Proper Sampling It is always surprising how the market for high-precision, fully automatic analysis equipment is constantly growing, but so little importance is placed on the sampling techniques and preparation, which are at least as important as the actual equipment. One of the most frequent errors encountered in an analysis occurs already when the sample is obtained and is introduced into the analysis process from the very beginning. Process technicians are consistently amazed at how frivolously samples are taken and how easily the analyses results obtained are accepted without question. Deviations in repeated measurements often give rise to doubts about the measurement equipment, but the cause of the error lies deeper: inhomogenous sampling. The results are only reproducible if the analysed sample is highly representative of the material being tested, in other words, if the sample taken is equivalent to the entire material batch.
