Energy loss of 40Ar in Au: Comparison of TOF-E and TOF–TOF method

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
Abstract Energy loss of 40Ar ions in Au has been measured using two methods: TOF-E and TOF–TOF. The two methods are compared and discussed. The final results cover energy range 2–445 MeV (0.05–11 MeV/u) and give satisfactory agreement with SRIM 2003 predictions. Statistical error of the data is at the level of 1–2%.

Off-Line Coupling of High-Resolution Capillary Electrophoresis to MALDI-TOF and TOF/TOF MS

Journal of Proteome Research, 2002
High-resolution capillary electrophoresis has been coupled to MALDI-TOF and TOF/TOF MS through off-line vacuum deposition onto standard stainless steel MALDI targets. This off-line approach allowed the decoupling of the separation from the MS analysis, thus allowing each to be independently optimized in terms of time.

An Inexpensive, simple calibration method for MALDI TOF/TOF systems

Journal of Mass Spectrometry, 2019
AbstractThe array of analytes that can be measured by MADLI MS has created an equally vast range of calibration mixtures. The inherent problem with this is that acquiring all of them at commercial rates can be prohibitively expensive. With this in mind, we have created a low‐cost alternative to the most commonly used peptide calibrants.We were able to ...

A novel MALDI LIFT-TOF/TOF mass spectrometer for proteomics

Analytical and Bioanalytical Chemistry, 2003
A new matrix-assisted laser-desorption/ionization time-of-flight/time-of-flight mass spectrometer with the novel "LIFT" technique (MALDI LIFT-TOF/TOF MS) is described. This instrument provides high sensitivity (attomole range) for peptide mass fingerprints (PMF). It is also possible to analyze fragment ions generated by any one of three different modes

ToF‐SIMS of polyphosphate glasses

Surface and Interface Analysis, 2012
The increasing interest in phosphate glasses is due to the fact that they are considered to be bioactive functional materials in applications such as hard and soft tissue engineering and also that they possess interesting optical properties.

Amino Acid Analysis by Means of MALDI TOF Mass Spectrometry or MALDI TOF/TOF Tandem Mass Spectrometry

2011
Here we describe two different AAA protocols based on application of matrix-assisted laser desorption ionization time-of-flight (MALDI TOF) mass spectrometry (MS). First protocol describes a MALDI TOF MS-based method for a routine simultaneous qualitative and quantitative analysis of free amino acids and protein hydrolysates.
