    Eigenschaften repräsentativ in den einzelnen Teil oder Analysenmengen wiederzufinden Quality control of coal The influence of sample preparation on elemental analysis results The most common types of coal lignite bituminous and anthracite are distinguished by their different chemical and physical properties The calorific value of coal can be determined by analyzing its carbon content for example with combustion analyzers In addition efficient management of the desulfurization plant requires control of the sulfur content Compared to the large amount of coal a typical laboratory sample consists of a 10 liter bucket or even more the sample volume required for analysis is fairly low only approx 1 g The standard DIN 51701 defines the sample amount to be tested as this relates to the particle size The bigger the particles are the more sample material is required 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 Recycled glass a valuable resource Today recycled glass is the most important resource for the glass industry The processed glass can be reintroduced to the melting process any number of times and made into new products In Germany currently up to 95 of recycled glass is used for producing glass which has various advantages energy saving less consumption of primary raw materials such as lime and silica sand and the reduction of landfill costs for waste glass 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 Sample Preparation of Solid Materials for the XRF analysis X Ray fluorescence is one of the most versatile methods to determine elements in a sample The material is exposed to x rays that cause each element to emit its own unique fluorescent x ray The subsequent analysis of the results is based on comparisons to standard samples with given chemical composition Representative results require adequate sample preparation The following situation is typical for many production plants After a routine quality check the production process is stopped or an already produced batch is suspended because the analysis results were not within the relevant critical values But does the tested product really deviate from the specifications The quality control managers are convinced of this because modern analysis instruments provide results with very low tolerances The sample in question was tested several times and the result was confirmed The question is
