Test Results

Identification A

The infrared absorption spectrum of the sample is concordant with that of the standard

The inferared absorption spectrum of the sample was concordant with that of the standard

Identification B

The principal spot obtained form the test soultion corresponds in appearance and RF 
value to that obtained from Standard solution A.The test is not valid unless the 
chromatogram obtained with Standard solution B shows four clearly discernible spots
 disregarding any spots at the origin.

The principal spot obtained from the Test solution corresponds in appearance
