ABSTRACT:
An apparatus is disclosed which is used for total reflection fluorescent X-ray analysis on a liquid drop-like sample containing very small amounts of impurities. The apparatus comprises a heat-resistant thin sheet containing an element or elements, as a principal component, not detected on total reflection fluorescent X-ray analysis and an x-ray source directing an X-ray as an incident X-ray at a liquid drop-like sample put on the sheet and containing very small amounts of impurities whereby the liquid drop-like sample is evaporated to a dried solid for the total reflection fluorescent X-ray analysis to be performed there.
