Therefore, a volatile buffer should be used if possible (e.g., ammonium acetate, ammonium nitrate). ESI-MS has been used as a detector for FFF analysis of low-molecular-weight ethylene glycol polymers [9], where the effect of different carriers on cluster formation was investigated. ESI-MS has been coupled to size-exclusion chromatography (SEC) in several applications for polymer analysis and other applications where FFF techniques can be successfully used, including proteins, neuropeptides, and DNA molecule segments. Modern ESI-MS has a broad range of flow rates from nanoliters per minute up to milliliters per minute. [Pg.520]

Fig. 3.7. Data (time) domain signal produced by 9.4-Tesla Fourier-transform ion cyclotron resonance mass spectrometer (left), and frequency domain signal (i.e. mass spectrum) after fast Fourier transformation and frequency-to-mass calculation (right). The sample was a mixture of poly(ethylene) glycol polymers used for internal calibration. Fig. 3.7.

Catalyst separation from reaction mixtures has been efficiently carried out by using solvent-resistant nanofiltration membranes [75]. Following an alternative approach to solving this problem a quaternary ammonium salt has been immobilized on a soluble poly(ethylene glycol) polymer support. The supported catalyst thus obtained, soluble in solvents commonly used in PTC such as dichloromethane and acetonitrile, was used in a series of standard reactions under PTC conditions with comparable results to those obtained with traditional PTC catalysts [76]. Moreover, it compares favorably to other quaternary salts immobilized on insoluble polystyrene supports [77]. The catalyst can be easily recovered by precipitation with ethereal solvent and filtration and shows no appreciable loss of activity when recycled three times. [Pg.231]
