Ultrasonic Scientific, a world leader in the field of High-Resolution Ultrasonic Spectroscopy (HR-US) for material analysis, will be exhibiting its latest HR-US accessories at the 2004 Institute of Food Technologists (IFT) Food Expo, booth 2799, Las Vegas, Nevada, 12th-16th July.

The 2004 IFT Food Expo is where suppliers of food ingredients, laboratory, packaging, and research and development services present their latest products and developments.

Being launched on booth 2799 will be the Ultrasonic Scientific HR-US Pressurising System, which provides pressurisation of analysed samples.

The unit has an internal compressor delivering a desired pressure to each of two cells of HR-US spectrometers.

Cells can be pressurised independently or simultaneously for differential measurements and two individual pressure outlet lines allow the user to set different pressures in each cell if required.

The HR-US Pressurising System is a powerful tool for customers who need to analyse samples at pressures above 1 atmosphere.

This means that the system can be used to analyse bubble suppression, liquids with low boiling points, solubility of gases and gas bubbles in liquids.

Ultrasonic Scientific will also feature the Titration Accessory on booth 2799, which allows enhanced analysis of intermolecular interactions, ligand binding, aggregation processes, gelation and phase transitions amongst others.

The Titration Accessory enables measurement of the associated microstructural and molecular rearrangements in the sample and allows precision change in concentration of selected chemical components in the ultrasonic cell.

With the Titration Accessory, titrations are performed automatically by computer control whilst a powerful stirring option permits a quick and homogenous mixing of titrant and analyte.

In addition, Ultrasonic Scientific will demonstrate its versatile HR-US 102 P high-resolution spectrometer, which offers the flexibility of using the HR-US 102 with a full complement of external cell modules.

The 102 P operates with a standard liquid cell, a cell for semi-solids and a cell for flow measurements.

These modules offer even greater flexibility for material analysis and are ideal for Research and Development and Quality Analysis/Quality Control applications in food, pharmaceutical, personal care and polymer industries.

The complete range of "P" version spectrometers includes: HR-US 102-P- Ultrasonic Spectrometer with liquid cell and external module interface; HR-US 102 SS-P - Ultrasonic Spectrometer with semi solid cell and external module interface; and HR-US 102 FT-P- Ultrasonic Spectrometer with flow through cell and external module interface.

The HR-US 102 P can analyse food products such as milk, fruit juices, beer, etc without the need for dilution or addition of chemical markers.

This is as a result of its ability to analyse optically opaque systems.

The instrument's impressive dynamic range allows for the analysis of liquids, concentrated emulsion, and hard gels, and has been extensively used in the monitoring of gelling processes (yogurts, thermal induced starch etc) and crystallisation in oils/fats.

Other applications where the HR-US 102 has being incorporated into the food industry is the monitoring of ensyme activity in foods, coagulation in milk based drinks, composition analysis, sedimentation processes and surfactant/micelle analysis.

The HR-US technique's broad range of applications and non-destructive/non-invasive nature makes it an ideal tool for use in the food research and food processing sectors.
