"Green Chemstry" in the Laboratory
Using mills as efficient and ecologically friendly synthesis reactors
The term "green chemistry" is commonly used to describe chemical procedures which meet specific requirements with regards to the conservation of resources and protection of the environment. The objective is to avoid undesired by-products by selecting adequate reaction procedures and media. A typical example is the production of bio fuel which has become an ecologically friendly alternative for many drivers....

Sensible and self-monitoring
Online process for soft water control
For the generation of soft water are mostly used ion exchanging devices with generation of sodium chloride since the beginning of the Sixties. The generated soft water quality and soft water quantity are depending thereby on the static and dynamic characteristics of the softening plant in operation....

Chemometric Spectroscopy
Modular Software for Routine Analysis
Chemometric Spectroscopy is the term used to describe the direct combination of a spectroscopic measurement with a chemometric data evaluation procedure, typically a multivariate statistic method, so providing quick and reliable deduction of the qualitative and quantitative properties of a sample from its spectrum. A multi-linear regression (MLR) or partial least squares (PLS) regression is usually used for the quantitative determination of individual or combined parameters, while substance identification generally relies on techniques such as discriminant or cluster analysis....

Gröger & Obst Analyzers for Simultaneous Measurement of TOC and VOC
Options for the Modification of TOC Standard Equipment
To determine the degree of organic pollution of waste water, labs prefer the kind of analytical test methods that yield useful results without being costly or demand the use of large-scale equipment. To achieve this end, labs employ methods that are sensitive to the oxidizing capability of all organic matter and record the so-called sum parameters (e.g. TC, TOC, DOC, TIC and VOC). These parameters are instrumental in water analysis and likewise in the determination of solutes and the physicochemical variables....
