Precisa 365EM Series High-Performance Halogen Moisture Analyzer

Overview

The Precisa 365EM Series High-Performance Halogen Moisture Analyzer is an advanced thermogravimetric instrument engineered for precise, rapid, and repeatable moisture content determination in solid and semi-solid samples. Based on the principle of loss-on-drying (LOD), the system employs a high-intensity halogen lamp as its heating source to uniformly dry samples while continuously monitoring mass loss via an integrated high-resolution analytical balance—specifically the 360EP-grade microbalance platform. This architecture ensures thermal stability, minimal temperature gradient across the sample pan, and high reproducibility across repeated measurements. Designed and manufactured in Switzerland, the analyzer meets stringent metrological requirements for laboratory and quality control environments where regulatory traceability, audit readiness, and operational robustness are critical.

Key Features

• Full cast-aluminum monocoque housing providing mechanical rigidity, electromagnetic interference (EMI) shielding, and effective thermal isolation between weighing and heating modules.
• Backlit graphical LCD display with real-time dynamic plotting of moisture loss curves—enabling immediate visual assessment of drying kinetics and endpoint detection.
• Smart Calibration System (SCS): fully automated internal calibration routine triggered by time, temperature drift, or user command—ensuring long-term accuracy without external weights.
• GxP-ready functionality including built-in real-time clock with timestamped data logging, electronic signature support, and full audit trail capability compliant with FDA 21 CFR Part 11 requirements when used with validated software.
• Multi-tier user management system supporting customizable roles, password-protected access levels, editable sample IDs, and operator-specific authentication—essential for GLP/GMP-regulated workflows.
• Mechanical overload protection and pan-leveling sensors prevent damage during handling and ensure consistent weighing performance under variable environmental conditions.

Sample Compatibility & Compliance

The EM120-HR accommodates a broad range of sample types—including pharmaceutical powders, foodstuffs, polymers, minerals, and agricultural products—with typical sample masses ranging from 0.5 g to 120 g. Its halogen heating system delivers rapid, controllable ramp rates (0.1–20 °C/s) and stable plateau temperatures up to 200 °C, enabling method development per ASTM D4442, ISO 712, USP <921>, and AOAC 952.08. The instrument supports full 3Q validation (Installation Qualification, Operational Qualification, Performance Qualification) documentation packages, including IQ/OQ templates, test protocols, and raw data export formats compatible with LIMS integration. All firmware and embedded software are developed under IEC 62304-compliant processes.

Software & Data Management

Data acquisition and analysis are managed through Precisa’s proprietary firmware environment, which stores all measurement records—including weight vs. time profiles, final moisture %, standard deviation, and statistical summaries—in non-volatile memory. Export options include CSV and XML formats via USB mass storage mode or RS232 serial transmission. Optional Ethernet and Bluetooth connectivity modules enable direct integration into enterprise networks for centralized data archiving, remote diagnostics, and automated report generation. Audit trails record every user action—including method edits, calibration events, and result deletions—with immutable timestamps and operator IDs, satisfying ALCOA+ data integrity principles.

Applications

• Pharmaceutical QC labs performing moisture testing on active pharmaceutical ingredients (APIs), excipients, and finished dosage forms per USP <921>.
• Food manufacturing facilities verifying compliance with moisture specifications for flour, dairy powders, coffee, and pet food to ensure shelf-life stability and microbial safety.
• Chemical and polymer producers monitoring residual solvent content and hygroscopicity in resins, catalysts, and battery electrode materials.
• Academic and contract research laboratories conducting comparative drying kinetics studies or developing custom LOD methods for novel biomaterials.
• Regulatory submission support—raw data files, calibration logs, and validation reports are structured to align with EMA, PMDA, and Health Canada submission guidelines.

FAQ

What standards does the EM120-HR comply with for moisture analysis?
