Analytical quality control

Analytical quality control refers to the set of procedures and techniques used to ensure that data obtained from analytical processes are accurate and precise within assigned values. This includes the use of reagent blanks, replicate samples, and certified reference materials to assess data accuracy and precision. It is essential to use suitable analytical quality control procedures for input and analysis of data to ensure reliable and trustworthy results.From: Handbook of Water Analysis [2019], Heavy metal contamination of street dust of Canton Sarajevo, Bosnia and Herzegovina – Health risk assessment [2022], Monitoring Bathing Waters [2019]

Recovery or “Spiked” Sample Procedures. A recovery procedure in which spiked samples are used provides a technique for the detection of systematic errors. The technique provides a basis for evaluating the applicability of a particular method to any given sample. It allows derivation of analytical quality control from the results, thus providing the basis for an excellent quality control program.

Analytical quality control, including reagent blanks, replicate samples and certified reference material was used to assess data accuracy and precision. Reagent blanks were prepared and analyzed in the same manner as the dust samples. The validity of chemical analysis was assessed by periodic analysis of the certified reference material (CRM) CTA-FFA-1 (Fine fly ash, Institute of Nuclear Chemistry and Technology, Department of Analytical Chemistry, Warszawa, Poland) which was treated in the same way as the dust samples. The detection limits (LOD) for Cd, Cr, Cu, Ni, Fe, Mn, Pb, Zn and V are 0.01, 0.15, 0.06, 0.11, 0.97, 0.17, 1.14, 0.71 and 0.89 μg/mL, respectively. All chemicals used for heavy metals measurements were of analytical grade or high purity.
