INTERLABORATORY PROGRAMS: USE FOR PRECISION CONTROL OF ANALYTICAL METHOD

Considering the amount of possible errors in laboratory analyses impacting on credibility, reliability and the excess expenditure on reproducibility and errors and time in the execution of tasks, interlaboratory programs have been part of a corrective measure most used in recent years. They are quality qualification programs that contain a series of measurements of one or more properties, performed independently, by a group of laboratories, compared with known values in samples of a given material in order to check the reliability of all. These programs use the internal calibrations and controls of several laboratories in proposed tests and with known values in a comparative, as a validator of efficiency and reliability. These programs guarantee the quality of results and are used as a diagnosis of sources of errors in order to correct them. In this research, I present such methodology and it is confirmed that these have been sources of reliability, methodology of error discovery and projection of mitigatory measures as well as savings in human and material resources.
