The low pressure prevents false readings due to the presence of other particles.
So that the particles you want to measure can be fired through the spectrometer without hitting the air particles. Basically, it clears the way for them, as otherwise they wouldn't be able to get through. It would be like you running through a crowd. - A2 Chemistry student
A mass spectrometer works by ionizing a sample, separating the ions based on their mass-to-charge ratio, and detecting and measuring the abundance of each ion to determine the composition of the sample.

A liquid chromatograph mass spectrometer separates compounds in a sample by passing the sample through a column that separates the compounds based on their chemical properties. The separated compounds are then ionized and passed into a mass spectrometer, which measures the mass-to-charge ratio of the ions to identify and quantify the compounds present in the sample.

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.
Keeping low pressure in a mass spectrometer is important to ensure that the gas molecules are sufficiently spread out or separated so that they can be analyzed individually. This helps in avoiding collisions between the gas molecules, ensuring accurate mass measurement and ionization processes. Additionally, a low pressure environment allows for improved control over ion trajectories within the instrument.
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.
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.
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.

no, the mass spectrometer.
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
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.
