A new version of the ‘VERBA‐XRF’ mode was developed for the determination of the contents of principal elements with atomic numbers Z > 10 and SUM9, that is, the sum of the contents of complementary elements with Z < 9 in powder materials without alloying with borax. An original set of equations provides determination of the SUM9. Analysis was made on 120 samples: dust from electric filters, clay, clinker, gypsum, bauxite, slag, candle‐end, shale, schlamm and chalk. The results obtained in the determination of the elements Fe, Ti, Ca, K, S, Si, Al and Mg have relative standard errors of 1–2%. The availability of the value of the SUM9 provided the possibility of determining chemical compositions in samples. The content of mineral white in natural gypsum was calculated.
