CCD Help Pages | Advanced: Mass Search

Mass search returns chemicals based on the monoisotopic masses listed in the intrinsic properties field for each chemical. Masses can be a minimum to maximum range (in Daltons), or a specific mass (in Daltons) plus or minus an error term, in either Daltons or ppm (parts per million).

The search is based on the neutral molecule. It is possible to select various adducts and losses - the mass of the adduct or loss shifts the whole search range. For example a search for the Dalton min-max range 100-110 with the [M+NH4]+ adduct returns results in the range 81.97 to 91.97 to account for the adduct.

Mass Search returns a Chemical List result.
