Reducing plant power consumption with FC Bond index testing. Around half the energy used in most material processing plants is consumed in grinding. An introduction to the new range of Retsch testing equipment. Usually power consumption is the single biggest operating cost item and good energy utilisation is critical to...Read More

Protein and IC, now with simple sample preparation. Fats, proteins and oils provide challenges for analysis with ion chromatography. Fats and oils generally mean a non-aqueous sample, and all sample must be aqueous. Proteins provide a challenge by blocking columns and being difficult to filter. Historically, these samples either have...Read More

Limited to one application on your IC? Not here!  Instrumentation is a big investment for any laboratory, so you want to get as much out of your instrument as possible. While some laboratories have high enough throughput to dedicate instruments to a specific applications, many do not. Which makes flexibility...Read More

Raman is a fast alternative to the typically performed HPLC, FT-IR, colorimetric, and time consuming wet chemical identification of structurally similar sugars. Metrohm true handheld Raman spectrometer is perfectly capable of identifying of sugars such as D-galactose, D-glucose, D-maltose, D-mannose, D-sorbitol, fructose, sucrose and inositol. Rapid and non-destructive determination takes...Read More

Which titration suits your requirements best? Surfactant analysis does not follow the standard titration application profile. Anionic surfactant, cation surfactant, non-ionic surfactant, dual-phase titration; each has it’s own intricacy and fine-tuning. It is enough to make your head spin. Where do you start for the best analysis method? How do...Read More

Correlation plot of the predicted Heparin sodium product strength by NIRS versus the laboratory values. Displayed are the training data (blue) and validation data (turquois). Heparin is a glycosaminoglycan used as an anticoagulant for therapeutic uses. It can either be used directly for humans given by injection or used as...Read More

Keeping our kids safe and healthy Low levels of perchlorate in our diet will have little short-term effect for healthy adults. For children, however, the negative effect on brain development can be considerable. Perchlorate directly effects the uptake of iodine by the thyroid. In adults, this can have an effect...Read More

Metal screen-printed electrodes are promising, cost-effective SERS substrates. Metrohm Dropsens White Paper: In this white paper Alejandro Junquera Pérez, Pablo Fanjul Bolado, David Hernàndez Santos demonstrate the time resolved Raman spectroelectrochemistry measurements with screen-printed electrodes. The instrument used combines in a totally integrated box: a 785 nm laser source, a...Read More
