Agilent 1200 Series Capillary Pump |
| Hydraulic system |
Two dual pistons in series, with proprietary servo-controlled variable stroke drive, floating pistons and active inlet valve, solvent selection valve and electronic flow control (EFC) for flow rates up to 100 µL/min |
| Settable column flow range |
0.01 – 20 µL/min, 0.01 – 100 µL/min (with extended flow range kit), 0.001 – 2.5 ml/min (electronic flow control bypassed) |
| Recommended column flow range |
1–20 µL/min, 10–100 µL/min (with extended flow range kit) |
| Column flow precision |
< 0.7 % RSD or 0.03 SD, whatever is greater (typically < 0.4 % RSD or 0.02 SD), at 10 µL/min and 50 µL/min column flow (based on RT, default settings) |
| Composition precision |
< 0.2 % SD at 10 µL/min, 50 µL/min (with extended flow range kit) and 1 ml/min (default settings) |
| Pressure range |
up to 400 bar system pressure |
| Delay volume |
Typically 3 µL from EFC to pump outlet for flow rates up to 20 µL/min; 12 µL from EFC to pump outlet for flow rates up to 100 µL/min; 180–480 µL (system pressure dependant) without mixer for flow rates up to 2.5 ml/min; mixer delay volume 420 µL |
| pH range |
1.0 to 8.5 recommended | |
