Brochure describes colloid stability
analyser
Ultrasonic Scientific, innovator in high-resolution ultrasonic spectroscopy (HR-US) for material analysis, has produced a new brochure detailing its HR-US colloid stability analyser
The brochure provides a comprehensive overview of the technical characteristics and analytical capabilities of the new colloid stability analyser, highlighting the instrument's value for R+D and process development scientists and QA/QC analysts in the pharmaceutical, food and beverage, cosmetics, personal care and other industries The new colloid stability analyser is said to be the first of its kind for sedimentation and stability measurements

Analytica preview: Ultrasonic Scientific
A new high-resolution spectrometer takes centre stage, aiming to move ultrasonic technology from hospitals and submarines into the pharmaceutical laboratory
It can analyse emulsions and suspensions while also having the ability to perform non-destructive and small sample analysis.
In addition, the HR-US instrument enables the analysis of opaque materials.
This unique analyser can be pressurised up to 10bars, allowing analysis of liquids with low boiling points and liquids at high temperatures (above boiling point).
The all-inclusive brochure is also enhanced with general information on HR-US and its applications.
In addition, the new brochure illustrates an application - aggregation/sedimentation of solid polymeric particles - to further demonstrate the reliability and practicality of Ultrasonic Scientific's colloid stability analyser.
Experimental results show that unlike traditional techniques, the colloid stability analyser provides precise quantitative measurements, allowing accurate information to be gathered on average particle size, particle concentration and rate of sedimentation/creaming and assessing degree of flocculation/aggregation in suspensions.
Ultrasonic spectroscopy is a non-destructive technique that is based on precision measurements of parameters of high-frequency sound waves propagating through analysed samples.
These waves propagate through most materials including opaque samples (down to a volume of 0.03ml) and allow direct probing of intermolecular forces.
