Background

Infrasoft International (ISI) was formed as a partnership between Dr. John S. Shenk, Professor emeritus of Pennsylvania State University, and Mark Westerhaus in 1983 .  Dr. Shenk brought an a background in agronomy, and Mark Westerhaus an expertise in statistical analysis and computer programming.  These interests complemented each other perfectly, and the two found the perfect technological outlet for their work:  NIR Spectroscopy. 

Through the years, this partnership has brought many unique and innovative ideas to the NIRS field, including outlier detection, instrument standardization, LOCAL calibrations and other advanced chemometric techniques. ISI has been granted patents that have pioneered the application of NIR spectoscopy to the analysis of natural products.

Early FORTRAN programs have been replaced with up-to-date 32 bit programs, and the group has grown to 7 employees, but the innovation and performance continue to be a hallmark of ISI's products. 

ISI is located in State College , Pennsylvania with Mark Westerhaus as president.  Dr. Shenk retired from the business in 2005.

ISI is a joint venture with FOSS A/S based in Hillerod , Denmark , a leading analytical instrument manufacturer.  FOSS is the exclusive supplier of ISI products.
