Item Specification
General High pressure mixing, binary gradient.
Priming Ability to self-prime from a solvent container on
the floor with wet pump heads and dry tubes
(no intervention from the operator such as a
syringe).
Number of solvents Up to four (4): A1, A2, B1, and B2. User must
choose A1 or A2 and B1 or B2 before the start of
the gradient.
Solvent and seal-wash
containers
User-selectable.
Primary wetted materials 316 stainless steel, UHMWPE, Sapphire, Ruby,
Tefzel (ETFE), Teflon (FEP, PTFE, PFA),
Nitronic 60, Valcon H, Chemraz, and PEEK™.
Pump seal-wash (for two
seal-wash pumps)
Pump and seals required to wash the rear of the
high-pressure seal (pulsed type flow, about
20 µL per pulse).
Flow rate, pressure
operating envelope
See page B-9.
Flow rate increment 0.01 mL/min.
Delay volume Delay volume of the binary gradient module is
effectively zero because the two pumps are
connected together at the outlet filter/tee.
System delay volume depends on the tubes
and/or mixers and fittings between the outlet of
the binary gradient module and the column
inlet.
Flow accuracy ±1.0% of required flow or 10 mL/min, whichever
is greater. Flow rate 1.00 to 150.00 mL/min,
using water or MeOH, back pressure
approximately 4140 kPa (41 bar, 600 psi).
