IR120 Professional Infrared Moisture Analyzer

Overview

The IR120 Professional Infrared Moisture Analyzer is a high-precision, thermogravimetric moisture determination system engineered for laboratories requiring trace-level moisture quantification in solid and semi-solid samples. Utilizing calibrated infrared heating combined with monolithic electromagnetic force compensation (EMFC) weighing technology, the IR120 measures moisture loss in real time by continuously monitoring mass change during controlled thermal drying. Its operational principle complies with ASTM D4017, ISO 12358, and USP <921> guidelines for loss-on-drying (LOD) methodology. Designed for routine QC/QA environments—including pharmaceutical manufacturing, food safety testing, polymer quality control, and battery material characterization—the instrument delivers repeatability of ±0.001% moisture content and weighing resolution down to 0.1 mg under GLP-compliant conditions.

Key Features

• Monolithic EMFC weighing system with internal automatic calibration via built-in reference weights—ensures long-term stability and eliminates manual recalibration drift.
• Hybrid infrared heating architecture: tungsten–halogen filament emitter paired with fused quartz reflector plate—achieves rapid, uniform thermal distribution across the sample surface while maintaining heater lifetime exceeding 15 years.
• Programmable drying profiles: up to 30 user-defined methods stored onboard, supporting stepwise temperature ramps, fixed-temperature holds, and auto-termination based on mass-change rate thresholds (e.g., ≤0.1 mg/min over 60 s).
• Modular heating unit design: slide-out heating assembly enables full access to the sample chamber—facilitating rapid decontamination after spillage or residue buildup without tools or service intervention.
• Integrated thermal printer as standard equipment: generates audit-ready reports including date/time stamp, method ID, initial/final mass, moisture %, dry residue %, and operator ID—formatted for traceability in regulated environments.
• Three-year comprehensive warranty covering electronics, optics, weighing mechanism, and heating subsystems—reflecting structural robustness and component-level reliability validation per IEC 61000-4 EMC standards.

Sample Compatibility & Compliance

The IR120 accommodates samples ranging from 0.1 g to 100 g (depending on required precision), including hygroscopic powders (e.g., excipients, catalysts), granules (pharmaceutical tablets, feed pellets), pastes (electrode slurries, adhesives), and thin films (lithium-ion separator coatings). It supports compliance with FDA 21 CFR Part 11 requirements when paired with optional software-enabled electronic signature and audit trail modules. All hardware components meet RoHS Directive 2011/65/EU and CE marking criteria for laboratory instrumentation. Method validation documentation—including precision, accuracy, linearity, and ruggedness data—is available upon request to support IQ/OQ/PQ protocols.

Software & Data Management

While the IR120 operates autonomously via its intuitive front-panel interface, optional PC connectivity (RS-232 or USB) enables bidirectional data exchange with LIMS or ELN platforms. The companion software package provides raw mass-vs.-time curve visualization, comparative analysis across batches, statistical reporting (mean, SD, RSD), and export to CSV or PDF formats. All measurement sessions are timestamped and logged with immutable metadata—including environmental temperature/humidity readings (when external sensors are connected)—to satisfy GLP/GMP data integrity requirements. Audit trails record every parameter modification, user login, calibration event, and report generation.

Applications

• Pharmaceutical: Quantification of residual solvents and hydrate water in APIs and final dosage forms per ICH Q5C and USP <921>.
• Food & Agriculture: Moisture profiling in cereals, dairy powders, spices, and pet food to ensure shelf-life stability and regulatory labeling accuracy.
• Chemicals & Polymers: Monitoring moisture ingress in polyamide, PEEK, and epoxy resins prior to extrusion or molding—critical for preventing hydrolytic degradation.
• Battery Materials: Precise LOD assessment of cathode/anode active materials and electrolyte additives where ppm-level water compromises cell performance and safety.
• Research Labs: Method development for novel drying kinetics studies, including Arrhenius-based activation energy modeling using multi-temperature runs.

FAQ

Does the IR120 require external calibration weights for daily verification?

No—the integrated monolithic weighing system performs automatic internal calibration using certified reference masses before each analysis cycle.
Can the IR120 be validated for use in FDA-regulated manufacturing?

Yes—its hardware design, firmware architecture, and optional software modules support full 21 CFR Part 11 compliance when implemented with appropriate procedural controls.
What is the maximum sample temperature achievable during drying?

The heating module is rated for continuous operation up to 200 °C, with programmable setpoints in 1 °C increments across the 50–200 °C range.
Is the printed report compliant with ISO/IEC 17025 documentation requirements?

Yes—the embedded thermal printer outputs fully traceable reports containing all mandatory elements: instrument ID, method parameters, raw data summary, and operator identification.
How often does the quartz reflector plate require cleaning or replacement?

Under normal usage, the fused quartz reflector requires cleaning only if visible residue accumulates; no scheduled replacement is specified—its design lifetime matches the 15-year heater rating.
