- Abstract
An atmosphere pressure ion mobility spectrometer is described. Both electrospray and corona discharge ion sources were used. Increased up to 100 resolving power allows obtaining higher selectivity and potentially widens application area. Satisfactory reproducibility of measured reduced mobility is required for improving reliability of identification including interlaboratory reproducibility of measured reduced mobility. Results of measurement were shown for the samples containing compounds proposed earlier as standards, those were measured in remote laboratories. Measured reduced mobility for 2,6-di( tert-butyl)pyridine amounted 1.48 cm/V · sec for the measurements where corona discharge was used, and 1.46 cm/V · sec for the measurements, where electrospray ionization was used. Both values are in a good agreement with a value 1.48 cm/V · sec obtained earlier on the previous version of the instrument. Values of reduced mobility calculated by results of measurements accomplished in Munich for tetraethylammonium iodide, tetra-pentylammonium iodide and tetraoctylammonium bromide amounted correspondingly 1.77, 1.10, and 0.64 cm/V · sec when electrospray ionization was used. The data are in a very good agreement with the values obtained earlier on the previous version of the instrument in remote laboratory.
