Used AGILENT G7112B 1260 Series

The Agilent 1260 Infinity II Binary Pump is suited for LC applications using conventional or superficially porous particle columns, as well as STM column technology. Gradient formation is based on a high-pressure mixing principle. Standard or low delay volumes can be easily configured by the user. The Agilent 1260 Infinity II Binary Pump offers reproducible gradients and high-performance, providing high-throughput and fast separations. The pump is suitable for routine applications, with UV or MS detection, where high speed and resolution with uncompromised data quality are required.
