Description

5800 MALDI TOFTOF is used to obtain the masses of lipids, nucleic acids, peptides, proteins, and polymers ranging in molecular mass from 200 Da up to 100 kDa or more.

For analysis by MALDI, a sample is mixed or coated with an energy-absorbing matrix and then irradiated with a laser beam (typically a Nd:Yag laser).

Singly protonated (positive ionization mode) or deprotonated (negative ionization mode) molecular ions are formed and detected by a time-of-flight mass analyzer.

In addition the 5800 has MS/MS capabilities, aiding in the identification of analytes. The 5800 can also be used for molecular imaging of tissues or materials.
