1260 Infinity Binary Pump

The Agilent 1260 Infinity Binary Pump is designed to give outstanding performance in both rapid resolution LC and HPLC. The system has been developed for applications with RRHT 1.8 µm particle size column technology using columns with an inner diameter of 2.1mm and is also ideally suited for standard HPLC using 4.6 and 3 mm id columns. Gradient formation is based on a high pressure mixing principle and delay volumes (standard or low) can be easily configured by the operator. The Agilent 1260 Infinity Binary Pump is the pump of choice for reproducible gradients and high performance providing high-throughput and fast separations including the use of STM column technology. For applications where high speed and resolution with uncompromised data quality are required, this is the pump of choice.

  • Configurable delay volume down to 120 µL together with a flow range up to 5 mL/min provides universal applicability.

  • RRLC performance at a HPLC price.

  • Fast and easy change from standard to low delay volume configuration is enabled.

  • High gradient performance even at low % B and narrow-bore flow rates.

  • Electronic damping control creates low baseline noise.

  • The pump is the perfect choice for fast and precise gradients using LC/MS, as well as UV-only systems.

  • Fully exploits the speed and separation potential of ZORBAX Rapid Resolution HT.
