LockSpray Exact Mass Ionization Source. Make exact mass measurements easy.
The LockSpray dual electrospray ion source optimizes the co-introduction of analyte and lock mass compound directly into the ion source, providing authenticated exact mass measurement in MS and MS/MS modes to within 5 ppm RMS mass accuracy (3 ppm for Xevo QTof MS and 1 ppm for Xevo G2 Tof series, Xevo G2 QTof series and SYNAPT G2 series).
