metrology

"We are constantly working on making our automatic calibration modules more accessible to users so that complex calibration procedures could be substituted with easy but metrologically sound automatic calibration." In addition, he said, the company is working on creating application-specific software that will limit users' exposure to just the applications that are relevant to them.

If clinical test results are to be comparable across time, across different instrument platforms, or across labs, they must be metrologically traceable to the same measurement reference.

Metrologically sensitive measurement results need to be traceable and have an accurate timestamp.

Hence, there remains a requirement for routine assays to provide metrologically traceable results.

Therefore, the traceability of the metrologically higher-order reference method was maintained across different platforms using the Abbott clinical chemistry assays.

We propose an approach for determining a combined result which is metrologically compatible with the contributing results.

Also defined in AOAC Official method 892.35 and with ISO Guide 30, a CRM is characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty and a statement of metrological trace ability.

The accuracy error of the nanometric mechatornic systems in the endowments of the laboratory was determined metrologically in the following value matrix: Maximum error Maximum uncertainty 50 nm [+ or -] 25 nm 1800nin [+ or -] 1000 nin Medium radio Maximum uncertainty 12,5 mm [+ or -] 25 nm 0,492 in [+ or -] 1000 nin

The traceability to ITS-90 of the thermocouples to be calibrated is often possible only by time-consuming and metrologically complex comparison measurements against radiation thermometers in furnaces, specially developed for this purpose.
