microDAWN™


The microDAWN™ can be coupled to any UHPLC-SEC system to determine absolute molecular weights and sizes of polymers, peptides, or proteins directly, without resorting to column calibration or reference standards. The  microDAWN™ produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC, while meeting or exceeding the sensitivity of the miniDAWN®.

Distinctly from the miniDAWN, the microDAWN™ is uniquely suitable for use in conjunction with UHPLC Size Exclusion Chromatography (µSEC-MALS) thanks to its small interdetector dispersion. In some cases it may be used with ion-exchange or other types of chromatography. Regardless of the specifics, the microDAWN™ produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC.
