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.

New spectrophotometer to revolutionise water analysis

HACH LANGE has announced the launch of a major new spectrophotometer, the DR 3900, that Marketing Manager Sarah Blayds says "is light years ahead of anything else in the market."

The DR 3900 employs the latest RFID (Radio Frequency Identification) technology to ensure that an accurate, reliable, traceable record is created for every sample. However, as Sarah Blayds explains: "Improved traceability is not the only benefit of the technology; users are now able to define their own 'set points' for specific sampling locations, so that any results falling outside of these points will be flagged immediately. This facility will be of great benefit to staff such as application scientists who may wish to be alerted to specific conditions such as deviation from normal C:N:P ratios."

How it works
In order to establish a fully traceable system, users will undertake the following procedure:

1.Place RFID tags in monitoring locations
2.Provide sampling staff with personal RFID keyring fobs
3.Utilise a portable, pocket-sized RFID Locator to assign location and sampler ID data to the sample bottle RFID label
4.Utilise cuvettes with new 2D Barcode

The DR3900 will then read sample RFIDs and assign traceability data to the analytical result - date, time, sampler, location and test method.
The DR3900 will also read the sample barcode to determine the batch number and expiry date, and this data will also be assigned to the analytical result.

Eliminating potential errors
Small changes are sometimes made to analytical methods and these represent an opportunity for test errors to occur. However, the introduction of the advanced Barcode 2 and RFID can prevent such errors because the DR3900 will issue a warning if a test requires an update. By simply holding the cuvette box RFID label in front of the DR3900, the user is then able to update the test methodology in the spectrophotometer. The new barcodes also contribute to accuracy by alerting the user if reagents have expired.

Automatic calibration of online instruments
A further benefit of the DR3900 is made possible when the device is networked via Ethernet to facilitate the automatic calibration of HACH LANGE online process monitoring instruments. First, a 'job' is entered on the SC controller of the process instruments and a manual sample is taken. The job (process measurement value, time etc) is sent to the DR 3900 in the laboratory and the sample is analysed using a cuvette test. The result is then compared with the process analyser and the calibration of the process probe is adjusted accordingly (when necessary).

Summarising the advantages of the new spectrophotometer, Sarah Blayds says "When we introduced pre-filled cuvettes, we dramatically reduced the potential for error in the preparation of reagents. The addition of barcodes then helped to reduce error further by making it almost impossible to conduct a test with an incorrect program. However, the addition of RFID technology has effectively closed the loop on traceability and the elimination of error; HACH LANGE customers will now have complete visibility of every aspect of the analytical process."
