The paper presents some recent results of the Radionuclide Metrology Laboratory (RML) from IFIN-HH, in the assurance of quality in radioactivity measurements for nuclear medicine. Three aspects are treated: (i) Participation of the RML in the frame of the IAEA Coordinated Research Program (CRP), E 2.10.05; (ii) Improvement of the secondary standard, based on a CENTRONIC IG12/20A ionization cham...

The aim of this guidance document is to facilitate harmonised flexible scope accreditation within Europe, according to ISO/IEC17025:2005 related to quantitative testing of genetically modified organisms (GMOs) by quantitative real-time polymerase chainreaction (qPCR) for GM events authorised in the EU or which are in the authorisation process.This document gives guidance to and is i...

As a laboratory certified to ISO 9001:2000 and accredited to ISO 17025, rtech laboratories has incorporated an overall system for technical and quality management, which results in benefits observed in daily laboratory practices. Technical requirements were updated to include the addition of formal personnel training plans and detailed records, method development and validation procedures, meas...

As a result of rapid industrialization several chemical forms of organic and inorganic mercury are constantly introduced to the environment and affect humans and animals directly. All forms of mercury have toxic effects; therefore accurate measurement of mercury is of prime importance especially in suspended particulate matter (SPM) collected through high volume sampler (HVS). In the quantifica...

Accreditation to ISO/IEC 17025 is required for EC official food control and veterinary laboratories by Regulation (EC) No. 882/2004. Measurements in hospital laboratories and clinics are increasingly accredited to ISO/IEC 15189. Both of these management standards arose from command and control military standards for factory inspection during World War II. They rely on auditing of compliance and...

Three strains of Rhodobacter sphaeroides of diverse origin have been under investigation in our laboratory for their genome complexities, including the presence of multiple chromosomes and the distribution of essential genes within their genomes. The genome of R. sphaeroides 2.4.1 has been completely sequenced and fully annotated, and now two additional strains (ATCC 17019 and ATCC 17025) of R....

L'équation de Horwitz est l'un des premiers paramètres empiriques à un usage en tant que valeur de référence pour les activités de laboratoires de contrôle qualité et des programmes d'essais d'aptitude. Ce document résume le concept de l'équation de Horwitz, des analyses de ses propriétés; propose d'utiliser l'équation dans des laboratoires qui se conforment à la norme ISO / CEI 17025, et consi...
