Answer / venkat
Main Reasons to use sucrose solutions :
1. Very Easily prepared
2. Has a fixed rotation value which can calibrated with 10%,
20% and 30% sugar value, and remains constant for those
concentration for a little time only, upto that we can have
a very sharp reading calibration of pure sugar.
3. Mainly polarimeter is used sucrose quality detection for
calibration with pure sucrose is the best deal.
4. Its shows almost no Muta rotation.
5. And last and final...Its most cheap to figure out and get
the calibration done.

Because in Sucrose solution muta rotation was not present.

Answer / venkat nosch
sucrose had standard readings and did not present muta rotation
sucrose have quality detection limit

Sucrose does not have mutarotation.so sucrose is used for polarimeter calibration.we can not use glucose&Fructose because they are having mutarotation.change in optical rotation is called mutarotation.

Answer / s.giri prasad
1.Sucrose does not have mutarotation
2.It is disaccharide mixture of Glucose and Fructose.
3.It is give exact readings and very cheap.
4.It is primary standard and higly stable

why we prefer kbr for ftir than kcl?
we are performed SOR for a particular product the limit is -6 to -10.We face particular bathes it is not meeting the specification.we performed diffrent instrument diffrent analyst we are getting diffrent diffrent results.solvent is dimethyl sulfoxide what could be the reasion

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
