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+.
