By combining these techniques, researchers can determine the botanical and geographical origin of wine samples, providing a robust tool for authenticity testing in line with Regulation (EU) 1308/2013. Standard methods for SNIF-NMR and IRMS analysis, as outlined in OIV-MA-AS311-05 and OIV-MA-AS312-06, involve distillation of samples, followed by additional sample preparation steps ...
What to Expect at GAS Analysis 2026 Gas metrology, traceability, and uncertainty: technical sessions focused on reference methods, measurement assurance, and best practice for accurate, defensible gas quantification. ...
The term “buttweld” refers to the method of connection; the ends of the elbow are beveled to be welded directly onto the ends of the pipes. ...
It’s a reference material used as a standard to calibrate and validate laboratory tests. ...
The systems, which have been used for decades in places like college campuses, work best in regions with diverse energy loads, like neighborhoods adjacent to industrial parks. Networked geothermal refers to a method of heating and cooling buildings and homes by using a ground-source heat pump to transfer liquid via a looped pipe system. ...
EU law mandates determining milk fat purity with ISO 17678/IDF 202, a standardised method based on gas chromatographic analysis of triglycerides and cholesterol. Though a standard method exists for milk fat purity testing, reliable results depend on laboratory proficiency. It is widely accepted that laboratories need to demonstrate their proficiency in the ...
It is the standard setting committee for future reference methods for gas measurement in all major applications. One of the key topics was the monitoring of Nitrogen based air pollutants and the product of nitrogen based industrial gases. ...
Whether you use thermodynamic principles or the pharmacopeia method—a widely accepted reference method—it is important to comprehend the melting point process's theoretical and practical applications. ...

In collaboration with the scientists from the IFCC working group on the standardisation of HbA2, the JRC has developed two new reference materials: ERM®-DA485/IFCC and ERM®-DA486/IFCC. These CRMs are blood haemolysate materials certified for the amount-of-substance fraction of HbA2 versus total haemoglobin, produced within the scope of ISO 17034 accreditation. Homogeneity ...
The flexibility of sputter-sectioning, in combination with the principal advantages of SIMS technique, such as large dynamic range both in the mass separation and detection systems, enables the SIMS technique to be extremely sensitive for the quantitative analysis of solid surfaces and thin films. With optimized experimental conditions, like extremely low primary beam current (down to ~ 10 nA) ...
Reference materials ensure useful, reliable and comparable results from different methods and laboratories. ...
Analytical Performance: Results of an evaluation of 152 COVID-19 patient samples tested with the Symphony IL-6 NPT (using whole blood) and the Roche Test (using plasma) showed an excellent correlation between two test methods (r=0.9490)5,6. The authors also report that the analytical precision of the Symphony IL-6 NPT was acceptable, with less than 15% imprecision. ...
Spring Design Attention And Roll Forming MethodThe coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. ...
Over 300 of these subjects were found to be SARS-CoV-2 positive, representing a broad range of viral loads (expressed as the Ct or “cycle threshold” value of the test). miDiagnostics’ Test showed excellent equivalence with the results obtained from the reference method. A powerful tool for pandemic management Since the start of the pandemic, ...
To ensure food safety, official controls for the detection of PAPs were put in place. The European Union Reference Laboratory for Animal Proteins (EURL-AP), hosted by the Centre Wallon de Recherches Agronomiques in Gembloux, Belgium, developed and validated a DNA-based method for the detection of animal proteins of poultry (chicken and turkey) origin and the JRC ...
Cairsens micro-sensors allow to measure specific pollutants with results comparable to reference methods. They are used worldwide by our customers who are looking for new technologies in air quality monitoring. ...

“It is also pleasing to note that standard reference methods are specified for the testing of stoves, and we have been supplying test houses with analysers so that they can check existing burners as well as the latest products, both during and after ...
Titration is an important analytical method that is widely used for pharmaceutical assay testing. However, many USP monographs still refer to manual visual endpoint titration methods. ...
The instrument received US EPA Federal Reference Method (FRM) designation in 2015 and is becoming recognized as the most accurate commercially available method for assessing ambient O3 gas concentrations. “An accurate ozone monitoring method, free of any potential interferences, will enhance the ability of the states to ...
Zeta potential is calculated from the electrophoretic mobility of a material. Currently, two methods are mainly used, namely electrophoretic light scattering (ELS) and acoustophoretics. Despite the widespread use of these methods, no reference materials allowing traceable calibration of acoustophoretic instruments are currently available and ...
