Quality
Ring Test
In order to guarantee the quality of the methods used at the laboratory we participate in the following national and international inter-laboratory ring tests.
The laboratory, following on from its NFTA (National Forage Testing Association, USA) certification, remains in line with the accuracy of the results obtained by over 200 laboratories in the world for DM, CP, NDF, ADF, ADIN and ADL.
In addition, the laboratory follows the EEC Reg. 152 through its participation in the BIPEA ring test (Bureau interprofessionnel des Etudes Analytiques, Paris – FR)
The quality of the results obtained with the NIR and XRF methods are constantly monitored through participation in the Università di S. Cuore ring test (Pc, IT); AAFCO (USA); BIPEA (FR); WEPAL (NL).
The methods we apply to zootechnical food are monitored as follows:
