We report self- and air collisional broadening coefficients for the H2O line at 7299.43 cm?1 corresponding temperature a range spanning 293–573 K. New laser spectroscopic setups specifically designed this purpose have been developed are described. The parameters reported here in good agreement with those values HITRAN 2020 database, but uncertainties reduced by factors of about 4, 1.3 4.4 self-...
The measurement uncertainty budget should combine the uncertainty of higher order references, the uncertainty of commercial system calibration, the system imprecision and individual laboratory performance in terms of variability. Here we recommend that no more than one third of the total uncertainty budget, established by appropriate analytical performance specifications, is consumed by the unc...
thyroid-stimulating hormone, and cardiac troponin I (cTnI) is underscored by their routine use in the diagnosis, prognosis, monitoring, and management of disease, and their incorporation into professional guidelines. Standardization is difficult for proteins because there are few reference measurement procedures for these analytes, few primary (pure substance) reference materials (RMs) have bee...

traceability is a basic requirement for the most of products from the viewpoint of governments and customers. it has base of quality systems and supports integration of supply chain information systems. this paper has presented a holistic model for supply chain traceability through structural equation modeling. this model will support recall of products, quality assurance requirements, improve ...
This annotation addresses the concepts of nanometrology and nanoanalytics, highlighting importance measurements their metrological traceability at nanoscale. The interdisciplinary nature both analytical chemistry nanotechnology is emphasized. requires joining efforts different fields, e.g. chemistry, medicine, pharmacy, biology, materials science engineering, to face with guarantee challenges t...
The method of Raman spectroscopy (RS) is widely used for timely metrological support technological lines the industrial sector in chemical, medical and pharmaceutical, food, as well criminalistics forensic examinations. wide application requires use specific tools, namely, measures calibrating spectrometers microscopes according to spectrum shape (i. e. relative spectral sensitivity). purpose r...
