About

Whether you want to check the carbon content of waste water or keep an eye on the salt content of your process water, when it comes to water analysis, HACH LANGE is the perfect choice. We have years of experience in water analysis and offer a broad range of services.Our company history dates back to Berlin 1933, when Dr. Bruno Lange set up a company in his own name employing six people. Inventions such as the photometer and later on cuvette tests have revolutionised the field of analysis, making it possible to conduct extensive analyses without the need for in-depth knowledge of chemistry.HACH LANGE was born in 2004 when Dr. Bruno Lange joined forces with HACH, an American company specialising in electro and photochemistry. The expertise of these two companies is now combined, benefitting you, our customers!That's not all, our company is continuing to grow and already has 22 subsidiaries around the world, including branches across Europe, China and the USA.

Free Laboratory Training Days

A good understanding of the basic principles behind all measurement techniques is essential if laboratory staff are to attain high levels of accuracy and reliability.

For this reason, HACH LANGE, one of the world's leading manufacturers of laboratory testing equipment, has established a series of free training courses.

Initial courses, held at the company's headquarters in Manchester, have focused on pH, conductivity and turbidity, and participant feedback has demonstrated a very high level of satisfaction. Garry Grigg, Analytical Chemist for Chemtura found the course very helpful, commenting, " I was particularly pleased with the content of the course. It was obviously designed to reinforce basic principles whilst providing practical information and tips on how to maximise the performance of our instruments."

The laboratory at Chemtura supports the production and quality control of flame retardant plasticisers and water treatment chemicals.

Dr Geoff King provides training on pH, outlining key principles including the role of the indicator and reference electrodes, the factors affecting choice of electrode, and the affects of chemical composition and electrolytic strength on measurement technique. The preparation or purchase of calibration or buffer solutions is also discussed.

Training includes sessions on conductivity measurement in the laboratory. The relationship between solution resistance and conductance is explained in addition to a description of the factors affecting choice of electrode. Good measurement technique is explained in conjunction with key issues such as the 'cell constant' and polarisation avoidance. Calibration techniques and temperature compensation are also covered for all types of water including ultrapure.

Christian Pust provides training on turbidity measurement covering important subjects such as principles of measurement and the differences between USEPA and ISO Standards. Information is also provided on calibration, the ratio mode and the effects of stray light.

Details on future training courses can be obtained directly from sarah.blayds@hach-lange.co.uk or by subscribing to the company's regular email 'H2O Newsletter' via the web site www.hach-lange.co.uk.
