Automated Water Analysis  

The new AP 3800 multi laboratory robot from HACH LANGE (Germany) takes care of water analysis from start to finish, including sample preparation – also when a digestion step is needed. The basic version is pre-programmed for the LANGE cuvette tests for COD, total phosphorus, total nitrogen, ammonium, nitrate and nitrite. More methods can be added at any time. The AP 3800 multi uses the proven DR 3800 sc spectrophotometer as its detector.

A multifunctional arm and a variety of tools carry out all the necessary work steps of the cuvette tests, such as pipetting, dosing, inverting, shaking, thermostating, and manipulating DosiCaps.

The AP 3800 multi offers a high level of flexibility in single and series mode. More than one parameter can be analysed and evaluated in parallel. The control software shows a graphic overview of the current status of the sample sequence. An intelligent time management system monitors the work steps of the methods meticulously. It interleaves several methods, so that, for example, a straightforward sample analysis can be in progress while sample preparation for a complex analysis is being carried out in the digestion block.

The LANGE cuvette tests are designed to satisfy sustainability criteria at all stages of their life cycle, from manufacture to proper disposal. In recognition of this, HACH LANGE has been nominated for the 2009 German Sustainability Award in the category “Germany’s Most Sustainable Products and Services”.
