Grinding tool for comminution of the smallest quantities

WITH a footprint of just 20x30cm and a weight of 7kg, the Fritsch Pulverisette 23 mini-mill is promoted as the ideal tool for reducing small volume samples for laboratory analysis by X-ray fluorescence and infrared spectroscopy. Typical applications of the…

Improved grinding of hard and fibrous material

FRITSCH says that its new, completely modified Pulverisette 9 vibrating cup mill offers practical advantages when hard, brittle, or fibrous material must be ground quickly to analytical fineness. It is suited to fast sample preparation for spectroscopy, ore analysis in…

Preparing samples of selenium for analysis

SELENIUM, element 34, presents a sample preparation challenge, as outlined below by certified chemist Wieland Hopfe, application consultant for Fritsch. Selenium is one of the less commonly known elements, appearing on the periodic table immediately below sulphur. It is an…

Particle sizers get Analytica launch

FRITSCH is using Analytica 2012 to launch two new models in its Analysette range. The two new Analysette 28 particle analysers measure the shape and size of particles in powders and bulk solids, and in suspensions and emulsions. The Analysette…

Preparing purple moor grass for elemental analysis

PURPLE Moor Grass, Molinia caerulea, is a common plant in northern Europe and is of scientific interest for the ratios of carbon and nitrogen in contains. The analysis of the material is itself straightforward, but preparing samples for analysis has…

Optimised grinding of temperature-sensitive samples

THE COMMINUTION of difficult samples, like temperature-sensitive powder coatings and plastics, or materials with intrinsic moisture such as tea or herb leaves, can present a problem for some sample preparation mills. Fritsch says that its Pulverisette 14 variable high speed…
