Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability and performance. If any repairs are necessary, the instrument is highly user-serviceable and easy to maintain.

The process to reduce the amount of microorganisms in water, by means of ultraviolet light is called “ultraviolet disinfection”. It is used in all kinds of water to reduce the amount of microorganisms such as bacteria, protozoa, viruses, fungi, algae. Ultraviolet (UV) light is a natural part of sunlight, whereas the short wavelengths are absorbed by the protecting ozone layer. UV lamps designed for water disinfection use a gas mixture containing the element mercury (Hg). The Mercury vapour is an advantageous gas for UV disinfection applications because it emits light in the germicidal (‘germs killing’) wavelength range (UVC and UVB).
