Abstract A simple and fast method for the determination of total concentrations of Ba, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, P, Sr, and Zn in wheat crispbreads using inductively coupled plasma-optical emission spectrometry was developed. Initially, three different sample preparation procedures, i.e., microwave-assisted digestion in an HNO3 and H2O2 mixture and solubilization in aqua regia or tetramethylammonium hydroxide solution were compared. The performance of these procedures was evaluated for precision, accuracy, and LOD of the elements. It was established that the application of aqua regia allows determining elements with LOD within 0.1–42 ng/mL, precision of 0.2–4.1%, and accuracy better than 5%. Furthermore, good agreement between measured and certified values of a National Institute of Standards and Technology certified reference material of wheat flour (SRM 1567a) was found. It was confirmed that the proposed method could be used successfully as an alternative to microwave-assisted acid digestion in routine multielement analyses of wheat crispbreads.
