Waters Strengthens ACQUITY Ultra Performance LC System Product Line with Advanced Detectors

Company Broadens Applications for Ground-Breaking Technology

MILFORD, Mass., Nov. 3 /PRNewswire/ -- Waters Corporation (NYSE: WAT) announced today the availability of three advanced detectors specifically designed for Waters ACQUITY Ultra Performance LC(TM) (UPLC(TM)) System. The three detectors are photodiode array (PDA), evaporative light scattering (ELS) and tunable ultraviolet (TUV) models and bring new versatility to the ACQUITY UPLC System for high-resolution analysis of a wide variety of compounds.

The Waters(R) ACQUITY UPLC(TM) is an award-winning, ground-breaking liquid chromatography system that brings laboratories new levels of resolution, sensitivity, speed, and productivity. Whether these scientists are working on new drugs, looking for markers of disease, detecting low level contamination of food or drinking water supplies, recent advances in detector technology mean that scientists using the company's ACQUITY UPLC System platform can obtain more information per unit of time in the laboratory.

Optimized for Ultra Performance LC, these detectors are designed for low dispersion characteristics, high data acquisition rates, and robust performance. Programming and monitoring is easily controlled from within Waters Empower(TM) chromatography software or MassLynx(TM) mass spectrometry software.

New ACQUITY UPLC Photodiode Array Detector

The Waters ACQUITY UPLC PDA detector enhancements include data rates of up to 80 Hz, noise specifications of 10 micro-absorbance units, and an extended linear range allowing scientists to detect and quantify lower concentrations of sample analytes and compare spectra across wavelengths and broad concentration ranges.

With the addition of this detector to the growing suite of ACQUITY UPLC system innovations, scientists now have a full range of options to fulfill multiple detection strategy requirements, allowing more information per run and superb data quality.

Enhanced ACQUITY UPLC Tunable UV (TUV) Detector

The newly enhanced Waters ACQUITY TUV detector is a tunable, dual wavelength ultraviolet/visible (UV/Vis) detector featuring newly designed, patented light-guiding flow cells, low noise performance (6 micro-absorbance units), and support for data rates up to 80 Hz resulting in optimal linearity, resolution and sensitivity for Ultra Performance LC separations.

Innovative ACQUITY UPLC Evaporative Light Scattering (ELS) Detector

For detecting compounds that exhibit little to no UV/Vis response and do not ionize well for mass spectrometry, the Waters ACQUITY UPLC ELS detector is the perfect complement to Ultra Performance LC for analyzing sugars, antibiotics, antivirals, biomolecules, and natural products.

About Waters Ultra Performance LC Technology

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 anything 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 within the last year.

This innovative technology is now in the hands of hundreds of scientists throughout the world. Those who spoke at Waters recent mass spectrometry users conference referred to Ultra Performance LC technology as providing, "a tremendous amount of resolving power," giving "radically shorter chromatographic run times" and "the option of choice for the development of fast LC methods in pharmaceutical development in the near future."
