This role involves; •Organic synthesis of the building blocks and templates. •Characterization of the three-dimensional structures of adducts (NMR, UV-Vis, LCMS ... WebThe ion at m/z 458 was most likely the NH4+ adduct, which is not an uncommon thing in ESI. If you look hard (review EICs for the relevant ions), you probably will also see Na+ (m/z 463) , K+ (m/z 479) adducts . And this may further support the NH4+ adduct annotation. You were right, Hanghui Liu, the ion adduct 458 came from NH4+.

The cone voltage provides a means to reduce the incidence of ion clusters (declustering potential), which will reduce the complexity of resulting spectra and reduce spectral noise. Note that your voltage settings may be transferable to another instrument. WebDocument Library.
