POLARIMETERS
AP-81
Introduction:
The polarimeters is a kind of instrument for
measuring the optical rotation of a substance. Through
measuring the optical rotation, the polarimeters can be
used to analyze the concentration, content, and purity of a
substance. The PLRA
—
2B automatic polarimeters utilizes the
photoelectric detection automatic balance principle and
the results are displayed by LCD. PLRA
—
2B automatic
polarimeters is characterized by its small size, high sensitivity,
human error-free, easy reading, and so on.
Furthermore, this instrument is also suitable to the sample of
low optical rotation which is difficult to be analyzed by
visual polarimeters. Therefore, it can widely be used in
various fields of the organic chemical industry.
Agriculture: use in contents analyses of agricultural
antibiotic, hormone, microbial agro-pharmaceuticals and
agricultural products.
Medication: use in analyses of antibiotic, vitamin and
glucose and in pharmacological research.
Food: use in analyses of sugar, monosodium glutamate and
soy sauce, in inspection of their final products and
determination of sugar content in food.
Petroleum: use in analyses of mineral oil and in control of oil
ferment process.
Essence: use in analyses of essential oil.
Health: use in analyses of diabetics’ urine.
