Xylem Analytics UK was established in 2003 and has grown to become a leading provider of premium field, online and laboratory analytical instrumentation serving the water & wastewater, ocean & coastal, food & beverage, oil & gas, environmental, chemical and pharmaceutical industries through a number of internationally recognised brands.
Xylem Analytics has developed a reagent-free method of measuring COD, which it has applied to both its’ online and lab offerings.
COD measurements have previously take a long time due to the heated reaction step and have required the handling and disposal of hazardous chemicals. Alongside this, there is a high degree of sample-sample variability with an accuracy of +/-35% accepted as standard.
The move to reagent-free provides rapid results without the associated hazards.
In the online instrument this has been coupled with Xylem's ground breaking ultrasonic cleaning technology, eliminating the need for wipers and allowing the sensors to operate effectively in the most difficult of municipal wastewater environments.
