Presearch has introduced the Chorus 220 high pressure solvent delivery system.
Presearch has introduced the Chorus 220 high pressure solvent delivery system.
This system achieves precise, pulseless fluid delivery at flow rates as low as 20nl/min required in today's nanoscale and capillary LC.
The Chorus 220 system provides true nano-litre solvent delivery without flow splitting used in conventional low flow LC pumps.
This approach avoids unintentional changes in flow rate due to split ratio fluctuations caused by for example increased column resistance or viscosity changes during gradient formation.
Its unique design delivers accurate gradients that are ideally suited for high sensitivity UV, fluorescence or electrospray mass spectrometry using capillary column.
Despite its high performance the Chorus 220 is compact in size, making it an ideal companion for any LC-MS system.
