As particle sizing methodologies become more sophisticated, it is becoming increasingly difficult to measure the degree of resolution offered by state-of-the-art instruments. Image analysis methods, for example, offer one of the highest resolutions available, but until now, it has been difficult to quantify the resolution. To address this challenge, this firm is launching a new Multimodal Standard (photo). In this standard, eight distinct peaks have been produced between 500 and 2,000 microns. For very small particle sizes, a Multimodal Standard with ten peaks between 0.1 and 1.5 microns has also been prepared for evaluation. – Whitehouse Scientific, Waverton, U.K.
