- a target concentration of the first component is that concentration of the first component in the manufactured article, when used in the prescribed proportions in the manufacture of the article.
- An actual concentration is an analytically or metrologically determined or calculated concentration of the first component in the manufactured article in which the first component is actually present.
- the terms of the target concentration and the actual concentration can also be used as Sollg. Actual proportions of the first component, eg. In% (percent), volume%, mass% or mol%, of the article.
- An analyte is an element or compound contained in a sample that is to be said to be meaningful by analysis. As analytes, it is preferable to select elements or compounds which can be determined very accurately with respect to their contents by the method of X-ray fluorescence analysis.
- the analytes should be available on an industrial scale and must not be economically expensive or only slightly more expensive. In addition, the analytes should be as colorless as possible and not or only negligibly affect the coloring.
- the properties of the article should be neutral to the analytes in the user concentrations.
- the analytes are non-toxic and are not otherwise harmful to health or the environment.
- the analytes intended for use should be available in product qualities which, due to their small particle size, also enable applications in all thermoplastic moldings, including in the area of fibers and films.
- the analytes must have small particle sizes ranging from a few microns to nanometers.
- the analytes can be detected in low concentrations in view of a detection to be carried out by means of X-ray fluorescence spectrometry and the analytes are not or only rarely present in organic polymer materials or additives such as pigments, additives or fillers.
- the elements strontium (Sr), zirconium (Zr) and tin (Sn) to be used in the process according to the invention can be used in elemental form, in the form of compounds of the elements or in combinations thereof. Preferably, no more than three elements and / or compounds are used in a first component.
- Compounds may be, for example, strontium carbonate, zirconium silicate and tin oxide.
- the method of X-ray fluorescence analysis is used essentially for the detection and determination of chemical elements. With regard to the technical design of the detection of X-ray radiation, two principles are used:
- the measured fluorescence spectra can be graphically displayed and output or further processed via digital processing processes on the personal computer.
- the K, L or M lines characteristic of the analytes preferably the K a line, K ⁇ line, are used.
- X-ray fluorescence spectrometers in the detection of the analytes added has several advantages. On the one hand, a non-destructive measuring principle is used. On the other hand, no or relatively simple sample preparations are required and there are modern evaluation routines (fundamental parameter methods, Compton correction) available, which usually allow a sufficiently accurate determination of the chemical elements. In many devices also a relatively simple operation is given.
- the measurement can even be carried out on site. In many cases, disassembly of the parts to be examined or a different preparation is unnecessary. The use value of the article remains fully intact. In other cases, the part to be examined by disassembly be exposed. In any case, no separate chemical sample preparation z. B. by a chemical digestion process necessary. As a rule, the object to be examined remains fully usable even after the measurement.
- Another advantage of the method according to the invention is that the type of analyte or analytes used and their concentrations are known only to initiated persons. For contractors, such. B. thermoplastic-producing and masterbatches or polymer compounds processing companies, the presence, nature and concentration of the analytes is not known and can only be determined by extensive studies.
- the inventive method can be used to verify compliance with a predetermined target concentration of a first component in an existing thermoplastic article.
- it can also be used to perform an assignment of the article to a manufacturer of the article on the basis of the actual concentrations.
- the respective manufacturer-specific desired concentrations of the analytes must be known.

- the masterbatch should contain 3 - 4% by mass in the PP material.
- a masterbatch dosage of 8.46 mass% was determined by RFA.
- doses of 8.40% by mass and 8.00% by mass were determined. Obviously, the dosage of the masterbatch was far too high in the manufacture of the auto part.
- a Masterbach for equipping a greenhouse film contains 10% by mass of strontium carbonate as an analyte.
- the preparation of the film should be carried out at a dosage of 1, 0% by mass of the masterbatch.
- the actual concentration of the analyte strontium carbonate was therefore 0.1% by mass.
- test plates with contents of 0.01; 0.02; 0.05 and 0.09 mass% strontium carbonate used.
- the dosage was determined on a sample of ten film layers on top of each other and on a melt tablet. By means of RFA, actual concentrations of strontium carbonate of 0.096% by mass were found directly at the film coating and 0.1% by mass in the melt tablet.
- the calculated dosages of the masterbatch were therefore 0.96% by mass and 1.0% by mass, which corresponds to the desired concentration.
- a polymer compound for equipment for permanently antistatically treated containers was doped with 0.1% by weight of strontium carbonate.
- strontium carbonate To calibrate the strontium content, tensile bars with 0; 0.05; 0.1 and 0.2 mass% strontium carbonate used. The modulus of elasticity dropped from 1 601. 8 N / mm 2 for the non-equipped test bar to 1531.5 N / mm 2 for the equipped test rod. The tensile strength remained constant at around 28.6 N / mm 2 and the notched impact strength dropped from 26.6 to 24.8 mJ / mm 2 .
- the measurement on the tensile bar doped with a target concentration of 0.1% by mass of strontium carbonate gave an actual concentration of 0.102% by weight of strontium carbonate. In accordance with the very small deviation from the target concentration and the determined actual concentration, relatively small additions of foreign materials to the present polymer compound should also be detectable when tested by the method described.
