Automatic Digital Polarimeter – ToronADP™ 200
Automatic Digital Polarimeter – ToronADP™ 200
Automatic Digital Polarimeter ToronADP™ 200 is a fully automatic, constant-temperature polarimeter for measuring optical rotation and reporting specific rotation, concentration, and sugar degree. Built-in Peltier temperature control supports stable measurements when samples are temperature sensitive. The system is designed for routine testing in chemical and pharmaceutical labs, plus food and sugar-related workflows.
ToronADP™ 200 uses an LED cold light source with a high-precision interference filter to deliver a stable polarimetric wavelength at 589.3 nm. Measurement modes cover optical rotation, specific rotation, concentration, sugar, and custom formula calculations for flexible reporting. A large 10.4-inch touch color display supports method-driven operation with quick navigation for daily work.
Documentation controls support labs that need traceable electronic records. Audit trail, electronic signature, and multi-level permission management are included in the specification. Network printing plus PDF and Excel export support reporting and review workflows across teams.
Automatic Digital Polarimeter – ToronADP™ 200 Applications
- Pharmaceutical QC and research: Optical rotation testing supports identity checks for chiral substances and helps track batch-to-batch consistency. Specific rotation calculations help labs compare results under defined tube length, wavelength, and temperature conditions. Documentation features support controlled reporting when required by internal QA procedures.
- Chemical manufacturing and academic labs: Polarimetry supports concentration checks, method development, and verification of optically active intermediates. Multiple measurement modes and custom formulas help standardize calculations across different product lines. Continuous and multiple measurement functions help evaluate stability during a measurement window.
- Food, spices, and dyes: Many organic crystalline substances and extracts show optical activity that can be tracked for quality trends. Stable wavelength control and temperature control help reduce variability during routine checks. Network printing and data retrieval support review when multiple batches are tested daily.
- Sugar analysis: Sugar degree measurement supports routine monitoring using polarimetric scales expressed in °Z. The instrument’s sugar mode and controlled temperature range help keep results consistent during production and QC testing. Industry methods commonly reference ICUMSA guidance for sugar polarimetry.
Standards
- FDA 21 CFR Part 11 when electronic records and electronic signatures are used under regulated record requirements.

Theory and Method
Optically active compounds rotate the plane of polarized light, producing an observed rotation angle (α). The reported value depends on wavelength, temperature, tube length, and sample concentration, so controlled conditions improve comparability. Pharmacopeial methods describe how to measure optical rotation and calculate specific rotation for consistent reporting.
ToronADP™ 200 uses a 589.3 nm light source and supports single, multiple, and continuous measurement modes. Peltier temperature control stabilizes the sample environment across a defined range to reduce drift. Real-time monitoring functions support optical rotation timing and real-time spectrum-style observation during measurement.
