Overview
The Drick DRK112B Halogen Moisture Analyzer is a thermogravimetric instrument engineered for rapid, accurate, and repeatable determination of moisture content in solid and semi-solid samples. It operates on the principle of loss-on-drying (LOD), where a halogen lamp provides uniform, controllable heating across the sample surface, while an integrated high-precision analytical balance continuously monitors mass change in real time with sub-milligram resolution. The system calculates moisture content (%) as the percentage of initial mass lost upon drying to a user-defined endpoint—either by time, temperature, or mass stability criteria. Designed for routine quality control and R&D environments, the DRK112B delivers measurement repeatability ≤0.01% RSD for homogeneous samples and supports method development in accordance with ASTM D4457, ISO 15512, and USP <921> guidelines for moisture analysis.
Key Features
- Halogen heating source with adjustable temperature range from 50 °C to 200 °C in 1 °C increments, ensuring precise thermal control and minimal sample oxidation.
- Integrated analytical balance with 0.001 g readability and ≥110 g capacity, calibrated internally with traceable weights and compliant with ISO/IEC 17025 calibration requirements.
- Real-time mass monitoring and dynamic moisture curve visualization via built-in LCD interface—no external PC required for basic operation.
- Pre-programmed and customizable drying methods, including standard, step, rapid, and auto-endpoint modes, supporting GLP-compliant method storage (up to 20 user-defined protocols).
- Rugged aluminum alloy housing with heat-resistant ceramic sample pan holder and ergonomic front-access design for easy cleaning and maintenance.
- RS-232 and USB-B interfaces for data export to LIMS or Excel-compatible formats; optional Ethernet module available for networked lab integration.
Sample Compatibility & Compliance
The DRK112B accommodates diverse sample types—including powders, granules, films, fibers, pastes, and lyophilized solids—with typical sample masses ranging from 0.5 g to 30 g. Its open-chamber geometry allows rapid loading and visual inspection during analysis. The instrument meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and safety standards per IEC 61010-1. Method validation documentation supports compliance with FDA 21 CFR Part 11 when paired with optional audit-trail-enabled software (DRK-MAS v3.2). It is routinely deployed in GMP-regulated environments for raw material release testing in pharmaceuticals, excipient QC in food manufacturing, and polymer moisture specification verification in plastics processing—all aligned with ISO 17025 accredited laboratory practices.
Software & Data Management
DRK-MAS (Moisture Analysis Suite) v3.2 is the optional PC-based software platform that extends the DRK112B’s capabilities beyond standalone operation. It enables full method parameterization, real-time graphing of mass vs. time and derivative curves, statistical reporting (mean, SD, CV%), and automated PDF report generation with embedded digital signatures. All data entries—including operator ID, timestamp, method name, and calibration logs—are stored with immutable audit trails meeting ALCOA+ principles. Data files are saved in encrypted .dms format and can be exported as CSV or XML for integration into enterprise QMS systems. Software validation packages (IQ/OQ/PQ) are available upon request for regulated users.
Applications
- Food industry: moisture quantification in flour, dairy powders, snacks, and pet food to ensure shelf-life stability and regulatory labeling accuracy (e.g., FDA 21 CFR 101.9).
- Pharmaceuticals: residual solvent and water content testing of APIs and tablets per USP <921>, supporting stability-indicating assay development.
- Packaging & paper: moisture profiling of corrugated board, kraft paper, and laminated films to prevent delamination and printing defects.
- Polymers & composites: pre-drying verification of hygroscopic resins (e.g., PA6, PET) prior to extrusion or injection molding.
- Academic research: kinetic modeling of drying behavior using multi-segment temperature ramping and derivative moisture rate analysis.
FAQ
What is the typical drying time for most samples?
Drying duration varies by sample matrix and target endpoint but typically ranges from 3 to 12 minutes under standardized 105 °C protocols.
Does the DRK112B support automatic calibration?
Yes—it features internal calibration with motorized weight deployment and automatic drift compensation at user-scheduled intervals.
Can it be used for volatile organic compound (VOC) loss measurement?
No—the DRK112B is optimized for water and bound moisture; for VOC quantification, dedicated headspace-GC or Karl Fischer titration is recommended.
Is third-party calibration certification available?
Yes—NIST-traceable calibration certificates issued by ISO/IEC 17025-accredited labs are provided as an add-on service.
How is method transfer handled between instruments?
Method parameters and calibration profiles can be exported/imported via USB drive in standardized .mth format, ensuring cross-platform consistency across DRK112B units in multi-site facilities.
