Shimadzu LC-20AP Preparative LC Pump

Shimadzu Scientific Instruments has introduced the next-generation LC-20AP Preparative LC Pump, which can be used for analytical, semi-prep and prep LC applications without changing pump heads.

The wide flow rate range (0.01 to 150 mL/min) with high pressure tolerance (6000 psi up to 100 mL/min and 4350 psi up to 150 mL/min) makes it possible to use 50 mmID x 250 mmL 5 µm-particle size columns to achieve high-resolution and high-efficiency purification and improve productivity by five to 10 times over the previous models.

The flow rate accuracy and precision were improved by minimising dead volume in the pump heads and using higher resolution micro-stepping motor control so that the pump can be used at an analytical flow rate range, such as 1 mL/min, with high reliability.

Overall productivity and quality of the purification has also been improved. If configured as an analytical/prep system, a user can develop a method at analytical scale then immediately convert the method for prep scale.

Shimadzu provides a tool to easily convert methods between analytical and prep for support customers. In addition, the LC-20AP pump can be used with Open Solution automated prep LC/MS software, which allows researchers to purify their compounds by simplifying the workflow in a walk-up environment.

Shimadzu has also responded to environmental concerns. LC-20AP consumes 40% less energy in comparison with the previous model due to a newly designed, high-efficiency power supply and motor control electronics.
