SYNAPT G2 MS fitted with NanoLockSpray source
The following options are available for the spraying capillary:
• Universal NanoFlow nebulizer sprayer.
This option, for flow injection or coupling to nanoACQUITY UPLC, uses
a pump to regulate the flow rate as low as 100 nL/min.
• Borosilicate glass capillary NanoFlow (nanovials).
This option uses metal-coated glass capillaries, which allow the lowest
flow rates. Usable for one sample only, they must then be discarded.
• NanoFlow capillary electrophoresis (CE) sprayer.
This option uses a make-up liquid at the CE capillary tip, which allows a
stable electrospray to occur. The make-up flow rate is less than
1 µL/min.
