Thermometric titration – the missing piece of the puzzle
Titration is a well-established analysis technique taught to each and every chemistry student. Titration is carried out in nearly every analytical laboratory either as manual titration, photometric titration, or potentiometric titration. In this blog entry, I would...
Trace metal analysis with solid-state electrodes – Part 4
In this series of articles featuring various solid state electrodes, we have introduced the new Bi drop electrode and the scTRACE Gold electrode and their potential in the determination of heavy metals in drinking water. In Part 4, we introduce the next type of...
Oven method for sample preparation in Karl Fischer titration
Maybe you have experienced one of the following situations in the laboratory. You need to determine the water content of a sample using Karl Fischer titration and you realize one or more of these issues: The sample does not dissolve in the KF reagent. No solubilizer...
Fresh shrimp – made in Switzerland?
Shrimp from Rheinfelden SwissShrimp AG, based in Rheinfelden, Switzerland, is the largest producer of shrimp in Europe. Michael Siragusa, a chemist and Technical Operations Manager, introduced us to the company during a visit and explained why a fully automatic IC...
Frequently asked questions in near-infrared spectroscopy analysis – Part 1
Whether you are new to the technique, a seasoned veteran, or merely just curious about near-infrared spectroscopy (NIRS), Metrohm is here to help you to learn all about how to perform the best analysis possible with your instruments. In this series, we will cover...
Exposing secrets of ancient Greek civilization through chemistry
This week, learn the story of how analytical instrumentation from Metrohm helps underwater archaeology locate hidden treasures beneath the seafloor. Antikythera Mechanism: a machine lost to time One of the most fascinating items ever salvaged from an ancient...
History of Metrohm IC – Part 3
Part 3 of this series on the history of ion chromatography development at Metrohm focuses on the near past, from the mid 2000s until a few years ago. Here, sequential suppression was introduced, making analysis even more sensitive with the removal of baseline...
Trace metal analysis with solid-state electrodes – Part 3
In Part 2 of this series on trace metal analysis with solid-state electrodes, we introduced the scTRACE Gold electrode. The third part of this series explains even more applications which can be performed with this electrode, but this time after modifying the gold...
Forewarned is Forearmed: Error and risk minimization in process analysis – Part 3
In the course of life, each of us learns to trust our gut feelings or our experiences to avoid situations that seem dangerous or risky. You quite literally sense potential dangers with an uneasy feeling. Who hasn't painfully learned that touching a hot stove top isn't...
History of Metrohm IC – Part 2
In the second part of our series behind the development of high quality ion chromatography instrumentation at Metrohm, I will cover the mid 1990s until the mid 2000s. During this time, Metrohm focused on modular IC, lowering background suppression, as well as bringing...
