What is the difference between Optical rotation and Spcefic
optical rotation
Answer Posted / sanjay bute
Optical rotation is the turning of the plane of linearly
polarized light about the direction of motion as the light
travels through certain materials. It means it is only a
measure of degree of polarised light.
But Specific optical rptation is the observed angle of
optical rotation (α) when plane-polarized light is passed
through a sample with a path length of 1 decimeter and a
sample concentration of 1 gram per 1 millilitre
optical rotaion(α)
Specific optical rotation = -------------------
path length in decimeters x C
C = concentration in g/ml
The specific optical rotation is Temperature dependent and
also it depends on wavelength of light used for measurement
Generally the sodium D line is used at 589 nm for
measurement.

My question about gas chromatography sulfur chemiluminsecence detector. I test unknown sample gas by GC-SCD (calibrated ) and the result of *H2S is 279 PPM , *but when I test the same sample with the GC-TCD (calibrated ) the value of *H2S is 2500 PPM . I'd like to inform you that both GCs are calibrated and have very good operation conditions with stable parameters . the question is if the sample gas with higher H2S over detection limits of SCD detector (1000 ppm). why the result it 279 ppm Best regards
