WebThe analytical advantages of matrix assisted laser desorption ionization TOF MS have been demonstrated for more than 25 years. With inherent advantages including its speed (time to results) and application flexibility, the convenience and effectiveness of MALDI-TOF MS is magnified by virtue of its low sample volume requirements and broad sample content … WebMALDI STANDARD OPERATION PROTOCOL This is a guide to using the MALDI-TOF for those who have received training. If you have any questions or problems whilst using this instrument please contact a member of the Mass Spectrometry Facility Staff. Note: all users must obtain training from a member of the mass spectrometry staff before using the
MALDI methodology is a three-step process. First, the sample is mixed with a suitable matrix material and applied to a metal plate. Second, a pulsed laser irradiates the sample, triggering ablation and desorption of the sample and matrix material. See more In mass spectrometry, matrix-assisted laser desorption/ionization (MALDI) is an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal fragmentation. It … See more The matrix consists of crystallized molecules, of which the three most commonly used are sinapinic acid, α-cyano-4-hydroxycinnamic acid (α-CHCA, alpha-cyano or … See more The laser is fired at the matrix crystals in the dried-droplet spot. The matrix absorbs the laser energy and it is thought that primarily the matrix is desorbed and ionized (by addition of a proton) by this event. The hot plume produced during ablation contains … See more The term matrix-assisted laser desorption ionization (MALDI) was coined in 1985 by Franz Hillenkamp, Michael Karas and their colleagues. These researchers found that the See more There are several variations of the MALDI technology and comparable instruments are today produced for very different purposes. From more academic and analytical, to more industrial and high throughput.
