Tiivistelmä

We have investigated the suitability of the low-power X-ray spectrometer SPARK 1 to the determination of the trace elements. Thanks to the alternation we made to the sample cuvette the pressed samples can now be used and this improves the usability of the equipment. The best diluting and binding agents for the samples were teflon powder and potassium iodide. We made investigations using sewage sludge, bottom sediments of the lakes, fertilizer mixtures, pure moss peat and moss peat with various amounts of fertilizer added. The results were in accordance to the results obtained directly with AA-spectrophotometry with known addition method. The equipment suited well for the determinations mentioned above. The additional advantages are low power consumption, minimal scatterad radiation and no need of cooling water. These features replace the disadvantages due to the limited amounts of the elements that can be determined as well as the scattered radiation during copper determination.
