A procedure for the digestion and analysis of quartz samples was developed to measure trace element concentrations in natural quartz. The certified glass sand reference material UNS‐SpS was chosen to assess the precision, accuracy and detection limit of the analytical method. Quartz was digested with HF/HNO 3 in a closed glassy carbon vessel and analysed by means of quadrupole ICP‐MS with external calibration. Analyte concentrations of the sand UNS‐SpS were compared with certified and other values from the literature. The abundances of a number of elements (Pr, Gd, Ho and Er) in the reference material are reported here for the first time. The procedure was then applied to three quartz samples from different geological settings to show that trace element data by ICP‐MS can distinguish the origin of the sample.
