The quantitative analysis of 16O in near-surface regions of samples can be performed with 16O(3He,p)18F reaction. The cross section for this nuclear reaction in SiO2 samples has been determined at a reaction angle 135 for 3He energies in the laboratory frame between 1800 keV and 6100 keV. A relation between the number of protons collected as a result of the nuclear reaction and the amount of oxygen in tungsten samples has been determined.
