Accurate titration is required for all industries. Manual titration – although common – has its limitations. From wine to mining, titration in some shape or form is performed in practically every industry. When we first learn about titration, it is usually in the form of a tall glass burette, and...Read More
Simplified LPG analysis by ASTM D7994-17. Halides and sulphur in LPG are important factors for corrosion and pollution. Unfortunately, due to the volatile nature of LPG, analysis of these components is more complex than for standard liquid fuels. Automating one analysis for multiple parameters allows laboratories to lower the volume...Read More
Solids used in road construction can be analysed with a hand-held Raman spectrometer. The materials examined are conventional pigments and resins, e.g., CaCO3, TiO2 and DEGALAN®. The measured spectra differ considerably from one another. In order to assess the main differences between the chemical structures, the peaks of the spectra...Read More
Temperature control is a major concern in fine grinding applications and that’s where the Emax comes in. Automatic water cooling removes heat from the grinding jar, reducing the wait between grinding times and the peak in temperature which occurs during standard ball milling. New technologies pose new challenges to science...Read More
Win an ultra modern Metrohm 913 Portable two-channel pH measuring instrument for measuring pH/mV and temperature. You will be optimally equipped for measurements in the field and in the laboratory. 75 years ago, on April 1, 1943, Metrohm commenced operations with a handful of employees in the Swiss town of...Read More
In the modern wine laboratory speed of analysis and management of labour cost are critical for a successful operation. The demands on a modern wine laboratory have increased substantially. Accurate results need to be available fast. Automation has become key. Doing it with the right instruments: BioSystems’ range of photometric...Read More
Storage life, or shelf life, of a product is an important consideration. The longer you store food, the higher the chance of it going bad. How do you know the length of time a product can be stored, on the shelf or in a shipping container? Through accelerated aging, exposure...Read More
The Metrohm Application Note AN-NIR-025 describes the determination of various indices (mainly with ASTM and ISO conformance) for the characterisation of kerosene as aviation turbine fuel using Metrohm near-infrared spectroscopy. The following parameters were determined with the aid of an NIRS XDS Process Analyzer: degree of density in accordance with...Read More
Improve efficiency and reproducibility in the lab with automated titration. Titration is the simplest of techniques. Anyone can do it. Yet it is common to see terrible repeatability for QC samples and reproducibility between analysts. One of the primary reasons is the time taken to perform a manual titration correctly....Read More
The RS 300 XL disk mill has been designed for high throughput with less downtime. The grinding sets are made in Germany to the highest standard, increasing wear resistance and stability. The mill can also hold 80 kgs at a time thanks to the stabilized plane drive, without the need...Read More
One system, all of the parameters Ion chromatography is the chosen technique for oxy-halide analysis and, with persulfate digestion, quantification of total nitrogen and phosphorus is now simpler with ion chromatography too. While both of these applications are ideal for environmental laboratories, they have required two columns running different eluents....Read More
When 5 rings are better than 3. Wider measuring ranges and higher precision in conductivity. Conductivity is a staple of the environmental laboratory. Drinking water, waste water and soils all require it. But not all conductivity probes are created equal. To provide the most convenient conductivity probes, Metrohm have developed...Read More
