Pumps
The NGC systems can have up to three high-precision pumps: two system (or
gradient) pumps (pump A and pump B) and one sample pump. The system pumps
can create isocratic or linear gradients at a range of precisely controlled flow rates
and pressures. The sample pump can load large sample volumes onto a column or
fill large sample loops. Flow rates on all pumps can be controlled to avoid
overpressure.
