Brief Description:

HRMS is an analytical technique that is used to determine the masses of organic, inorganic, biomolecules and materials or monatomic ions present in different kinds of samples. HRMS analysis begins by passing a sample into the spectrometer, where it is ionized. For every ionic species which passes through the mass spectrometer, a ratio of charge-to-mass is recorded, usually to four decimal places. This can be compared to theoretical values for the exact masses of different chemical species to determine which atoms and/or isotopes contained in each detected ion. This technique is used across a variety of fields in academic and industry due to its accuracy and ability to discern the presence of multiple chemical species, even at very low concentrations. HRMS is very useful when it comes to identifying unknown compounds and high purity as the results are accurate and more precise.
