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 why the product does not match the specifications although the production parameters have not been changed in any way.
The possibility that the tested product is indeed deficient cannot be excluded. However, it is often not the product itself which causes irregular analysis results but a lack of understanding of the steps which come before the analysis.
Comparative investigations on spinning rifflers
The influence of the degree of mixing of the material and the influence of the operating data of the apparatus were investigated in two spinning rifflers.
Fine Tuning Sieve Analysis for Accurate Particle Size Measurement
All to often, this useful method is overlooked. But if followed, these principles deliver accurate and reliable results at an affordable price.
Put the squeeze on
Sieving is cost effective for particle sizes greater than 75 μ, although the technique can be used for some materials of smaller size if the method can be validated. Assuming the relevant standards and clean, wellmaintained equipment that conforms to the standards are used, sieving can provide an accurate and reproducible measure of particle size distribution within a sample.

The preparation of samples of solid substances for spectroscopic analysis
X-ray fluorescence spectrometry is one of the most versatile multi-element methods of chemical analysis. The technique is based on excitation of fluorescent radiation from a sample by bombarding it with high energy X-ray quanta and subsequent study of the characteristic X-ray radiation emitted by its elements.
Vergleichende Betrachtung zweier Rotationsprobenteiler-Prinzipien
Zur Qualitätssicherung und Steuerung einer Produktion beschränkt man sich auf die Untersuchung von Teilmengen (Analysenmengen).  Ziel der Probenteilung muß es daher sein, die in der Gesamtmenge eines zu untersuchenden Stoffes heterogen verteilten Eigenschaften repräsentativ in den einzelnen Teil- oder Analysenmengen wiederzufinden.
