Specification | |
Eluent Selection | Four different eluent components; each eluent can be proportioned from 0% to 100% |
Pump | Dual-piston (in series), variable speed, 100 µL per revolution |
Settable Flow Range | 0.0 mL/min, or from 0.05 to 5.0 mL/min in increments of 0.01 mL/min. Note: The GS50 is optimized for operation at 1.5 mL/min or less |
Proportioning Type | Low pressure |
Compositional Range | 0% to 100% in 0.1% increments |
Gradient Linearity | Four concave, four convex, one linear |
Flow Accuracy | <1% of set value or ± 2 µL/min, whichever is greater |
Flow Precision | <0.2% |
Compositional Accuracy | <± 1% |
Operating Pressure | 35 MPa (5000 psi), maximum |
High Pressure Limit |
691 kPa to 35 MPa (100 to 5000 psi) in increments of 0.1 MPa (14 psi); trips instantaneously |
Low Pressure Limit | 0 to 34 MPa (0 to 4900 psi) in increments of 0.1 MPa (14 psi); a start-up delay prevents false tripping |
Delay Volume |
Low delay volume: <400 µL Standard delay volume: <800 µL |
Pressure Ripple | <1% at 13.8 MPa (2000 psi) and 1.0 mL/min |
