Identification and characterization of impurities in an insecticide, commercial chlorantraniliprole using liquid chromatography-tandem mass spectrometry
CONCLUSION: The quality and impurities of CAP, a popular insecticide, must be assessed and described for its efficacy and safety. In this study, four impurities of CAP were detected using HPLC and successfully characterized using LC-HRMS, LC-MS/MS, and NMR data. The method is useful for verifying the purity of CAP as well as helping in the identification of its possible impurities.PMID:38456250 | DOI:10.1002/rcm.9729 (Source: Rapid Communications in Mass Spectrometry : RCM)

A statistical approach to system suitability testing for mass spectrometry imaging
CONCLUSIONS: This study is the starting point for addressing an important issue and will undergo future development to improve the efficiency of the protocol. Ultimately, this work is the first of its kind and proposes this approach as a proof of concept to develop and implement universal QC/SST protocols for a variety of MSI platforms.PMID:38456255 | DOI:10.1002/rcm.9725 (Source: Rapid Communications in Mass Spectrometry : RCM)

A rapid method for the determination of stable hydrogen isotope ratios of acetic acid in vinegar
CONCLUSIONS: A rapid method was developed for identification of different sources of acetic acid. These different sources of acetic acid exhibited significant hydrogen isotope distribution characteristics. Additionally, it was observed that the carboxyl hydrogen of acetic acid exhibited facile exchange with water. In future investigations, we aim to mitigate this interference.PMID:38419561 | DOI:10.1002/rcm.9718 (Source: Rapid Communications in Mass Spectrometry : RCM)

Gas-phase F-atom migration reaction of deprotonated N-fluoroarenesulfonamides
CONCLUSION: To fully explain the gas-phase reaction mechanism from ArSO2 NF- to SO2 F- , we studied the HR-ESI-MS/MS of deprotonated ArSO2 NHF and also performed theoretical calculations. Both results confirmed that ArSO2 NF- first underwent Smiles rearrangement to yield intermediate I (INT1) ArNFSO2 - , and then the F-atom of ArNFSO2 - migrated from the N-atom to the S-atom to form intermediate II (INT2) ArN- SO2 F, which finally dissociated to SO2 F- at m/z 83 with loss of a neutral nitrene (ArN). All these results showed that the formation of the product ion SO2 F- from ArSO2 NF- was a common and intrinsic gas-phase rea...

Desorption electrospray ionization mass spectrometry imaging of latent fingerprints revealed by Oil Red O
CONCLUSIONS: DESI-MS has demonstrated imaging compatibility with the application of ORO used to enhance latent fingerprints on paper and could also enable chemical profiling in natural fingermarks. In addition, MS images of ORO impurities were of higher quality than optical ones for fingerprints revealed on colored paper.PMID:38420652 | DOI:10.1002/rcm.9724 (Source: Rapid Communications in Mass Spectrometry : RCM)
