New Products: Waters, Agilent, Thermo Fisher

Premium

Waters this week introduced its Cortecs 2.7 micron HPLC columns with solid-core particle technology.

The columns run at lower pressures while delivering higher efficiencies and give researchers the flexibility to either use longer column lengths to improve resolution or higher flow rates to speed analysis time, the company said.


Agilent this week introduced its 1290 Infinity Multisampler for use with its 1290 Infinity LC system.

The autosampler offers improvements in cycle time, carryover, and cooling, the company said.


Thermo Fisher Scientific this week launched its SOLAμ solid phase extraction micro elution plates.

The plates are designed to deliver robust, reproducible processing at elution volumes as low as 25 μL, the company said.
