Differences between Analytical Methods
The following charts show the average relative differences between lead conductance value “LCV”
(EBC 7.5), spectrophotometric method, “Spectro” (ASBC 6A) and high performance liquid chromatography
“HPLC” (EBC 7.7 and ASBC 14). The latter is represented as reference value by the blue line.
The green (LCV) and the orange bars (Spectro) show the relative difference compared to HPLC. The
varieties chosen are typical examples from the German growing region Hallertau. The analyses were
carried out within few weeks of harvest and we calculated the average of the last five crop years...
