Effective water purification is more than just a simple formula and can be highly dependent on such variables as starting water quality, system design and end-user requirements. A number of water treatment methods are available to improve purity, but generally no one system alone can remove all contaminants highlighting the need to employ several techniques into an integrated system to achieve the required water level quality.

Emission tailored to DNA inactivation

The application of UV energy plays an integral role in the process of converting feed water into quality lab water or Reagent Grade Water (RGW) and forward, including the generation of ultrapure Type I lab water. In existing systems, light at 185 nm helps eliminate trace organics while mercury lamps emitting at 254 nm wavelengths have been used for microbial disinfection for decades. However, this particular wavelength is not the best candidate for optimum germicidal irradiation. Although wavelength susceptibility may vary slightly, the action spectrum for maximum microbe DNA absorption is typically reported to be between 265nm – 267 nm. Klaran UVC LEDs are specifically tuned to emit high germicidal power in the range of 250-280nm, peaking at 265nm, which makes it the optimum choice over traditional mercury technology.

Flexible Lab Solutions

As the demand for ultrapure lab water increases, maintaining large production quantities on hand and in storage for central distribution is not a cost effective option. Instead, a more suitable approach under adoption is the generation of quality feed water distributed to point-of-use polishers to meet the needs of the researcher, their programs and usage within their lab. These innovative benchtop devices take on numerous shapes and sizes, highlighting the importance of delivering reliable, high power UVC energy to ensure quality ultrapure lab water at point-of-use.

Benefits of incorporating Crystal IS UVC LEDs

Klaran UVC LEDs offer distinct advantages over traditional mercury lamps when designing point-of-use polishing equipment or incorporating UVC energy to improve the quality of upstream feed water systems.
