When new laboratories are planned it is important from a budgetary point of view that the facility accommodates as wide a range of applications as possible
Distillation equipment based on the Kjeldahl method are advantageous in this respect as their key component is a steam distillation system.
This type of sample preparation is called for in many different analysis procedures.
Over recent years Buchi Labortechnik has fully redesigned its Kjeldahl systems, with the result that they are now capable of much more than traditional protein determination.
A new application note describes the use of the K-355 distillation unit for the determination of phenols in the concentration range 200-5000ug/l by means of a photometric determination using 4-aminoantipyridin in compliance with relevant applicable standards such as ISO 6439:1990, EPA 9065, DIN 38409 H16-3.
Further interesting applications in the fields of waste water and sewage sludge include the determination of volatile acids, COD (chemical oxygen demand) or ammonium content.
These and other applications in the context of environmental analyses are available free on request from Buchi Labortechnik in Switzerland.
