The Agilent 1260 Infinity Binary Pump is designed for applications with RRHT 1.8 µm particle size column technology using columns with an inner diameter of 2.1mm. In addition it 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 configured user-defined. The Agilent 1260 Infinity Binary Pump is the pump of choice for reproducible gradients and high performance, for high-throughput and fast separations including the use of STM column technology. It is ideal for applications where high speed and resolution with uncompromised data quality are mandatory.
