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.

How do you distinguish isotopes by mass spectrometer?
Isotopes can be distinguished by a mass spectrometer based on their differing atomic masses. The mass spectrometer ionizes a sample, separates the ions based on their mass-to-charge ratio, and then detects the abundance of each ion. The relative abundance of each isotope gives a unique mass spectrum that can be used to identify and quantify isotopes in a sample.
What instrument measures atomic mass?
A mass spectrometer is an instrument that measures the atomic mass of atoms and molecules. It does this by ionizing the sample and then separating the ions based on their mass-to-charge ratio. The resulting mass spectrum provides information on the relative abundance of different isotopes present in the sample.
How can isotpes of carbon be separated?
Mass spectrometer. (and centrifuges)
What is the function of electrometer in mass spectrometer?
An electrometer in a mass spectrometer serves to measure the electric current produced when ions generated from the sample impact a detector. By quantifying this current, the electrometer helps determine the abundance of different ions, allowing for accurate analysis of the sample's mass-to-charge ratio. This data is crucial for identifying and characterizing various chemical species present in the sample.
Which quantity is not required in order to calculate the mass of an ion using a mass spectrometer?
To calculate the mass of an ion using a mass spectrometer, the specific charge of the ion is not required. The mass-to-charge ratio (m/z) is measured directly, allowing for the determination of mass when the charge state is known. However, knowing the exact charge is not essential for calculating the mass itself, as the mass spectrometer provides the m/z value directly.
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?
A mass spectrometer is a device used to determine atomic masses by separating and measuring the mass-to-charge ratio of ions. By analyzing the deflection of ions in a magnetic or electric field, the mass spectrometer can provide accurate measurements of atomic masses.
What is the function of magnetic field in mass spectrometer?
In a mass spectrometer, the magnetic field is used to separate charged particles based on their mass-to-charge ratio. By applying a magnetic field perpendicular to the direction of particle movement, the particles are deflected in a curved path, with the amount of curvature depending on their mass and charge. This allows for the identification and quantification of ions in a sample.

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.

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 the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
Aston's mass spectrograph is a magnetic sector mass spectrometer that separates ions based on their mass-to-charge ratio using magnetic and electric fields. Dempster's mass spectrometer is an early design of a mass spectrometer that used electric and magnetic fields to separate ions based on their mass-to-charge ratio. Aston's design was an improvement over Dempster's, offering higher resolution and precision in analyzing isotopic composition.
