NMKL Protocol:
NMKL Protocol No. 5, 2011: Analytical Quality Control ] Guidelines for the Publication of Analytical Results of Chemical Analyses in Foodstuffs
Page 4 NMKL Newsletter
These guidelines describe analytical quality control procedures that are intended to help ensure the quality and reliability of published analytical data. They are based on quality criteria such as sampling procedures, method selection and description, use of certified reference materials and participation in proficiency testing.
In addition, they include some advice on how to organize the description of the quality assurance in the manuscript. The quality assurance criteria are summarised in a Check]list, shown to the right.
The protocol is intended for use by all parties involved in the publishing process, i.e. manuscript authors, journal editors and manuscript reviewers/referees. The check list can be of assistance to the persons involved in order to simplify/standardize the reviewing process.
The protocol is elaborated under the leadership of Lars Jorhem, National Food Administration, Sweden, and can be downloaded free of charge under Protocols on NMKL’s homepage. The protocol is available in English.
