Buffer properties spectrometry

Although mass spectrometry offers major advantages when the chromatography is poor and analytes can be identified by their mass spectra, a problem is that dialysate salts can affect sensitivity and stability of the analyte ionization. The extent of this effect depends on the chromatographic properties and ionization source conditions. The inclusion of a divert valve or extraction and cleanup of the analyte from the dialysate is needed to compensate for this problem. The use of water as a dialysis buffer can minimize ion suppression, but can result in... 

Imidazolium ILs easily form micro-emulsions using different surfactants such as long-chain alcohols and the properties of the new micelle-ionic liquid soluhons can be explored in inverse gas chromatography processes [124]. Moreover, ILs have been used as run buffer additives in capillary electrophoresis [125] and as ultra-low-volatility liquid matrixes for matrix-assisted laser desorption/ionizahon mass spectrometry [126]. 

A rather different way of exploiting differences in ion mobilities through a buffer gas is embodied in so-called High Field Asymmetric Waveform Ion Mobility Spectrometry (FAIMS), in which the physical property...
