Advanced Materials

A leading solvent manufacturer uses the Masscal DRG to monitor the quality of high-purity materials quickly and without environmental impact using just a few drops.

NIST is using the Masscal HT system to characterize advanced materials including carbon-nanotube composites. This work requires the unique sensitivity of Masscal HT to make QCM nanoscale measurements at elevated temperatures.

A consortium of automobile manufacturers used the Masscal G1 to track the curing of thin films for specialty applications.

The curing and physical stability of so-called "Smart Coatings" have been measured using the Masscal G2 with the extra precision of internal humidity generation and control. These "smart coatings" have advanced properties including changing physical properties and self-healing based on the distribution of nanoparticles within the thin film.

Food, Personal Care
and Bio Applications

Work completed at Harvard University demonstrated the capability to model the sorption of personal products using the Masscal G1.

Drexel University has a continuing program to study packaging materials and related products using a Masscal G2 upgrade to their original Masscal G1 purchase. Drexel has also measured sorption isotherms and ligand binding energies in biological solutions.

Patent-Pending "Droplet Residue Gravimeter" for NVR Released

Masscal introduced the new "Masscal NVR" system and placed the first commercial unit in an industrial laboratory for quality control of ultra-pure materials. The system addresses the need to perform non-volatile residue analysis faster, cheaper and with less waste than traditional NVR methods. It also provides unparalleled sensitivity of less than 1 nanogram. This technology was developed in cooperation with the University of South Florida under sponsorship of the National Science Foundation.

Masscal Supports Haiti and Chile Relief

Masscal immediately responded to the need to provide assistance to the people of Haiti after the devastating earthquake of January 12. In addition to cash donations, the staff of Masscal has volunteered many hours to the relief effort, primarily through the American Red Cross, www.redcross.org. This effort has now been expanded to include the victims of the Chile earthquake as well. We urge all of you to join with us. Charity Smith, President of Masscal, stated succinctly "It's the right thing to do."
