Two examples of application of cryotrapping of volatile hydrides were presented. i. A study of mass spectra of generated selenium hydride, arsane, mono-, di- and trimethylarsane from a DART ionization source coupled with an LTQ- Orbitrap mass spectrometer. ii: The analysis of inorganic and methylated arsenic species for new certified reference materials of river, sea and drinking water, with total arsenic content of 0.2- 1 µg L-1, as an example of the ultrasensitive detection achieved with HG-CT coupled to quadrupole ICP-MS.
