New Spectroquant® test kits for COD analysis in waste water
Broader measurement range, greater tolerance of chlorideby Merck Millipore
Being recognized as the leader in waste water analysis, Merck Millipore introduces two new COD test kits. With this expansion of the Spectroquant® COD test kit product line, you can now measure much higher levels of COD, even if your sample contains significant chloride. Nine different COD test kits cover the measurement range from 4.0 – 90,000 mg/l. Choose the best one based on your sample range.
Is your waste water relatively clean?
For measuring COD levels in relatively clean water, most of our customers successfully use the existing Spectroquant® test kit measuring COD from 4.0 – 40 mg/l. However, we heard from some customers, e.g. in waste water treatment plants or those analysing ground or surface water, who needed something more. They requested the capability to measure COD in the semi ultra low range. We listened and developed a new kit that meets these unique needs covering the range from 5.0 – 80 mg/l. Broadening the measurement range from 5.0 – 80 mg/l also means the new kit is compliant with the German DIN 38409 H44 regulations – an added benefit at audit time.
Measure COD in highly polluted water samples, high chloride will not interfere.
Merck Millipore also offers a new Spectroquant® test kit developed especially for measuring COD in highly polluted water, such as untreated waste water. Most commonly done as a first screening, analysis of these samples can be tricky. Not only do they contain a very high COD level, they also can contain a huge quantity of chloride. The new kit measures COD in the ultra high range from 5,000 – 90,000 mg/l and also tolerates as much as 50,000 mg/l chloride in your sample. This is absolutely unique in the market since most kits from other suppliers only tolerate 1000-20000 mg/l chloride.
The new Spectroquant® COD test kits join a complete range of products for water and waste water analysis. Merck Millipore has spent years developing comprehensive, certified quality analysis processes. Take advantage of our experience. From instruments to test kits we offer a complete system for ensuring the quality of your water and waste water analysis.
Comprehensive quality documentation
For each Spectroquant® COD Test 2 different quality assurance documents are issued. The lot certificate includes specific data about the lot. The certificate of quality details the results of stringent quality tests and serves as information for auditors at accredited laboratories.
The Spectroquant® photometers are programmed to measure more than 170 different parameters, but choosing the right one is easy. Each COD test cuvette has a barcode label. Inserting the cuvette into the photometer, the instrument reads the barcode and automatically selects the correct method.
Free software updates
Regulations change, new test methods are developed. However, you do not have to worry about it. Merck Millipore provides regular software updates to keep your Spectroquant® photometer up-to-date. Programming your photometer for use with the new COD test kits is easy.
