QA/QC

The Marine Institute is accredited to ISO 17025 for toxic marine phytoplankton abundance and composition since 2005 and recognises that regular quality control assessments are crucial to ensure a high quality output of phytoplankton data. We are programmed to apply for the accreditation of this Proficiency Testing scheme under ISO 17043 to INAB (Irish national Accreditation Body) for 2019. All our work is carried out following and to the technical and managerial standard requirements for PT schemes (ISO17043) and the data is statistically analysed using the statistical methods as laid out in ISO13528 ‘Statistical methods for use in PT by interlaboratory comparisons’. We use the statistical database software ProLab Plus from QuoData to do the statistical evaluation of the participants’ data.
