As moisture analysis is heavily relied upon in industry, it is imperative the basics of moisture analysis are taught. Karl Fischer titration provides the most accurate analysis for moisture. At high levels of moisture, g/L to %, Volumetric Karl Fischer titration is a fast and cost effective technique. At low...Read More
Portable Raman instrumentation in the classroom provides an excellent visual aid for students and allows the instructor not only to demonstrate many principles of Raman spectroscopy and instrumentation, it also helps illustrate the concepts of calibration curves, blank subtraction, detection limits, and regression analysis. Portable and handheld spectrometers are easy...Read More
More often than not measuring heavy metal concentrations online in a process can be particularly challenging. This is especially the case when the sample contains several metals that interfere with each other during the measurement. Measuring multiple dissolved and total metals online simultaneously: Metrohm Australia has developed a new revolutionary...Read More
Metrohm’s Moisture Plus near-infrared (NIR) spectroscopy changes the way you do moisture analysis. It combines Karl Fischer titration, the gold standard for moisture analysis, with other analyses for different chemical and physical parameters into a single NIR measurement. This approach increases speed and lowers overall measurement costs. Most companies see...Read More
Software validations are long and tedious for everyone involved. Utilising a central software to control instrument and log data can save days of validation time, if not longer. For the pharmaceutical industry, LC and HPLC analysis is prevalent, making it logical to focus on a single software platform for instrument...Read More
As populations increase, the demand for clean water increases. Treatment of water allows the use of water sources that were previously considered unfit for human consumption. Whether removing salt in desalination plants, or removing bacteria and micro-organisms in ground water, treatment processes have come a long way. Testing these water...Read More
The shelf life of foods and beverages depends to a great extent on the packaging material. Metals are ideally suited for this purpose, as they can be coated with different passivating food-grade layers. Nethertheless, electrochemical measurements such as impedance spectroscopy (EIS) are required to monitor the integrity of the sealing...Read More
To find the best solution for your sample preparation task, Retsch’s application labs around the world offer free-of-charge test grindings and particle analyses. Out of more than 15,000 test reports generated in our labs, the most frequent applications have been collected in this application database. Retsch have been the market...Read More
EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects, due to the fact that the software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. Reduce errors...Read More
Written by specialists it describes in detail sieving methods and analysis procedures, such as sampling, sieve selection, wet sieving and more. A chapter explains evaluation and interpretation of results and another elucidates the secrets behind digital image analysis. I strongly recommend this Expert Guide to everybody involved in particle analysis....Read More
Spectroelectrochemistry is the combination of reaction-oriented electrochemistry with species-focused spectroscopy. A potentiostat/galvanostat is used to induce chemical changes on a surface or within a solution that are then monitored by changes in a spectrum. Spectroelectrochemistry (SEC) allows a more complete analysis of single and multiple electron-transfer processes. Spectroelectrochemistry especially useful...Read More
Portable Line potentiostats/galvanostats combine electrochemical research in the laboratory with on-site research using well-established electrochemical techniques. These small and affordable portable instruments enable you to develop applications for your specific research needs. Portable Line instruments are an ideal solution in many research areas, such as (bio)sensor, corrosion, or (bio)fuel cell....Read More
