Polarimeters for Processing Applications
The Propol process polarimeter is ideal for process
applications on chiral compounds such as sugars and
pharmaceuticals. It is designed to be placed inline or in
bypass allowing continuous measurements.
Detection of optical rotation in process applications
Good to know
Determination of optical rotation in online and inline processes is essential
for concentration measurements on carbohydrates, amino acids, vitamins,
fragrances and many other chiral compounds. However, conventional
polarimeters cannot be used in process applications as their design does
not allow the instrument’s connection to inline and online processes.
Anton Paar's process polarimeter Propol is designed to meet the special
needs in processing applications. It can be placed just around the process
tube, which makes the Propol an ideal instrument for continuous
monitoring of chiral compounds.
The Propol process polarimeter works
according to the principle of
magneto-optic compensation, making
it a robust instrument for process
measurements.
Propol operates according to the principle of magneto-optic compensation
and does not require any moving parts. It is nearly maintenance-free, a
feature that is unique to Anton Paar’s Propol process polarimeter.
Other Anton Paar instruments
relevant for the application
Anton Paar offers a broad range of
inline and online instruments to
determine density, viscosity and other
parameters.
Propol for inline and online detection of optical rotation
Propol’s measuring range of ±6.000° with an accuracy of 0.001° allows a
concentration measurement as accurate as 0.001 %. The LED light source
has a life time of 100,000 hours, which is equal to more than 11 years of
continuous measurement. To ensure precise determination of optical
rotation, the sample’s temperature is determined with an accuracy of
±0.1 °C, allowing temperature correction of optical rotation when
temperature coefficients are known. To meet the highest safety
regulations, Propol can also be equipped with a closed-air pressured
enclosure system to meet ATEX requirements.
Depending on the chosen sample cell, Propol may only require microliter
amounts of sample. All those features make Propol a valuable instrument
for analysis of chiral compounds in inline and online process applications.
