The COMET (Cell Operation and Maintenance Enhancing Technology) is an ultrasonic transducer that agitates the flow cell and loosens particles adhering to the cell walls or windows. This device may be integrated with the flow cell manifold of a DAWN, miniDAWN or microDAWN detector. This accessory, included with all MALS detectors beginning in 2018, is available for installation in previously shipped instruments. The COMET is directly controlled by Wyatt’s software packages for MALS, ASTRA and CALYPSO and can be programmed to automatically clean your flow cell after or even between measurements.
Moreover, the device operates in situ while the mobile phase is flowing through the cell. There is no need to disconnect any fluid fittings, change solvents or disassemble any of your setup the solvent flushes out the particles.
Cleans MALS flow cells automatically by agitating the fluid and loosening particles from the glass surfaces; integrates inside the chassis of the MALS detector and is either controlled manually from the instrument’s front panel or automatically via an ASTRA method.
