Sartorius MA100 Halogen/Infrared Moisture Analyzer

Overview

The Sartorius MA100 Halogen/Infrared Moisture Analyzer is a precision thermogravimetric instrument engineered for rapid, reproducible moisture content determination across R&D, QC, and production environments. It operates on the principle of loss-on-drying (LOD): a precisely weighed sample is heated under controlled thermal conditions, and the mass loss—attributable to volatiles, primarily water—is measured in real time using an integrated high-resolution analytical balance (0.1 mg readability). Unlike conventional infrared analyzers relying solely on broad-spectrum IR emitters, the MA100 employs interchangeable heating modules—including halogen lamp, ceramic IR, and quartz heater variants—enabling method-specific optimization for diverse matrix types (e.g., polymers, pharmaceuticals, food powders, or heat-sensitive botanicals). Its monolithic motor-driven heating unit integrates seamlessly with the sample chamber, eliminating thermal lag and cross-contamination risks associated with modular designs. Certified to EC Type Approval standards and supplied with factory calibration documentation, the MA100 meets foundational metrological requirements for regulated laboratories.

Key Features

• High-precision dual-function system: Combines 0.1 mg analytical weighing capability with programmable thermal control (30–200 °C, 1 °C increments)
• SPRM (Smart Parameter Recognition Mode): Automatically derives optimal drying parameters—including temperature ramp profile, hold duration, and endpoint criteria—by referencing user-defined reference methods (e.g., Karl Fischer titration or oven-drying per ASTM E1868)
• Modular heating architecture: Selectable halogen lamp (fast surface heating), ceramic IR (uniform radiant energy), or quartz heater (hybrid response combining speed and homogeneity)
• Plug & Dry™ removable heating unit: Enables full access to the sample chamber for residue removal without tools or disassembly—critical for viscous, oily, or particulate-laden samples
• GLP-compliant operation: Built-in reproTEST function performs automated self-calibration and diagnostic checks per DIN 53149 and ISO 8573-3; supports traceable calibration records with internal weight verification
• Intuitive user interface: Text-based menu navigation, alphanumeric input, 9999-value statistical logging, and customizable display modes (% moisture, dry matter, evaporated mass, etc.)

Sample Compatibility & Compliance

The MA100 accommodates solid, semi-solid, and granular samples up to 100 g on its 90 mm diameter stainless-steel pan. Its adaptive thermal profiles ensure reliable results for hygroscopic materials (e.g., excipients), low-moisture solids (<0.05%), and high-water-content matrices (up to 100%). Method validation is supported through 30 programmable drying protocols, each storing temperature setpoints, timing logic, and termination criteria. The instrument complies with ISO 8573-3 (compressed air moisture testing), DIN 53149 (plastics moisture analysis), and aligns with USP , EP 2.2.32, and ASTM D4457 for comparative LOD validation. When paired with Sartorius LabX software, it satisfies FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and role-based access control—for GMP-regulated environments.

Software & Data Management

Data export is enabled via RS-232 serial interface (RS-485 optional); direct integration with LabX software permits centralized method management, real-time data visualization, statistical reporting (mean, SD, RSD, trend charts), and automated PDF certificate generation. All measurements include timestamp, operator ID, environmental conditions (if external sensor connected), and full parameter audit logs. The built-in printer option provides immediate hardcopy output compliant with ISO/GLP documentation standards—eliminating post-processing delays and reducing transcription errors. User-defined calculation formulas (e.g., moisture × correction factor) are stored per method, ensuring consistency across shifts and analysts.

Applications

• Pharmaceutical manufacturing: Quantification of residual solvents and hydrate water in APIs and finished dosage forms per ICH Q5C guidelines
• Food quality assurance: Rapid moisture monitoring in flour, dairy powders, spices, and pet food to verify shelf-life stability and compliance with Codex Alimentarius limits
• Chemical & polymer labs: Determination of water content in catalysts, resins, and monomers where trace moisture impacts reaction kinetics
• Academic research: Method development for novel biomaterials, nanocomposites, and lyophilized formulations requiring sub-0.1% moisture resolution
• Materials science: Evaluation of desiccant performance, coating uniformity, and hygroscopic swelling behavior in composites

FAQ

What regulatory standards does the MA100 support for audit readiness?

It provides built-in reproTEST diagnostics, EC Type Approval certification, and GLP-aligned documentation features. With LabX software, it achieves full 21 CFR Part 11 compliance.
Can the MA100 replace Karl Fischer titration for all moisture applications?

It serves as a validated alternative for routine LOD testing where volatiles are predominantly water; however, KF remains required for speciation (e.g., distinguishing water from alcohols) or ultra-trace quantification (<10 ppm).
How does SPRM improve method development efficiency?

SPRM reduces manual trial-and-error by automatically generating repeatable drying protocols based on reference method outcomes—cutting method validation time by up to 70% in typical QC workflows.
Is the halogen heating module suitable for temperature-sensitive samples?

Yes—halogen lamps offer rapid thermal response with precise power modulation; combined with real-time mass feedback, they enable gentle, endpoint-controlled drying without charring or decomposition.
Does the MA100 require external calibration weights during routine use?

No—the integrated reproTEST function uses the internal calibration weight to verify linearity and repeatability before each measurement sequence, satisfying ISO 9001 and ISO/IEC 17025 internal verification requirements.
