The SEC-3010 dn/dc Refractometer is a deflection type instrument designed for batch mode applications. This value is required as a parameter in molecular weight measurements using static light scattering. A second interesting application is the determination of sample concentration, when dn/dc is known.
This feature is especially useful when proteins are investigated, as concentration is very often unknown. In batch mode, the instrument comes with BI-DNDCW software for use with an external PC.
