This study demonstrates that an accurate precursor mass is particularly important for the nLC-MS/MS analyses of less-specific proteolytic digests. A potential gain of approximately one-third additional peptides. The recently established coupling of a MALDI-type ion source to a linear ion trap and an orbitrap mass analyzer offers high-accuracy mass measurements compared to common MALDI-TOF/TOF instruments. Contrary to MALDI-TOF/TOF, the fragmentation of peptides in the new hybrid mass spectrometer is less efficient due to the generation of predominantly singly charged ions by the MALDI process.

A MALDI LTQ Orbitrap XL Pro mass spectrometer (Thermo Scientific, San José, CA, USA) was employed for data acquisition. For MSI experiments with LTQ-Orbitrap MS, tissue sections deposited on non-conductive (Superfrost plus) slides could be used, as previously described Here we mitigate this problem by use of laser-induced post-ionization (MALDI-2) and by adapting a t-MALDI-2 ion source to an Orbitrap mass analyzer. We demonstrate the crucial sensitivity and accuracy boosts that are achieved with this combination by visualizing the distribution of numerous phospho- and glycolipids in mouse cerebellum and kidney slices, and in cultured Vero B4 cells.

The MALDI LTQ Orbitrap™ provides fast, reliable, confident and complementary protein identification and enables for various analytical approaches to localize post-translational modifications. Outstanding mass accuracy and high sensitivity make the MALDI LTQ Orbitrap a superior alternative to traditional MALDI-TOF systems. The MALDI LTQ Orbitrap offers: High throughput analysis of in-gel. Experiments were performed on a Thermo Scientific MALDI-LTQ-Orbitrap XL hybrid mass spectrometer (Thermo Fisher Scientific, Bremen, Germany) in which a linear ion trap is coupled to an Orbitrap™ mass analyzer. The MALDI source contains a nitrogen laser operating at 337.1 nm wavelength with a beam diameter of about 80 ∗ 100 μm 2

The LTQ Orbitrap capabilities were extended not only by enhancing C-trap abilities but also by improvements in the front-end. One of the most important extensions became a matrix-assisted laser desorption and ionization (MALDI) source operating at reduced pressure. Trapping in gas minimizes issues related to unimolecular dissociations due to. The MALDI-LTQ-Orbitrap XL mass spectrometer is a high performance instrument capable of high resolution and accurate mass (HRAM) measurements. The maximum m/z of 4000 precludes the MALDI analysis of proteins without generating multiply charged ions. Herein, we present the study of HRAM laserspray ionization mass spectrometry (MS) with MS/MS and MS imaging capabilities using 2. Orbitrap mass spectrometers deliver a total possible maximum resolution (FWHM) of 1,000,000 at m/z 200 and a sub-1 ppm mass accuracy in a single compact and easy-to-use instrument. These high-resolution accurate-mass systems detect a wide range of compounds and small molecules during both targeted and untargeted analyses, without losing selectivity or sensitivity. Simply put, when it comes to.

Chapter 2 MALDI2-Orbitrap. 2.1 Introduction. The sensitivity of MALDI is restricted mainly by two factors: (1) low ionization efficiency. Less than 1 out of 1000 desorbed molecules is on average ionized; and (2) strong ion suppression effects, particular in positive ion mode. A laser-based post-ionization (PI) approach is introduced to overcome these limitations (Soltwisch et al. 2015).

MALDI is a soft ionization technique to create ions with minimal fragmentation by using a laser energy. In TOF, the protonated ions are accelerated by an electric field to make an ion have the same kinetic energy as any other ions that have the same charge. The velocity of the ion depends on the mass-to-charge (m/z) ratio and the time that takes for the ion to reach a detector is measured. With this proposal, we are requesting funds to acquire a MALDI LTQ Orbitrap XL mass spectrometer from Thermo Scientific for bioimaging at the Public Health Research Institute (PHRI), which will be use..
