LockSpray source and ionization modes
The LockSpray source uses lock-mass correction to acquire exact mass data.
The sample is introduced into the source through a probe. A lock-spray flow,
containing a compound of known mass, flows through a separate ESI probe
(the LockSpray sprayer). An oscillating baffle allows the sprays to be analyzed
as two separate data functions. The lock-mass correction, calculated from the
lock-spray data, is then applied to the sample data set.
You can use the LockSpray source with the following ionization modes:
•ESI
•APCI
•ESCi
• nanoSpray
