Analytical determination of crude fibre in animal feed
Even animal feed is sold with a declaration about its contents. For quality assurance those substances of contents are continually examined. Utilized were the following FRITSCH instruments for the sample preparation
Sample analysis of maize kernels
Maize kernels, dressed, prepared as seeds, are subject to testing in regards to possible contents of genetically modified organisms (GMO). The necessity arises to test the seeds for possible properties of genetically modified contents. Optimal for the tests is the FRITSCH- Variable Speed Rotor Mill PULVERISETTE 14
Processing cocoa beans in the laboratory
The cocoa beans are exported world wide. The most important products which we as consumers come in contact with are cocoa beverages and chocolate. The most important characteristic trait for us is the taste. But before it becomes chocolate, the cocoa beans have to be roasted, peeled and cracked open. Very well suited for the further processing are several FRITSCH-Laboratory Mills
Scented toys – Analysing allergenic Substances
Relatively new on the market are scented toys. Not only do these substances smell good, but they also possess a more or less allergenic potential. Solved was this difficult task of the sample preparation without fragrance being lost with the FRITSCH Vibratory Micro Mill PULVERISETTE 0
Sample preparation for refuse derived fuels
Plastic, wood and shredded waste, are in times of rising crude oil prices very interesting additions to the classic fuels. Especially in the cement industry, the energy rich fractions from conditioning processes are readily burned along. Important is here the analytical evaluation of the materials. The following FRITSCH instruments are suitable for the sample preparation
Processing of soil samples for nutrient analysis or for radiologic measurements with the soil deagglomerator PULVERISETTE 8
Soil is the loose covering of earth’s topmost surface, which is practically always active. Downwards the soil is bordered by solid or loose rocks. Towards the top it is mostly bordered by a cover of vegetation, as well as the atmosphere. Where the topmost layer of soil is covered by water, lakes, rivers and oceans it is considered sediment rather than soil. Depending on perceptions and scientific discipline “soil” can be defined differently. Ideal for the sample preparation of soil is the FRITSCH Soil Deagglomerator PULVERISETTE 8
Comminution of Purple Moor-Grass
Especially in northern Germany occurs the Purple Moor Grass (Molinia Caerulea). Interesting for research are the absolute contents and the ratios of carbon and nitrogen in the plant material. For the determination of these values mostly carbon and nitrogen analyzers are utilized. The task was completed with the following FRITSCH-Mills
Tarpaper, Roofing-Bitumen... most people are only familiar with these materials in order to seal roofs
But what happens with this material when a building is torn down? Utilized are then the FRITSCH Cutting Mills
Liquid manure - waste product, supplier of nutrients or source of energy?
When consuming our cutlets we do not think about the unappetizing by-products which evolve during the meat production. Essential for the analytical analysis is the FRITSCH- Vibrating Cup Mill
Sample preparation of mineral animal feed
Many various different kinds of animal feed exist which differ in regards to each animal in composition, appearance and analysis. Nevertheless exact guidelines for its contents in regards to minerals, possible additives and unwanted ingredients exist. Essential for each animal feed is though, that the composition has to be inspected. Utilized for the sample preparation was a FRITSCH-Mortar Grinder
Chemical analysis of leather
During the processing of leather various chemical analyses have to be performed. Perfect for this task are the FRITSCH-Cutting Mills
Milling of leather for the sample preparation
Leather is almost always prepared in production facilities and also in testing institutes with Cutting Mills for analytical monitoring. Perfect for this task were the FRITSCH-Cutting Mills
Processing of silage for biogas
New ideas are necessary for the production of renewable energy sources and for the sample preparation a FRITSCH- Planetary Mill
Mycotoxins in nuts - generating of representative samples
Every year during the pre- holiday activities the use of nuts increases in order to prepare for the holiday baking. To a large degree unnoticed by consumers is the problem of a possible contamination of these foods with mycotoxins. For the sample preparation we recommend the Universal Cutting Mill PULVERISETTE 19
Drug testing via hair analysis
In order to proof the consumption of drugs (cocaine, cannabis products, amphetamines) even after long periods of time, hair is frequently analyzed. Details of the sample preparation
Analysis of lead in toys
Important and always current is the analysis of lead in toys for children. Details about the effective sample comminution with FRITSCH MILLS
