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
and RF value to that obtained from Standard solution A. Standard solution B
shows four clearly discernible spots.Identification C
A red color develops
It appeared red color.
