G1312A Binary Pump by Agilent: Performance and Precision for Chromatography
The G1312A Binary Pump by Agilent is a key component of modern HPLC systems, designed to deliver optimal performance in solvent distribution. Equipped with a dual-series piston hydraulic system, it ensures a stable and precise flow, a crucial element for reproducible liquid chromatography analyses.
Its adjustable flow rate between 0.1 and 5.0 ml/min allows flexible adaptation to analytical needs, with microliter-level adjustments for perfect control of experimental conditions. The flow precision is maintained at less than 0.07% RSD, ensuring highly reproducible results. Its user-selectable compressibility compensation system optimizes performance based on the solvent’s properties.
Gradient formation is performed at high pressure with an adjustable delay volume between 180 and 900 µl depending on the configuration, allowing smooth transitions between mobile phases. The precision and accuracy of the composition are ±0.5% and ±0.15% RSD, respectively, ensuring sample homogeneity. The pump supports a pH range from 1.0 to 12.5, compatible with many solvents, provided they do not contain agents that corrode stainless steel.
The control and data acquisition interface is managed by Agilent ChemStation, offering connectivity via CAN, GPIB, RS-232C, and an optional LAN. Pressure monitoring is facilitated by a 2 mV/bar analog output, optimizing real-time system performance control.
Maintenance and safety features are carefully integrated, with a leak detection and management system, predictive tracking of seal wear, and electronic traceability of maintenance interventions. The recyclable housing materials reflect Agilent’s commitment to sustainability.
Physically, the pump has a compact format (180 × 345 × 435 mm) and a weight of 15.5 kg, making it easy to integrate into a laboratory environment. Its operation is guaranteed between 4 and 55°C, with tolerance for extreme conditions during storage. Certified according to IEC, CSA, and UL standards, it offers a high level of operator safety.
