High-Resolution Native Mass Spectrometry [PDF]
Chemical Reviews, 2021 Native mass spectrometry (MS) involves the analysis and characterization of macromolecules, predominantly intact proteins and protein complexes, whereby as much as possible the native structural features of the analytes are retained. As such, native MS enables the study of secondary, tertiary, and even quaternary structure of proteins and other ...

Secondary ion mass spectrometry imaging of Dictyostelium discoideum aggregation streams. [PDF]
PLoS ONE, 2014 High resolution imaging mass spectrometry could become a valuable tool for cell and developmental biology, but both, high spatial and mass spectral resolution are needed to enable this.

Increased throughput and ultra-high mass resolution in DESI FT-ICR MS imaging through new-generation external data acquisition system and advanced data processing approaches. [PDF]
Sci Rep, 2019 Desorption electrospray ionisation-mass spectrometry imaging (DESI-MSI) is a powerful imaging technique for the analysis of complex surfaces. However, the often highly complex nature of biological samples is particularly challenging for MSI approaches ...

Current Progress in Femtosecond Laser Ablation/Ionisation Time-of-Flight Mass Spectrometry
Applied Sciences, 2021 The last decade witnessed considerable progress in the development of laser ablation/ionisation time-of-flight mass spectrometry (LI-TOFMS). The improvement of both the laser ablation ion sources employing femtosecond lasers and the method of ion ...

Simulation of a Miniature Linear Ion Trap with Half-Round Rod Electrodes
Micromachines, 2022 The miniaturization of ion trap mass analyzers is an important direction in the development of mass spectrometers. In this work, we proposed two models of miniaturized HreLIT with a field radius of about 2 mm based on the existing research on ...

Resolution Ladder for High-Resolution Mass Spectrometry [PDF]
Analytical Chemistry, 2017 High-resolution mass spectrometry has become a key technology in life sciences. Since it is often unfeasible to find pairs of analytes with an appropriate mass difference to actually quantify the resolution experimentally, resolution is usually calculated from the shape of a single mass peak.

Resolution of an intracardiac mass with chemotherapy [PDF]
BMJ Case Reports, 2013 Right atrial intracardiac tumours are uncommonly seen during echocardiography. Our patient presented with primary mediastinal large B-cell lymphoma with intracardiac involvement. The tumour was seen by echocardiography and the extent of the tumour was defined by CT scan of the chest.
