MALDI TOF mass spectrometers (matrix-assisted laser desorption/ionization/time-of-flight) are amongst the most popular mass spec instruments in biology. They combine two technologies, the “soft” MALDI ionization source and the TOF mass analyzer. The latter measures an ion’s mass-to-charge ratio (m/z) by measuring the time it takes to reach a detector. The former volatilizes and ionizes those molecules using a laser, a target, and an organic compound called a matrix. In MALDI, a sample (for instance, a collection of tryptic peptides) is mixed with matrix, spotted and dried (crystallized) on the surface of a metal target plate. Upon irradiation with laser light, the matrix absorbs the energy and converts it to heat, which then causes the sample to ionize and explode off the plate into the mass analyzer. MALDI TOF mass spectrometers come in two basic flavors, MALDI TOF MS and MALDI TOF/TOF MS; the latter enables tandem MS (MS/MS) studies.

| Description | Inquire | Inquire | Through innovative instrument design, the space-saving linear MALDI-8020 achieves performance specifications similar to those of larger, more expensive MALDI-TOF models but in a significantly smaller footprint. The MALDI-8020 improves laboratory efficiency and accelerates analysis through a newly Through innovative instrument design, the space-saving linear MALDI-8020 achieves performance specifications similar to those of larger, more expensive MALDI-TOF models but in a significantly smaller footprint. The MALDI-8020 improves laboratory efficiency and accelerates analysis through a newly designed load-lock system for rapid sample target introduction and a solid-state laser for fast data acquisition speeds. Using linear time of flight, this compact MALDI-TOF system enables low-level detection of proteins, peptides and polymers, among other analytes. In addition, it easily accommodates standard laboratory workflows such as peptide mass finger printing for simple protein ID confirmation, in-source decay (ISD) and polymer distribution analysis.
Features: - Compact benchtop design
- Rapid loading and acquisition
- Automated source cleaning
- Integrated barcode scanner
