    to make even the smallest traces of sample components detectable Despite this development sample preparation which is carried out prior to the actual analysis is frequently neglected Errors caused by lacking accuracy in sample preparation have a much bigger impact than errors made during analysis Just like an iceberg which is mostly hidden under water only a small part of the sum of errors is perceived whereas the major part of potential errors is not taken into account fig 1 One of the reasons may be the fact that sampling and sample preparation have always been done in a traditional way which has become a routine over the years and is no longer considered as having a critical influence on the subsequent analyses Detection of genetically modified organisms GMO in food and feed Genetic engineering opens up new possibilities in areas such as medical research development of alternative fuels or global food supply It is used to modify the characteristics of plants in order to increase the crop yield improve defense against predators pesticides or draught but also increase concentrations of essential vitamins However with regards to food the use of genetic engineering is a fairly controversial issue Moreover food and feed stuff are subject to rigorous quality control processes to prevent humans and animals from potential harm Sample Preparation and Analysis of Arsenic in Rice Considerable care must be taken when analyzing a sample like rice in order to achieve an accurate result The major source of error when analyzing a bulk material comes not from the analytical measurement itself but from the sample handling i e sampling sample division grinding digestion etc Renewable energies on the rise Sample preparation of vegetable based raw materials with laboratory mills Thanks to the increasing usage of biomass as a source of energy the analysis of these materials in the context of R D and quality control gains importance too Due to the complex properties of plant materials adequate sample preparation can be rather a challenge Sample preparation of feeds and forage for NIR analysis The feed quality has a decisive influence on the productivity of livestock farming However high quality forage considerably adds to the costs of stock breeding Consequently economic considerations focus on the quality and quantity of the components used in the production process This includes reliable analyses of feedstuff and ingredients from receipt of goods to final inspection as the best way to ensure a balanced feeding of the animals while keeping cost and profit orientation in focus Near Infrared Spectroscopy NIR is the most important analytical method for the determination of protein content moisture fat and ash in feeds and forage The advantage over classical methods such as Kjeldahl is the simultaneous determination of several parameters Moreover NIR spectroscopy is a quick method which requires neither consumables nor reagents Representative Analysis Results Require Adequate Sample Preparation A faultless and comparable analysis is closely linked to an accurate sample handling Only a sample representative of the initial material can provide meaningful analysis results Rotating dividers and rotary tube dividers are an important means to ensure the representativeness of a sample and thus the reproducibility of the analysis Correct sample handling consequently minimizes the probability of a production stop due to incorrect analysis results Thus correct sample handling is the key to effective quality control CryoMill Cryogenic grinding was never more convenient or efficient Some sample materials have properties which make size reduction at ambient temperature impossible If for example very elastic materials need to be ground or volatile components have to be preserved for further analysis it is essential to carry out cryogenic grinding The use of liquid nitrogen helps to embrittle the sample thus improving its breaking properties and preventing volatile substances from escaping due to the frictional heat produced by the grinding process Powerful Cutting Mill The SM 300 excels especially in the tough jobs where other cutting mills fail It has a freely selectable speed range from 700 to 3 000 rpm with high torque The mill is convenient to operate and easy to clean Reliable and extremely efficient sample preparation in the laboratory is now guaranteed with the SM 300 Renewable energy Wood residues from forestry work and wood processing are usually processed to wood chips These can be used in different ways depending on the type of wood bark and residual moisture for example as raw material for chipboards or as substrate for the cultivation of mushrooms The major part however is used for energy generation The quality of the wood chips can vary significantly depending on their origin and condition Trade and industry are interested in the percentage of dry matter and in the calorific value of the chips as the price calculation depends on the water contents of the product With the analysis result representing an important economic factor the representative and reproducible sample preparation gains importance too Are cereal bars really healthy Food manufacturers often promote their products as light or such as in the case of cereal bars healthy If that is actually true can only be verified by analyzing the nutritional values a procedure which forms an important part of food quality control The values of fat saturated fatty acids sugar and salt which are printed on the packaging represent an average of the content of each substance and relate to 100 ml respectively 100 g of the product The cereal bars consist of a heterogeneous mixture of ingredients nuts raisins oat flakes etc therefore the thorough homogenization of the sample is required to obtain meaningful analysis results From cacao tree to chocolate bar The way from the cacao tree to the chocolate bar is a long one Due to the many processing stages harvest fermentation drying cleaning roasting pre crushing and finally grinding the cocoa nibs to liquor from which cocoa powder and cocoa butter are pressed there may be significant variations in the quality The quality control process not only includes testing the innocuousness of the

    a basis for the regeneration of bone substance Various RETSCH mills are suitable for the preliminary and fine grinding of human bones as well as bioceramic materials Representative Analysis Results Require Adequate Sample Preparation A faultless and comparable analysis is closely linked to an accurate sample handling Only a sample representative of the initial material can provide meaningful analysis results Rotating dividers and rotary tube dividers are an important means to ensure the representativeness of a sample and thus the reproducibility of the analysis Correct sample handling consequently minimizes the probability of a production stop due to incorrect analysis results Thus correct sample handling is the key to effective quality control CryoMill Cryogenic grinding was never more convenient or efficient Some sample materials have properties which make size reduction at ambient temperature impossible If for example very elastic materials need to be ground or volatile components have to be preserved for further analysis it is essential to carry out cryogenic grinding The use of liquid nitrogen helps to embrittle the sample thus improving its breaking properties and preventing volatile substances from escaping due to the frictional heat produced by the grinding process What hair reveals The detection of illegal drugs and pharmaceuticals is important in areas such as forensic science traffic or competitive sports Chemical substances can be detected in blood saliva urine and hair the latter having the advantage of storing the substances for a fairly long period depending on the hair length In addition to the tracing of drug abuse hair samples are also used for DNA analysis What Hair Reveals The detection of illegal drugs and pharmaceuticals plays a role in various fields for example in forensic science road traffic accidents in competitive sports or at the workplace Chemical substances can be detected in blood saliva urine and in hair Hair has the great advantage of storing the substances for a long period which means that detection is still possible several months after consumption of the drug In addition to the detection of drugs hair samples are also used for DNA analysis as well as for the analysis of heavy metals and minerals Using the CryoMill for samples with volatile substances For the size reduction of many materials it is more suitable to use a cryogenic mill than a laboratory mill which operates at room temperature The sample is embrittled by liquid nitrogen which improves its breaking behavior when submitted to impact pressure and friction moreover volatile components of the sample are preserved The RETSCH CryoMill is not only the most modern and safest cryogenic mill in the market it also provides excellent grinding results Rapid and efficient disruption of yeast cells with the Mixer Mill MM 400 Cell disruption of bacteria yeast filamentous fungi or microalgae is a standard procedure in basic biological research applied biotechnology or medical research to get access to nucleic acids DNA RNA or cell proteins For the isolation of DNA or RNA usually less than 1 ml of cell material is
