Comparison of GC/time-of-flight MS with GC/quadrupole MS for halocarbon trace gas analysis

High through put analysis of MALDI time-of-flight MS/MS and LCMS/MS data

Analysis of trace metals in comparison of laser-induced breakdown spectroscopy with LA-ICP-MS

Laser-induced breakdown spectroscopy (LIBS) and LA-ICP-MS (laser ablation inductively coupled plasma mass-spectrometry) were used for the detection of trace metals in a solid matrix consisting of KBr and two oxides. The results of both methods were compared to investigate the strengths and weaknesses of both methods. Most difficulties for quantification of LIBS data are related to matrix effect...

Comparison with MS-GFDB

Since the published MS-GFDB did not support variable PTMs at the time that this research was carried out, both MS-GFDB and PEAKS DB were run without specifying any variable PTMs. The other parameters, including the fixed PTMs, remained the same as described in the results section. The results are shown in Figure S2 for CID and Figure S3 for ETD datasets, respectively. Note that the removal of t...

Validation of an UHPLC-MS/MS method for simultaneous analysis of 11 mycotoxins in wheat flour Using Immunoaffinity column

This study focuses on optimization and validation of an Ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for simultaneous analysis of 11mycotoxins: Aflatoxin B1, T-2 Toxin, Ochratoxin A, Deoxynivalenol and Zearalenone in wheat matrix. Sample extraction and cleanup procedure is based on a single extraction step using acetonitrile/water/acetic acid mixture...
