Make more money and free your time by automating your lab. Learn about automated chemistry.
Automated Wet Chemistry allows you to analyze more samples per day. More samples per day means more money for commercial labs, and more time for everyone. By giving you more time you are free to analyze more samples.
An overview of analyzers to help you make money. The choice you make when buying an automated analyzer should not be based on personal preference, but instead, what is best for you. Much of the manufacturer literature is biased to the particular technique they sell. This is understandable but you, the user of automated analyzers, should be aware of the whole truth and not just some manufacturer's version of it.
This is where the author becomes biased. The bias, however, is based on over 27 years of experience in the analytical laboratory. One of the biggest pains is cyanide distillations. The most significant cause of incorrect results in cyanide analysis is distillation. The OI CNSolution offers you the ability to analyze cyanide accurately without distilling. Not only more accurate, it is faster significantly increasing throughput. With a CNSolution, total cyanide sample capacity is no longer limited to the number of distillation spots.

A true discrete analyzer does not have a flow-cell. A true discrete analyzer dispenses sample and reagent into individual compartments where they are reacted and measured. Instruments with flow-cells are not really discrete analyzers and are more equivalent to an open air reaction continuous flow analyzer. Read here what a real discrete analyzer is supposed to do.
