The Agilent 1100 Binary Pump (G1312A) is an advanced piece of chromatography equipment designed for precision and reliability. This model combines innovative features that optimize performance while minimizing bench space, making it an essential asset for any laboratory setting.
Features:
- Lowest Volume Capillary Connections
- Features two in-series dual-piston pumps housed in a compact design, ensuring minimal internal and external volume. The internal volume ranges from 180 to 480 µl (without mixer), making it perfect for applications requiring low solvent consumption.
- Low Flow Capability
- Operating starting flows at a minimum of 50 µl/min, this pump allows for reproducible gradient formation at low flow rates while efficiently degassing solvents.
- Reliable Design
- Equipped with electronically controlled active inlet valves, the Agilent 1100 Binary Pump can handle flow rates of up to 5.0 ml/min. Its floating piston design incorporates a path-of-least-resistance principle, ensuring maximum seal lifetime for longevity and minimal maintenance.
Specifications:
- Flow Precision:
- <0.3 % RSD (typically <0.15 % RSD), ensuring high reproducibility for critical applications.
- Flow Range:
- Adjustable setpoints from 0.001 to 5.0 ml/min in increments of 0.001 ml/min, providing flexibility for various methodologies.
- Operating Range:
- Capable of operating across a pressure range of 0 – 40 MPa (0 – 400 bar, 0 – 5880 psi), the pump maintains outstanding performance even under high pressure conditions.
- Pulsation is kept below 2% amplitude (typically <1%) at a 1 ml/min flow of isopropanol, ensuring smooth and steady flow.
- Facilitates user-selectable compressibility compensation based on mobile phase compressibility, enhancing operational efficiency.
- Delay Volume:
- Depending on back pressure, the delay volume ranges from 180 – 480 µl (600 – 900 µl with mixer), ideal for precise method conditions.
- Recommended pH Range:
- 1.0 – 12.5, with a stipulation that solvents with pH < 2.3 must be free of acids that could corrode steel components.
- GLP Features:
- The system includes electronic logging of maintenance and error records. Early Maintenance Feedback (EMF) continuously monitors pump usage and provides feedback if preset operational limits are exceeded, ensuring adherence to Good Laboratory Practice (GLP) standards.
