Fourier transform infrared spectrometry.
The theory and instrumentation for Fourier transform infrared spectrometry are discussed. These instruments measure infrared spectra of the same quality as spectra measured on grating spectrometers in about one thousandth of the time. Their sensitivity advantage for spectra measured in equal times is between a factor of 10 and 100. Commercial spectrometers are now available from nine vendors in...
متن کاملBasics: Fourier Transform Spectrometry
A FT spectrometer is an interferometer. Its historical and most widely known configuration is the Michelson interferometer, shown on Fig. 1. A beam-splitter is used for dividing the light to be spectrally analyzed into two beams. After they have been reflected on two distinct mirrors, the two beams are recombined by the same beam-splitter and sent to a detector. One of the mirrors is fixed, whi...
متن کاملFourier Transform Mass Spectrometry: The Transformation of Modern Environmental Analyses
Unknown compounds in environmental samples are difficult to identify using standard mass spectrometric methods. Fourier transform mass spectrometry (FTMS) has revolutionized how environmental analyses are performed. With its unsurpassed mass accuracy, high resolution and sensitivity, researchers now have a tool for difficult and complex environmental analyses. Two features of FTMS are responsib...
متن کاملDesorption ionization of cesium iodide by Fourier transform mass spectrometry.
Results of studies on the secondary Ion mass spectrometry (SIMS) of CsI by Cs+ ion desorption ionization Fourier transform mass spectrometry (DI-FTMS) are reported. Owlng to the reiatlveiy long time scale of the FTMS experiment, the "anomalous cluster Ion intensity" for the Cs( CsI), + cluster ions observed by Campana is very dlstlnct. A second objective of this study was to evaluate the utilit...
متن کاملFourier-transform mass spectrometry of large molecules by electrospray ionization.
The multiply charged ions produced by electrospray ionization of peptides of molecular masses up to 29 kDa have been successfully introduced into a Fourier transform mass spectrometer of unique capabilities for tandem mass spectrometry, large ion dissociation, and resolution. Electrospray ionization places an unusually high number of charges on a peptide yielding mass/charge (m/z) values of 600...
