● Standard preparation:
Weigh accurately about 5 mg of Pure L-Theanine Powder Working Standard (W1) in 25ml volumetric flask, dissolve and make up the volume with methanol.
● Sample preparation:
Weigh accurately 5mg(W2) of test Pure L-Theanine Powder sample and Transfer the sample to previously dried 25ml volumetric flask, add methanol to dissolve then make up the volume with methanol.
● Procedure:
Separately inject equal volume (20µl) of the standard preparation and the test preparation into chromatogram in the triplicate and note down the area counts of L-Theanine peak calculate the percentage of L-Theanine.
● Calculation:
At and As are the counts of Pure L-Theanine Powder peak in the chromatograms of the test preparation and standard preparation respectively. Ps is the contents of L-Theanine in standard.
