Main text KRISS and NMIJ jointly coordinated the CCQM-K158 comparison on elements inorganic As in polished rice flour. The study comprised two parts, Part A B. Successful participation formal international comparisons is essential for documenting calibration measurement capability claims (CMCs) by national metrology institutes (NMIs) designated (DIs). specifically supports CMCs within food category, corresponding to sample matrix labeled "High organic content" new CC table broad claims....
The quality of analytical data coming from the analysis biological samples like blood, serum and human hair is fundamental importance for judging limit contaminants. Since this exposed to errors due sampling, sample preparation instrument, it important validate methods used such measurements. A method quantification lead, chromium, copper, magnesium zinc in blood using electrothermal flame atomic absorption spectrometer was established. Full validation done ensure suitability developed...
Main text The platinum group elements (PGEs) play an important role in reducing emissions from automotive vehicles through their use catalytic convertors but also for catalysis the pharmaceutical industry. immense economic value of (Pt), palladium (Pd) and rhodium (Rh) highlights importance highly accurate measurements. Therefore, there is a need National Metrology Institutes (NMIs) Designated (DIs) to demonstrate measurement capability this space. A pilot comparison (CCQM-P63) precious...
Cosmetics are used in practically all walks of life as a means improving skin and beautifying complexion. In recent years, more attention has been paid to the cosmetic safety. response safety issue, accurate measurement heavy metals cosmetics is, therefore, particularly important. NMIs from different countries should establish their chemical metrology traceability system this area, which includes both methods research certain CRMs development. It be noted that because matrix many is complex...
Accuracy and comparability of measurement results are vital to guarantee correct controlled process operational conditions. All these require reliable measurements based on reference materials whose certified values must be gotten by dependable metrological approaches agreeing the requirements ISO/ICE 17034 ISO guide 35 (ISO, 2016, Guide, 2017). The characteristics (CRMs), especially uncertainty their properties, position within traceability hierarchy items interest for quality assurance....
Matrix certified reference materials (CRMs) are versatile tools to support quality, correctness and credibility of measurement results.CRMs used provide the traceability results SI unit.Seven low alloy steel were developed by national institute standards (NIS), Egypt.Homogeneity is studied using x-ray fluorescence spectrometer (XRF) optical emission (OES).The characterization RMs was performed independent chemical methods as gravimetric methods, spectrometry, spectrometry atomic absorption...
