Problems of correct validation of the suitability and assessment of the economic efficiency of HPLC methods The article formulates a set of characteristics of the HPLC method required for a complete description of its custom properties. The standard accepted validation procedure has been shown to affect only three of the ten key quality characteristics of an HPLC method. The quality characteristics of the HPLC method that are not included in the standard validation kit are discussed. The classification of the characteristics of the quality of the HPLC method is given, it is proposed to divide them into three groups according to the influence on the suitability and economic efficiency.
High temperature high performance liquid chromatography. Short review The features of high-temperature high-performance liquid chromatography (HT HPLC) are discussed. HPLC methods that use high temperatures, as well as detectors and sorbents used at high temperatures are listed. The areas of application are considered and the main advantages of HT HPLC are shown: a significant reduction in the separation time, an increase in the efficiency of columns, the possibility of using pure water as an eluent. The negative effect of high temperatures on the stability of both the compounds to be separated and the sorbents was noted.
Features of the new edition of the international standard on terms and definitions in the field of conformity assessment ISO / IEC 17000: 2020 In June 2020, the ISO Committee on Conformity Assessment (CASCO), in cooperation with the International Electrotechnical Commission (IEC), completed the updating of the international standard ISO / IEC 17000: 2020 Conformity Assessment. Vocabulary and general principles. The published standard contains terms and definitions in the field of conformity assessment, including the accreditation of conformity assessment bodies. The article contains new terms, their interpretation, examples of application. The concept of the concept of a conformity assessment system, which has undergone changes within the framework of the functional approach, is explained.
