[TXRF technique and quantitative analysis of mollusc teeth].
Total reflection X-ray fluorescence (TXRF) analysis technique and the instrument with a short path, high efficiency, low power and small volume are briefly presented. The detection limit of the system are at pg-level for Cu and Mo target excitation. Teeth of a marine mollusc were measured quantitatively and the spectrum and analysis results were given.
