An isotope ratio mass spectrometer measures the ratios of different isotopes of elements, providing information about a sample’s age and origin. Samples are prepared and introduced into the instrument, where they are converted into a gas and ionized before being separated based on their masses. The resulting proportions of isotopes can be calculated and used […]
Accelerator mass spectrometers use magnetism and high voltage to measure radioactive elements. They are used in archaeology to date artifacts and in medical diagnostic testing. The device has a magnetic separator and a tandem accelerator that accelerates particles and directs them to a detector. An accelerator mass spectrometer is a laboratory device that uses a […]
Electrospray mass spectrometry (EMS) is used to study large molecules without fragmentation. A pure macromolecular sample is dissolved in a solvent system, injected into a high voltage electric field, and studied. EMS coupled with time-of-flight analysis and collision cooling reduces fragmentation. Isotopes can affect EMS determinations, making monoisotopic samples preferable. A mass spectrometer (MS) is […]
A gas mass spectrometer detects the concentration of elements in known and unknown samples by sensing the deflection of charged ions in a magnetic field. Inorganic analysis produces a characteristic spectrum, while organic analysis is more complex. In a gas chromatography mass spectrometer, compounds are separated by gas chromatography before being sent to the gas […]
Ionization mass spectrometers are used in various fields to identify the chemical composition of a substance. They work by charging particles in a sample and sorting them by mass to create a spectrum. They are used in geology, meteorology, space exploration, medical research, and industrial applications. They can identify chemicals in the human body, study […]
A tandem mass spectrometer is used to measure the mass of molecules and identify compounds in a sample. It can fragment molecules and ions to identify proteins and other organic substances. The detector tracks ion activity and creates a graph to show the molecular mass and amount of each substance in the sample. Different experiments […]
The mass spectrometer determines chemical composition by ionizing and accelerating a sample through a chamber with a magnet that bends ions towards a detector. Different types of ionization are used, and the technique can detect isotopes and provide insight into chemical ratios. A mass spectrometer is a device that can be used to determine the […]
