Making “Green” Chemistry Possible in the Scientific Laboratory

Milford, MA, September 24, 2007 – While many labs focus on the opportunity to reduce hazardous waste disposal costs and look at “greener” and efficient alternatives to chemical analysis, Waters Corporation and Thar Instruments, Inc., Pittsburgh, PA have entered into a new phase of their cooperative agreement first announced in 2005.

The exclusive OEM agreement between the two companies now gives Thar Instruments access to Waters® demonstration facilities and corporate R&D resources to meet the growing market demand for new supercritical fluid /mass spectrometry ( SFC/MS) products.

“This closer strategic partnership gives us the resources that we need to develop our new SFC/MS preparative systems for mass-triggered purifications,” said Dr. Lalit Chordia, CEO of Thar Instruments. “By providing Thar with compatible detectors, software, and expertise, Waters renewed commitment to SFC is evidence that market acceptance for SFC has reached a new level.”

Currently Waters combines its model 3100 single quadrupole mass spectrometer and photodiode array detector with Thar’s SFC systems to meet the demands of pharmaceutical research and development customers.

“As a complementary technique to liquid chromatography, SFC comes with many advantages for scientists who are intent on streamlining many of their analytical and purification processes, who want to take advantage of the power of mass spectrometry and who want to cut their waste disposal costs. For them, the clear choice is to consult the companies with the most to offer in each area – Thar and Waters”, said Rohit Khanna, Ph.D., V.P. of Worldwide Marketing, Waters Division of Waters Corporation.
