LANGE cuvette tests used by the professionals for 40 years
The document reports of the advatages of the LANGE cuvette tests. Author: Dipl.-Ing. Petra Puetz, HACH LANGE Lab product specialist. The launch of the world s first ready-to-use reagent packages for photometric analysis in the 1960s had a substantial effect on environmental analysis. Today LANGE cuvette tests and photometers are indispensable elements of operational analysis. Innovations such as 10-fold rotational measurement have simplified analysis even further and made it more reliable. Quality assurance procedures (analytical quality assurance ADDISTA, round robin tests) are carried out and documented. The correct processing of used reagents in HACH LANGE s own certified environment centre completes the LANGE cuvette test-system. 8 pages

Maximum simplicity and cost savings in analysing surfactants
Author: Dr. Stefano Malusardi, Sales Manager Laboratory, HACH LANGE srl (Italy). The Italian 152/2006 law foresees wastewater outlet limits for the total surfactants. Each wwtp, industrial or municipal, has to analyse surfactants divided into their components: anionic, non-ionic and cationic surfactants. Official standard methods are prescribed for two species (anionic and non-ionic surfactants), but they are very time consuming, complicated and dangerous due to the chlorinated solvents used. Therefore HACH LANGE developed cuvette tests to help customers in managing these kind of analysis and solving their purpose. 4 pages
