The different properties of ground and unground samples when analysed with NIR are demonstrated with grains of wheat. The samples were analysed 10 times, the spectrometer was refilled for every measurement. The wheat grains were previously ground in RETSCH’s cyclone mill TWISTER. The results show a considerable difference between ground...Read More

Metrohm has just released its new 914 benchtop and portable combined pH/Conductivity meter. Metrohm’s new 914 pH/Conductometer is a really easy-to-use measuring instrument for routine operation in the laboratory and on the road. pH (or mV) and conductivity (or TDS, salinity) and temperatures can be measured in parallel and output to...Read More

Ammonia and amines in ambient air: straightforward collection and subsequent analysis by ion chromatography. In a paper recently published in Atmospheric Measurement Techniques, Dawson et. al. present a novel technique for measuring gas-phase ammonia and amines in ambient air. Their technique uses a weak cation exchange resin as a substrate...Read More

Combustion Ion Chromatography (CIC) extends the range of ion chromatography to all types of combustible samples. In CIC the samples are first digested under an argon atmosphere in the oven unit and then burnt with oxygen. In the 920 Absorber Module, the resulting gaseous compounds are passed into an absorption...Read More

Serrated blades are now available for GM 200 and GM 300. The serrated knife for the Retsch GM Knife Mills will lead to much better results (faster and finer) for cutting through samples like meat – including fat, gristle and crust – or whole fish much faster and easier for...Read More

The new pH meters: See the video. Metrohm presents the 912 Conductometer, the 913 pH Meter and the 914 pH/Conductometer, a new generation of meters for pH and conductivity measurement. The new pH meters are every inch a «Metrohm» – flexible, robust, reliable, and ingeniously simple to use. Advantages of...Read More

The new 913 pH meter from Metrohm, benchtop version, a nice modern addition to any food lab, big or small. Metrohm has just released their new range of benchtop and portable pH meters, or indeed combined pH/Conductivity meters. The 914 additionally gives the user conductivity measurement. The 913 pH Meter...Read More

The preparation of a mixture of organic and inorganic samples holds some difficulties: whereas sand, clay and stones can usually be ground to homogeneous samples with suitable laboratory mills, the high energy input can cause samples with organic components such as fat or starch to cake. Waste water treatment laboratories...Read More

Gold micro-wire electrode for voltammetric determination of inorganic arsenic and mercury in waters. Voltammetry using a scTRACE Gold sensor offers a simple, highly affordable alternative to the spectroscopic determination of arsenic and mercury in drinking water and seawater. The scTRACE Gold is a combined sensor: a gold micro-wire working electrode,...Read More

Battery energy: Research on storage of renewable energy – (Photos: Hideki Kimura, Kouhei Sagawa and others). Scientists from Dr. Sascha Nowak’s group at the University of Münster (Germany) are doing research on electrolytes for lithium ion batteries. For the development of a separation method, they used and compared three ion...Read More
