Background: Immunoassays allow the specific detection and quantitation of biological molecules in complex samples at physiologically relevant concentrations. However, there are concerns over comparability such techniques when same assay is performed by different operators or laboratories. An international intercomparison study was to assess uncertainty involved estimation a protein cytokine concentration using fluorescent ELISA.
CCQM-K120.a comparison involves preparing standards of carbon dioxide in air which are fit for purpose the atmospheric monitoring community, with stringent requirements on matrix composition and measurement uncertainty CO 2 mole fraction. This represents an analytical challenge is therefore considered as a Track C comparison. The will underpin CMC claims calibrations services matched to real air, over fraction range 250 μmol/mol 520 μmol/mol. CCQM-K120.b tests core skills competencies...
Forensic application of carbon isotope ratio measurements honey and protein to investigate the degree adulteration with high fructose corn syrup or other C4 plant sugars is well established. These must use methods that exhibit suitable performance criteria, particularly regard measurement uncertainty traceability - low levels can only be detected by result in suitably small uncertainties such differences 1‰ less reliably detected. Inter-laboratory exercises are invaluable assess state-of-the...
Under the auspices of Organic Analysis Working Group (OAWG) Comité Consultatif pour la Quantité de Matière (CCQM) a key comparison, CCQM K55.c, was coordinated by Bureau International des Poids et Mesures (BIPM) in 2012. Twenty National Measurement Institutes or Designated and BIPM participated. Participants were required to assign mass fraction valine present as main component comparison sample for CCQM-K55.c. The samples prepared from analytical grade L-valine purchased commercial supplier...
The first key comparison on carbon dioxide in nitrogen dates from 1993–1994 (CCQM-K1.b). Since then, numerous national metrology institutes (NMIs) have been setting up facilities for gas analysis, and developed claims their Calibration Measurement Capabilities (CMCs) these type mixtures. In the April 2005 meeting of CCQM Gas Analysis Working Group, a policy was proposed to repeat comparisons stable mixtures every 10 years. Consequently 2007 CCQM-K52 'Carbon synthetic air' carried out. This...
The CCQM-K82 comparison was designed to evaluate the degrees of equivalence NMI capabilities for methane in air primary reference mixtures range (1800 2200) nmol/mol. balance gas standards either scrubbed dry real or synthetic air.
Measurement of RNA can be used to study and monitor a range infectious non-communicable diseases, with profiling multiple gene expression mRNA transcripts being increasingly applied cancer stratification prognosis. An international comparison (Consultative Committee for Amount Substance (CCQM)-P103.1) was performed in order evaluate the comparability measurements copy number ratio targets between two samples. Six exogenous synthetic comprising External Control Consortium (ERCC) standards...
Main text The CCQM-K10.2018 comparison aimed to evaluate the capabilities of national metrology institutes (NMIs) prepare and/or value assign primary reference mixtures containing benzene, toluene, ethylbenzene, p-xylene, m-xylene and o-xylene (subsequently referred as BTEX) in nitrogen. This key was separated into two parallel studies. first study, deemed "gravimetric study", evaluated level compatibility BTEX standards provided by NMIs. Seven participating laboratories each submitted one...
Gravimetry is used as the primary method for preparation of standard gas mixtures in most national metrology institutes, and it requires combined abilities purity assessment, weighing technique analytical skills. At CCQM GAWG meeting October 2005, was agreed that KRISS should coordinate a key comparison, CCQM-K53, on gravimetric gas, at level 100 ?mol/mol oxygen nitrogen. compared value each cylinder with an instrument. A mixture particular care to be accurate, because major component...
Key comparison CCQM-K86 was performed to demonstrate and document the capacity of interested national metrology institutes (NMIs) designated (DIs) in determination relative quantity two specific genomic DNA fragments present a biological tissue. The study provides support for following measurement claim: "Quantification ratio number copies specified intact sequence length range 70 100 nucleotides single extract from ground maize seed materials".
The CCQM-K90 comparison is designed to evaluate the level of comparability national metrology institutes (NMI) or designated (DI) measurement capabilities for formaldehyde in nitrogen at a nominal mole fraction 2 μmol mol −1 . was organised by BIPM using suite gas mixtures prepared producer specialty calibration gases. assigned with primary generated dynamically permeation coupled continuous weighing magnetic suspension balance. developed two dynamic sources that provide independent values...
We report a pilot study organized within the Consultative Committee for Amount of Substance (CCQM), in which ozone reference standards 23 institutes have been compared to one common reference, BIPM standard, series bilateral comparisons carried out between July 2003 and February 2005. The BIPM, maintains as its standard photometer (SRP) developed by National Institute Standards Technology (NIST, United States), served laboratory. A total 25 instruments were either directly (16 comparisons)...
Ammonia is an important compound in the chemical industry. It widely used and basis for producing other compounds containing nitrogen. also very hazardous, consequently emissions of ammonia need be controlled monitored. In past years, several national metrology institutes have developed facilities preparation Primary Standard gas Mixtures (PSMs), dynamically generated mixtures comparing certifying ammonia.
Nitrous oxide (N2O) is one of six greenhouse gases that are regulated by the Kyoto Protocol and has a Global Warming Potential (GWP) 296 times carbon dioxide. levels nitrous have increased at rate 0.25%/yr (0.8 ppb/yr) during last ten years. In order to monitor in atmosphere, it necessary use measurement standards with demonstrated equivalence highest level accuracy.
Dimethyl sulfide (DMS) is an important compound in monitoring climate change and monitored by the World Meteorological Organization Global Atmospheric Watch Volatile Organic Compounds (WMO-GAW VOC) program at several sites. It essential that measurement results are accurate consistent among assigned values for primary gas mixtures to meet WMO requirement. The purpose of this comparison compare capability DMS approximately 10 μmol/mol expectation contribute establishment traceability single...

This report presents the results of CCQM-K93, a key comparison between 13 National Measurement Institutes (NMIs), which tested capability NMIs to prepare standard gas mixtures ethanol at nominal amount fraction 120 µmol/mol in nitrogen. composition is typical levels used calibrate evidential breath analysers many countries. Such standards fulfill agreed requirements International Organization Legal Metrology (OIML) for calibration breath-alcohol analysers.
There is a high international priority attached to activities which reduce NOx in the atmosphere. The current level of permitted emissions typically between 50 µmol/mol and 100 µmol/mol, but lower values are expected future. Currently, ambient air quality monitoring regulations also require measurement mole fractions as low 0.2 µmol/mol. production accurate standards at these levels requires either dilution stable higher concentration gas standard or by dynamic technique, for example one...
This key comparison aims to assess the core capabilities of participants in gas analysis. Such competences include, among others, prepare primary standard Mixtures (PSMs), perform necessary purity analysis on materials used mixture preparation, verification composition newly prepared PSMs against existing ones, and capability calibrating a mixture.
