Easy Measurement:
The polarimeters with 589.44nm
monochromatic sodium lamp. After powered on, the
polarized light beam is immediately project on filter,
polarizer etc. You can view the visual fields of brightness or
shade through eyepiece. Put the sample tube in
measuring field chamber. Rotate the vernier knob again,
you can view equal brightness. Read the scale from
magnifier that is measured value.
Specific Optical Rotation Measurement:
Specific optical rotation is constant of substance, you can
measure it by 100mm glass tube when temperature of
solution at 20
o
C.
Purity Measurement:
The polarimeters is ideal for
determining purity of sample. If you want to know its
purity, you need only measure its the angle of rotation and
calculate it.
Concentration Measurement
:
For some substance of
known specific optical rotation, you can measure its the
angle of rotation and calculate concentration according
to formula.
International Sugar Scale:
According to international
sugar scale, put the 26 grams pure sugar in solution, The
angle of rotation of solution is 34.626
o
. By the rules, you can
calculate the purity of sugar.
