LPP Precision Data Series
AOCS Technical Services is now offering the results of the four rounds (8 samples) of the Laboratory Proficiency Program (LPP). The results, compiled for each series and test method, are presented by number of analyses, number of outliers mean, standard deviation after outlier removal, relative standard deviation (RSD%), and reproduceability coefficient (R).

The LPP Precision Data Series is a valuable reference tool that can be used for determining the expected variability in the methods used in your laboratory. Using this information, you can compare your method performance data with an international peer group; set product specifications in line with analytical expectations; and compare the performance of your in-house method with a peer group following AOCS recommendations.
