(c)  Use the gradient conditions described below.

(d)  Use an inlet temperature of 250°.

(e)  Use a flame ionisation detector at a temperature of 250°.

(f)  Inject 1 µl of each solution.

When the chromatograms are recorded under the prescribed conditions the retention times are: levomenthol, about 2.1 minutes; camphor, about 2 minutes. 

determination of content
