| MS enables identification of the composition of a compound based on its mass-to-charge ratio. The concept of mass spectrometry consists of fragmenting molecules and creating ions in a gas phase under high vacuum, and then separating the fragments according to their mass-to-charge ratio. In addition, Prosolia's ion soft landing (ISL) technology allows ions of a pre-selected mass-to-charge ratio to be separated and selectively deposited on a proprietary disposable surface in such a manner that the integrity and biological activity of the ionized molecules are retained. |
