Quality control of nuts
Quality control of nuts
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.

CHARACTERISTICS OF SAND  AND CRITERIA FOR ITS COMMINUTION
CHARACTERISTICS OF SAND
AND CRITERIA FOR ITS COMMINUTION FROM CONSTRUCTION MATERIAL TO SEMICONDUCTOR TECHNOLOGY On planet earth sand is a very common unconsolidated sedimentary rock. It is characterized by a particle size between 0.063 and 2.0 mm. The mineral composition can vary extremely. Many occurrences consist of quartz respectively silicon dioxide (SiO2). Due to its physical and chemical characteristics sand is mainly used in the construction and glass industry. The analytical evaluation of the chemical composition and therefore the aptness for the intended uses make the comminution of quartz sand a prerequisite. FRITSCH offers a wide spectrum of suitable mills for this. For the characterization of the particle size distribution, FRITSCH offers sieve shakers and instruments for particle sizing via static laser scattering as well as instruments for the dynamic image analysis. With these technologies, the tracking and optimization of the comminution processes can be excellently accomplished. COMPOSITION OF SILICON

Production of mixtures on a laboratory scale Often an extreme challenge
Production of mixtures on a laboratory scale
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

One Mill – Many Possibilities Now even more efficient with the Fritsch cyclones
One Mill – Many Possibilities
Now even more efficient with the Fritsch cyclones The Fritsch Variable Speed Rotor Mill Pulverisette 14 classic line is the ideal mill for fast, effective comminution of soft to medium-hard, brittle and fibrous materials as well as temperature-sensitive samples – proven worldwide for the use in trace analysis. The motor speed can be varied between 6,000 and 20,000 rpm in increments of one-thousand – making it possible to adapt the mill to each specific application. An automatic speed compensation feature ensures an ideal adaptation of the grinding to the specific comminution behaviour of the sample. At the same time, reduces the fast, effective grinding through the efficient air routing inside the Pulverisette 14 classic line significantly the thermal strain on the sample. Efficient cooling The ingenious air routing of the Pulverisette 14 classic line ensures a constant airflow to cool the rotor, all motor components and the grinding material in the collecting vessel. At the same time, a large fan blows the

Get to know the fastest and safest Planetary Ball Mills on the market
Automatic grinding bowl clamping, imbalance control and comminution down to the nano range FRITSCH’s premium line Planetary Ball Mills Pulverisette 5 and 7 can grind, alloy, mix and homogenize reliably at bowl speeds of up to 2200 rpm. They let you effortlessly grind hard, medium, soft, brittle and moist samples down to a final fineness of < 100 nm in a very short time. Sample quantities of 1 to 60 ml (Pulverisette 7) or 15 to 450 ml (Pulverisette 5) can be processed simultaneously at the two grinding stations. The planetary mills premium line work particularly fast thanks to the high bowl speed of up to 2200 rpm and achieve a final fineness of up to < 100 nm in 3 minutes. The easy insertion of the grinding bowls and the blockage of the start in case of impermissible operating conditions make the Planetary Mills in combination with the automatic grinding bowl clamping system particularly user-friendly and safe. For both wet and dry grinding, the process is easy to start due to the guided positioning of the grinding bowl and the automatic bowl detection

High-Tech Particle Sizing Reproducible Analysis of particle shape and size
High-Tech Particle Sizing
Reproducible Analysis of particle shape and size Whether in the field of production and quality control, research, development or the analytical laboratory, particle measurement is essential in many areas. This requires reproducible results, as with the Fritsch particle Sizers. But the choice is not always easy and must be specially adapted to the application. You can distinguish between different measuring principals. On the one hand for example the Static Light Scattering, ideal for particle sizing from 0.01 to 3800 µm. On the other hand for example Dynamic Image Analysis, for analysis of particle shape and size in an extra wide measuring range of 20 µm – 20 mm. Static Light Scattering With the completely revised Analysette 22 NeXT you choose according to your requirements: The Analysette 22 NeXT Micro with a measuring range of 0.5 – 1500 μm for all typical measurement tasks or the high-end instrument Analysette 22 NeXT Nano with an extra wide measuring range of 0.01 – 3800 μm for maximum precision

Comminution of Nuts Generation of representative samples
Comminution of Nuts
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

Foodstuff Production A culture of contradictions?
Foodstuff Production
A culture of contradictions? Again and again consumers are confronted with scandals in the foodstuff industry. The latest case is the Fipronil egg scandal in the laying hen farming in the Netherlands and in Lower Saxony (Germany). What actually do foodstuff producers and marketers do to avoid such cases? A lot, if you believe the rising costs in the area of modern foodstuff analysis. So during the last decades, always newer and more sophisticated processes will be and were developed with the most sensitive detection thresholds (ELISA, PCR or the mycotoxin analysis) for quality control, in order to lower the number or even eliminate such scandals and the potential danger for consumers. So now, in the context of these analytical processes again and again, methods for sample preparation of the most diverse matrixes were developed. Because especially food- stuffs and the raw materials, respectively convenience products are often composed clearly more heterogeneous like all other substance groups. Especially
