The BI-MwA Multi-Angle Light Scattering (MALS) detector from TESTA Analytical claims to offer the highest performance to price ratio of any light scattering system available for molecular weight determination.
It is designed to increase the capability of any GPC/SEC system, enabling the precise and accurate determination of the molecular weights of polymers and nanomaterials in solution. Compact in design, the vertical flow path of the BI-MwA avoids trapped bubbles. The flow cell inside the BI-MwA has no sharp corners, only conical shapes, meaning previously analysed samples are easily flushed out to eliminate risk of contamination.
The instrument allows users to eliminate time-consuming column calibration and improve data quality. It is designed for easy use whilst incorporating sophisticated features. Once injected into the low-volume, 7-angle flow cell, the sample is illuminated by a temperature-stabilised, precision power-controlled diode laser. The stable, high-sensitivity, low-noise CCD detector automatically collects the scattered light. Software then extrapolates the data to zero angle to enable precise absolute molecular weight determination.
