Spectrum Search
Spectrum Search

Individual MSn spectra search against mzCloud library to retrieve structural or substructural hits. Query spectrum can be imported from a file.

Structure Search
Structure Search

Find exact structures in the mzCloud library without the hassle of using organic nomenclature. Structure queries can be drawn using the integrated Structure Editor.

Substructure Search
Substructure Search

Find all compounds that contain a particular substructure or fragment using the various search options. A substructure query can be drawn using the integrated Structure Editor.

Tree Search
Tree Search

Confident compound or substructure identification using a tree or subtree search. Spectral trees can be imported from raw files or from an Excel file.

m/z Search
m/z Search

Retrieve spectra and structures that exhibit peaks with a particular m/z value or molecular mass. Accuracy/tolerance interval can be set automatically or by the user.

CompoundName Search
Compound Name Search

Search for IUPAC, trivial, commercial names and synonyms. The text string can be searched anywhere in the name.
