3.1 Samples
Samples and their preparation are a delicate part of the analytical procedure. A large number of parameters are involved in the sampling, sample shaping and sample surfacing processes, and their impact on assay quality should not be underestimated.
The spectrometrist must also take into account the origin of the metal, as a sample taken during the manufacturing process and a certified reference material are not completely similar in terms of structure and distribution of constituents. Each type of sample has its own specific characteristics. The local and destructive nature of SEO analysis means that, to obtain a correct result, the sample must be representative of its original medium (liquid or solid), and the part consumed during sparking must...

Cost of equipment
Depending on the laboratory's analytical needs, the cost of purchasing a spectrometer can vary considerably, as the purchase price depends on the number of analytical lines. It is therefore preferable to set a price range for a spectrometer equipped with 20 fixed channels and a single spark excitation source. So-called low-end equipment with a limited number of 20 or so elements ranges from 45 to 75 kE, while the upper...
