope is then compared with carbon-12 to get the atomic mass of that isotope.
What rhymes with mass spectrometer?
Das Volkswagen?
Is difference of mass number is calculated by electron microscope?
no, the mass spectrometer.
How did the mass spectrometer advance the periodic table?
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
What is used to measure amounts of isotopes?
mass spectrometer
What matter is a mass spectrometer used to get information from?
plants
How can isotpes of carbon be separated?
Mass spectrometer. (and centrifuges)
