Table A-1 Operational Specifications
Item Specification
Number of eluents One to four.
Modes of operation Gradient, isocratic, and flow programming
Operating flow range 0.00 to 45 mL/min (225 µL heads), in 0.01-mL increments.
0.00 to 20 mL/min (100 µL heads), in 0.01-mL increments.
Composition range 0 to 100% programmable in 1% increments for each of four
reservoirs: A, B, C and D. Total composition must sum to
100%.
Compositional accuracy Better than 1.0%, independent of pressure.
Automatic eluent sparging Standard, helium gas, input gas pressure range 50 to 150 psi
(3.5 to 10.5 kg/cm
2
).
Helium flow rate range 0 to 100 mL/min, programmable in
1 mL/min increments.
Pressure maxima 6000 psi (420 kg/cm
2
) at 10 mL/min.
1000 psi (70 kg/cm
2
) at 45 mL/min.
Programmable pressure limits Lower: 0 to 5950 psi (0 to 416.5 kg/cm
2
)
Upper: 51 to 6000 psi (3.6 to 420 kg/cm
2
)
