Overview
The Drick DRK-Z830 is a high-precision, temperature-regulated automatic polarimeter engineered for reproducible optical rotation measurements in pharmaceutical, food & beverage, chemical, and academic quality control laboratories. It operates on the fundamental principle of plane-polarized light interaction with optically active substances—measuring the angular deviation (rotation) induced as monochromatic light passes through chiral samples. The instrument employs a solid-state 589.3 nm LED light source calibrated to match the spectral output of sodium D-line lamps, ensuring metrological consistency with international reference standards (e.g., ISO 5725, USP ). Its integrated Peltier-controlled cell compartment maintains sample temperature within ±0.1 °C across a programmable range of 10–40 °C, eliminating thermal drift—a critical requirement for pharmacopeial assays (e.g., EP 2.2.7, JP 2.06) and regulatory-compliant sugar analysis.
Key Features
- True-color 7-inch capacitive touchscreen interface with intuitive icon-driven navigation and multilingual OS support (English, Spanish, French, Chinese)
- Digital enhanced measurement architecture featuring dual-phase lock-in amplification and real-time noise suppression for stable baseline performance
- Automated zero-point calibration using internal quartz reference plates traceable to NIM (National Institute of Metrology, China)
- Programmable temperature ramping and hold functions with built-in thermistor feedback and auto-compensation for refractive index variation
- Robust stainless-steel optical housing with anti-vibration base mount and dust-resistant sample chamber door
- Compliance-ready design supporting audit trail generation, user-level access control, and electronic signature capability (aligned with FDA 21 CFR Part 11 principles)
Sample Compatibility & Compliance
The DRK-Z830 accommodates standard 100 mm, 200 mm, and custom-length sample cells (including jacketed thermostatic cells), compatible with aqueous solutions, organic solvents (e.g., ethanol, chloroform), syrups, essential oils, and pharmaceutical suspensions. All optical path components are certified free of birefringence and meet ISO 10110-7 surface quality specifications. The system supports full compliance with pharmacopeial methods including United States Pharmacopeia , European Pharmacopoeia 2.2.7, Japanese Pharmacopoeia 2.06, and GB/T 613–2022 (Chinese National Standard for Chemical Reagents). Data integrity protocols include time-stamped measurement logs, operator ID tagging, and immutable result archiving—facilitating GLP and GMP-aligned validation documentation.
Software & Data Management
Equipped with Drick PolarSoft v3.2 firmware, the instrument enables local data storage (≥10,000 records), CSV/Excel export, and optional LAN/Wi-Fi connectivity for LIMS integration. The software provides configurable report templates compliant with ISO/IEC 17025 reporting requirements, including uncertainty estimation per GUM (Guide to the Expression of Uncertainty in Measurement). Audit trail functionality records all parameter changes, calibration events, and user logins with tamper-proof timestamps. Optional 21 CFR Part 11 module delivers role-based permissions, electronic signatures, and encrypted database backup—validated for use in regulated environments subject to FDA, EMA, or NMPA inspection.
Applications
- Pharmaceutical QC: Enantiomeric purity assessment of chiral APIs (e.g., ibuprofen, levodopa), batch release testing per ICH Q5C guidelines
- Fine Chemicals: Concentration determination of optically active intermediates (e.g., menthol, camphor, tartaric acid)
- Food & Beverage: Sucrose content quantification in syrups, honey, soft drinks, and fruit juices per AOAC 951.02 and ICUMSA methods
- Academic Research: Kinetic studies of enzymatic hydrolysis (e.g., invertase activity), polymerization monitoring of chiral monomers
- Biotechnology: Monitoring optical rotation shifts during biocatalytic asymmetric synthesis and fermentation processes
FAQ
What temperature stability does the DRK-Z830 achieve during measurement?
The Peltier-based thermostatic system maintains cell temperature within ±0.1 °C over 30-minute continuous operation at setpoints between 15–35 °C.
Is the LED light source replaceable by the user?
Yes—the 589.3 nm LED module is field-replaceable with factory recalibration certificate provided upon service.
Does the instrument support external PC control via RS232 or USB?
Yes—full SCPI command set is implemented over both RS232 (DB9) and USB Virtual COM port for automated script integration.
How is measurement traceability ensured?
Each unit ships with a NIM-traceable calibration certificate referencing certified quartz control plates (±0.001° accuracy), valid for 12 months under normal operating conditions.
Can the DRK-Z830 be validated for GMP environments?
Yes—IQ/OQ documentation packages, URS templates, and 21 CFR Part 11 configuration files are available upon request for qualified users.
