Tosoh has developed a new product — Toyopearl Toyoscreen that allows fast identification of the optimal resin for your sample. You can develop the optimal conditions for the separation in addition to the determination of the dynamic binding capacity. All the resins prepacked in these columns are real process resins concerning particle size. Results on the small columns can be scaled up to production.

Rapid structural elucidation of compounds in complex mixtures is a powerful technique in metabolite, degradation and process control applications. The ability to follow the fragmentation pathway through sequential MSn transitions provides added confirmation and increases the selectivity for monitoring compounds of interest in a complex mixture. Previously, the limiting factors in applying this technique were sensitivity at MS4 and higher transitions, and the cycle time required to acquire multiple MSn spectra across a narrow LC peak. Recent developments in trapping, detection efficiencies and scan rates have reduced these limitations and enabled rapid characterization of multiple compounds from single chromatographic runs.

This article introduces the application of high-resolution ultrasonic spectroscopy (HR-US) for the analysis of emulsions and suspensions. The authors outline the principles of the technique and illustrate its application for analysis of the crystallization of lysozyme and the formation of a microemulsion.
