New Control Software from Waters Released

Milford, Mass., January 11, 2007 – Waters Corporation (NYSE:WAT) announced today that it has released control software that now makes its ACQUITY UltraPerformance LC® (UPLC) System compatible with Applied Biosystems/MDS SCIEX mass spectrometry products controlled by Analyst® software. In conjunction with Applied Biosystems/MDS SCIEX’s release of the latest update to Analyst® V1.4.2 LC/MS control software, Waters will now supply and support additional software which provides full support for the ACQUITY UPLC Systems, including Waters nanoACQUITY UPLC System, on Applied Biosystems/MDS SCIEX’s mass spectrometry platforms.

In August of last year, Waters and Applied Biosystems/MDS SCIEX entered into an agreement for Waters to develop control software for the ACQUITY UPLC System, with support from Applied Biosystems/MDS SCIEX. The new software from Waters is designed to allow scientists to combine Waters® UPLC and Applied Biosystems/MDS SCIEX MS technologies and operate them on a single data system. This new level of compatibility is expected to improve laboratory efficiency by giving scientists what they have been asking for: greatly enhanced ease-of-use of the combined technologies.

UPLC technology has proven to produce narrower and sharper peaks versus HPLC, higher signal-to-noise ratios, and shorter run times – all of which contribute to enhanced mass spectrometer performance bringing laboratories new levels of efficiency. By combining liquid chromatography with mass spectrometry, scientists are capable of obtaining much more information from a single analysis than by either technique alone.

Waters retains responsibility for distribution and support of the ACQUITY UPLC System control software. Applied Biosystems/MDS SCIEX retains responsibility for distribution and support of Analyst® LC/MS control software.

About Waters ACQUITY UPLC System

Waters ACQUITY UPLC® system, first introduced at the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (Pittcon) in 2004, is changing the name of the game in separation science. This system is a first of its kind LC system designed to take full advantage of the potential of novel sub two-micron particles to give scientists chromatographic run times that are up to 9X shorter than today’s fastest HPLC systems, up to 2X better peak capacity or resolution, 3X better routine sensitivity, and, generally speaking, more information from a single run than today’s HPLC systems can provide. The ACQUITY UPLC system received a Pittcon Editors Gold Award at Pittcon 2004 and an R&D 100 Award in 2005 from R&D Magazine as one of the most technologically-significant new products introduced in 2004.
