Sample sprayer

Spray indexing permits acquiring sample and lock-spray data in separate
data channels, and the baffle design ensures negligible cross-talk between the
two sprays. The lock-spray data are used to calculate a correction factor for
the mass-scale calibration, which is then applied to the sample data, providing
exact-mass information.

You can use the NanoLockSpray source with different NanoFlow sprayers.

The LockSpray sprayers for the LockSpray source and NanoLockSpray source
operate as part of the instrument's IntelliStart Fluidics system. Fitted with a
500-µL pump, the LockSpray sprayer operates at 0.5 µL/min. You must choose
the concentration of the lock-spray reference solution that gives a suitable ion
intensity.
