Tips and tricks for dispersing statically charged or hydrophobic sample material for particle measurement, in order to ensure an optimal analysis. The computer is only as smart as its user. We all know this saying and it applies at least as much to high precision, fully automatic analytical instruments, such as the FRITSCH Particle Sizer ANALYSETTE 22 NeXT. Even though much is already done automatically here, it is important for the user to know a few tricks and tips, especially with samples that are difficult to disperse, in order to ensure an optimal analysis. Particle measurement of easy-to-disperse samples Many samples require special preparation for measurement due to their material properties. If dispersion is necessary to be able to measure the primary particles, wet dispersion is the ideal form for most samples. Preliminary tests must be carried out to check in which way the sample material can be wetted and dispersed. The liquid should wet the solid as spontaneously and completely as possible. In wet dispersion, the sample material is placed in a closed liquid circuit and continuously pumped through…

After almost 40 years as managing director of Fritsch gmbH, Robert Fritsch was bit farewell Robert Fritsch was bit farewell on his retirement on 1st January 2020. He looks back on times of modernization, economic growth and success. In 1920 the medium-sized family business was fund in Idar-Oberstein as a technical precious stones trade by Max and Alfred Fritsch. After the Second World War Willi and Paul Fritsch, sons of Alfred Fritsch, took over the management.

Distributors as well as consumer have a great interest in their products meeting quality standards. For chemical analysis and quality control is a diligent sample preparation as a prerequisite for a fine analysis essential, in order to observe the predefined critical values and tolerance values. Perfectly suitable for the comminution of nuts are the FRITSCH Cutting Mills. Consumer protection Food inspections concentrate on verifying harmful substances like toxins, heavy metals and non-permitted pesticides. The consumers trust that top limits of harmful substances are not exceeded and therefore contaminated products not sold. Nuts are considered a problematic product in food inspections since the shell gives no clue about whether the core has the adequate quality. The inside may contain fungal spores or toxins which simply can not be perceived from the outside. With defined methods, samples may be tested for their safety. Research and development in chemical analysis…

Generation of representative samples Detailed sample preparation of nuts according to regulation (EG) no. 401/2006 with tips, approaches and photos of the individual steps With the REGULATION (EG) no. 401/2006 of the COMMISSION of 23rd February 2006 binding standards for sampling procedures and analysis methods for the official testing of the mycotoxin content of food stuffs for example nuts was established. The task in the laboratory is as follows: „Each laboratory sample is to be prepared with a verifiable procedure which guarantees a complete homogenisation, ground finely and meticulously mixed. “ The regulation allows two means: 1. The nuts in the shell may be peeled and the aflatoxin content is to be determined for the edible share. This might be still feasible for peanuts. With walnuts, filberts or almonds this is very problematic though. 2. The other possibility is to use the nuts „inside the shell“ for the sample preparation. The task: 10 kg peanuts, walnuts, filberts, Brazil nuts…

Often an extreme challenge Probably one of the most difficult tasks was the fine distribution of pure liquid mercury in a mixture of fine solid metal powders. Already during the manual mixing with a spatula, with careless work methods without a problem up to 3 mm large amalgam grains were produced. The solution was added to the Mortar Grinder PULVERISETTE 2, with an agate grinding set and special adjustments for the minimizing of the application of energy found. From the area of mixtures liquid – solid is the production of filled pastes to be mentioned. Especially challenging here is to add as much as possible solids in the high viscosity organic phase. An additional example for this is, when one has to add to organic binder (for example synthetic resin or varnish or in the simplest case oil) fine metallic, ceramic or inorganic powders. High viscosity pastes evolve which can be compared with shoe polish in a tube. Experts often talk about filled composite materials. Often the increase…

Straw, hay, dried plants; herbal teas are mostly very bulky samples. An average shopping bag contains 300 g straw or expressed like this: 100 g of uncomminuted straw take up the space of 1 to 2 litres. These materials are very voluminous. For the comminution only a cutting mill with a high rotor speed can be considered. So the choice is between the Cutting mill PULVERISETTE 15 and the Universal Cutting Mill PULVERISETTE 19. The reasonably priced Cutting Mill PULVERISETTE 15 is to be recommended if: • only a few samples per week are to be comminuted • the sample amount is small • the linear expansion has been reduced via chaffing for example • if a low carry over of sample material to the next sample is tolerable • more time for cleaning is available Are the recommendations in regards to cleaning and expenditure of time higher though, the Universal Cutting Mill PULVERISETTE 19 is implicitly to be recommended. Extremely positive effects…
