# Commission Regulation (EC) No 2870/2000 of 19 December 2000 laying down Community reference methods for the analysis of spirits drinks, Division 8.4: Linearity test

Extent: E+W+S+N.I.

Prior to the commencement of the analysis the linearity of the response of the FID should be checked by successively analysing in triplicate each of the linearity standard solutions (4.5.3).
From the integrator peak areas or peak heights for each injection plot a graph of their mother solution concentration in g/l versus the ratio R for each.
R trans-anethole peak height or area divided by the estragole peak height or area.
A linear plot should be obtained.
