Securing trust in the quality of results of chemical methods examination

Abstract

Securing trust in the quality of examination results is one of the most important segments of the quality management system. Quality management is the first step in ensuring the quality of analytical procedures and predicts the application of appropriate techniques and procedures in order to fulfill the defined quality requirements with an aim to prevent errors in working process. Activities related to quality management include measures that provide statistical control of accuracy of the examined procedure. These activities describe measures that are used to achieve repeatable and reliable examined results. In order to achieve the maximum reliability of the examined results, the validity of the conducted examination is controlled from entering the sample in the laboratory until the release of reports of examination, by continuously monitoring and following all the activities of the analytical process, as well as complete documentation of the quality management system. By continuously monitoring the quality of examination results and with continuous improvement of its' own work procedures through finding mistakes, analyzing the causes of nonconformity, taking preventive and corrective measures, developing its' own procedures of internal control methods, participating in laboratory comparisons and education of staff, the laboratory provides trust in the quality of examination results, and therefore its' own competence.

Obezbeđenje poverenja u kvalitet rezultata ispitivanja jedan je od najvažnijih segmenata sistema menadžmenta kvalitetom. Upravljanje kvalitetom predstavlja prvi stepen obezbeđenja kvaliteta analitičkih postupaka i predviđa primenu odgovarajućih tehnika i postupaka radi ispunjavanja postavljenih zahteva za kvalitetom sa ciljem sprečavanja nastanka greške/neusaglašenosti u radu. Aktivnosti vezane za upravljanje kvalitetom sadrže mere kojima se postiže statistički nadzor tačnosti ispitivanog postupka, odnosno opisuju mere koje se primenjuju za postizanje ponovljivih i pouzdanih rezultata ispitivanja. U cilju postizanja maksimalne pouzdanosti rezultata ispitivanja, valjanost obavljenih ispitivanja kontroliše se od ulaska uzorka u laboratoriju do samog izdavanja izveštaja o ispitivanju, tako što se kontinualno nadgledaju i prate sve aktivnosti analitičkog procesa, kao i kompletna dokumentacija sistema menadžmenta kvalitetom. Kontinuiranim praćenjem kvaliteta rezultata ispitivanja i stalnim unapređenjem sopstvenih postupaka rada kroz pronalaženje grešaka/neusaglašenosti, analiziranje uzroka neusaglašenosti, preduzimanja preventivnih i korektivnih mera, razvoj sopstvenih postupaka interne kontrole metoda, učestvovanje u međulaboratorijskim poređenjima, edukaciju osoblja, laboratorija obezbeđuje poverenje u kvalitet rezultata ispitivanja, a samim tim i svoju kompetentnost.
