Sartorius MA160-1CN Infrared Moisture Analyzer

Overview

The Sartorius MA160-1CN Infrared Moisture Analyzer is a precision thermal gravimetric instrument engineered for rapid, reproducible determination of moisture content in solids, semi-solids, and viscous samples. It operates on the principle of infrared halogen heating combined with high-resolution mass monitoring—measuring real-time mass loss during controlled thermal drying. Unlike traditional oven-drying methods requiring hours, the MA160-1CN delivers validated results in minutes while maintaining traceable compliance with international standard test protocols including ISO 1183, ASTM D4442, and USP <921>. Its design targets laboratories where throughput, inter-operator consistency, and audit-ready documentation are critical—particularly in pharmaceutical quality control, food safety testing, polymer manufacturing, and chemical raw material release.

Key Features

• Infrared Halogen Heating System: Provides uniform, adjustable radiant heat (up to 200 °C) with fast thermal response and minimal overshoot—ensuring consistent drying kinetics across heterogeneous samples.
• High-Precision Dual-Range Analytical Balance: Integrated 0.1 mg readability balance with automatic internal calibration and drift compensation, optimized for dynamic mass tracking during rapid dehydration events.
• Guided Method Development Workflow: A three-step, context-aware interface assists users in defining drying temperature, ramp profiles, endpoint criteria (e.g., mass change threshold or time-based termination), and validation parameters—reducing method development time to under 45 minutes.
• Ergonomic Sample Handling Architecture: Includes a snap-fit sample pan guard, magnetic sample holder, and tool-free pan alignment—minimizing handling variability and reducing operator-induced error.
• Visual Progress Monitoring: Multi-color status LED ring provides at-a-glance indication of current analysis phase (preheat, drying, cooling, stabilization, result display), visible up to 10 meters in ambient lab lighting.
• Maintenance-Optimized Construction: The heating module and chamber base plate are fully removable and certified dishwasher-safe (IEC 60335-1), eliminating residue buildup and supporting routine cleaning validation per laboratory SOPs.

Sample Compatibility & Compliance

The MA160-1CN accommodates a broad range of sample types—including powders (e.g., APIs, excipients), granules, pellets, pastes, gels, and hygroscopic films—without requiring pre-grinding or dilution in most cases. Its open-chamber geometry allows direct placement of irregular or oversized specimens (max. Ø 90 mm × H 40 mm). All firmware and embedded logic comply with ISO/IEC 17025 requirements for measurement uncertainty estimation. When paired with Sartorius LabX software (optional), the system supports full 21 CFR Part 11 compliance—including electronic signatures, audit trails, role-based access control, and immutable result archiving. Routine performance verification is enabled via ReproEasy reference pads, which provide NIST-traceable mass-loss profiles for daily system suitability checks.

Software & Data Management

While the MA160-1CN operates as a standalone instrument with intuitive front-panel navigation, it is fully compatible with Sartorius LabX™ PC-based software for centralized method deployment, remote monitoring, and regulatory reporting. LabX enables method synchronization across multiple MA-series analyzers, automated report generation (PDF/CSV), integration with LIMS via ODBC or REST API, and configurable electronic signature workflows. All method files—including heating profiles, endpoint logic, and metadata—are stored in encrypted binary format with SHA-256 checksums to ensure integrity. Internal memory retains up to 100 methods and 1,000 result records with timestamps, operator IDs, and environmental logs (ambient temperature/humidity if external sensors are connected).

Applications

This analyzer is routinely deployed in regulated environments for: moisture content verification of active pharmaceutical ingredients (APIs) prior to lyophilization; residual solvent quantification in polymer resins; water activity correlation studies in cereal-based food matrices; moisture stability testing of desiccant packaging materials; and QC release testing of catalysts and metal oxides in fine chemical synthesis. Its repeatability (RSD ≤ 0.2% for homogeneous samples ≥1 g) and linearity across 0.01–100% w/w moisture ranges make it suitable for both routine batch testing and method transfer between R&D and production labs.

FAQ

What standards does the MA160-1CN comply with for moisture analysis?
It supports method development aligned with ISO 1183-1, ASTM D4442, AOAC 952.08, and USP <921>, with hardware-level traceability to national metrology institutes via factory calibration certificates.
Can I transfer methods between different MA-series instruments?
Yes—method files are interoperable across MA150, MA160, and MA250 models, enabling seamless scaling from R&D to high-throughput QC without revalidation.
Is the instrument suitable for GLP or GMP audits?
When operated with LabX software and configured with appropriate user roles and audit trail settings, it meets core GLP and GMP data integrity requirements per FDA and EMA guidance documents.
How often should performance verification be performed?
Daily verification using ReproEasy reference pads is recommended before first use and after any maintenance event; full calibration is required annually or per internal SOP.
Does the MA160-1CN support network connectivity?
It features USB host/device ports and optional Ethernet connectivity (via LabX), enabling integration into enterprise networks for centralized data aggregation and remote diagnostics.
