Auxiliary solvent manager
The nanoACQUITY auxiliary solvent manager incorporates two isocratic,
high-pressure pumps that move solvent through the system and provide
steady (pulse-free) solvent flow.
•
Pump A is for sample loading.
•
Pump B is for NanoLockSpray lock-mass addition, two-pump trapping,
and 2D online separation.
In the NanoLockSpray lock-mass addition mode, the pump operates at flow
rates from 0.10 to 5.00
µ
L/min.
Flow control module
The flow control module allows the auxiliary solvent manager to perform
nano-flow chromatography by monitoring the solvent flow in the solvent
channel. Flow control is calibrated for water, acetonitrile, and methanol.
The flow control module’s mass flow sensor measures the flow from the pump.
The auxiliary solvent manager monitors the output and adjusts the solvent
flow accordingly for precise flow from 0.20 to 5.00
µ
L/min.
Sample manager
The sample manager injects the samples it draws from microtiter plates, or
vials, into the chromatographic flow stream. In maximum throughput mode,
the sample manager can perform an injection in approximately 45 seconds,
including a single default wash, or it can do so in less than 60 seconds,
including a dual default wash.
The sample manager accepts standard footprint plates, 5.03
±
0.02 inch ×
3.365
±
0.02 inch, that conform to SBS/ANSI-compliant plates (maximum
height of 2.2 inches, including covers).The sample manager can maintain
samples at any temperature between 4 and 40 °C (39 and 104 °F) in ambient
conditions of 25 °C (77 °F) or less.
