Precious samples for particle size analysis need no longer be wasted with the launch of a new small-volume cell by Brookhaven Instruments. This cell requires only 180 microliters (μL) or less of sample material – usually 2-3 mL of suspension are needed to make measurements. The small-volume cell is particularly relevant for pharmaceutical research involving peptides, proteins, and DNA, where often only very small amounts of sample are available.
Low cost disposable cells are usually used as they eliminate the risk of cross-contamination between samples. Acryclic square cells are available for aqueous and simple alcohol suspensions, and round glass cells with re-usable Teflon stoppers for aggressive solvent suspensions. Other options include square glass and quartz cells.
For decades, Brookhaven Instruments has pioneered the design and manufacture of particle characterization instrumentation. Based on the principles of dynamic light scattering (DLS), the NanoBrook is designed for fast, routine, submicron measurements. Applications of the NanoBrook include polymer latexes, oil/water emulsions, paints and pigments, inks and tones, and cosmetic formulations.
