MA150 Infrared Moisture Analyzer

Overview

The MA150 Infrared Moisture Analyzer is a precision laboratory instrument engineered for rapid, reliable, and traceable moisture content determination in solid and semi-solid samples using the loss-on-drying (LOD) principle. It employs a high-efficiency ceramic infrared heating source to induce controlled thermal dehydration, while a monolithic super dual-lever single-body load cell continuously monitors mass loss with 1 mg readability and sub-0.01% moisture resolution. As the direct successor to the widely deployed MA30 platform, the MA150 retains full operational compatibility while delivering enhanced thermal uniformity, reduced footprint, and optimized energy transfer—enabling faster stabilization times and improved throughput for routine QC testing in pharmaceutical, food, chemical, and materials laboratories.

Key Features

• Compact benchtop design (213 × 320 × 180.5 mm; 5.5 kg) optimized for space-constrained lab environments without compromising structural rigidity or thermal stability.
• Ceramic infrared heating system with precise 1 °C adjustable temperature control across a broad 40–230 °C range, ensuring reproducible drying kinetics for diverse sample matrices—from hygroscopic powders to viscous pastes.
• Monolithic super dual-lever single-body sensor architecture delivers high linearity, minimal drift, and exceptional resistance to mechanical shock and thermal gradients—critical for long-term calibration integrity.
• Three configurable drying end-point modes: fully automatic (based on dynamic mass change threshold), semi-automatic (user-triggered stop), and time-controlled (programmable 0.1–99 min duration), supporting both standardized and application-specific protocols.
• GLP-compliant reporting with built-in thermal printer outputting audit-ready records including date/time stamp, operator ID, method name, initial/final mass, moisture %, dry weight %, ratio %, final dried mass (g), and mass per kg basis—all traceable to internal real-time clock and non-volatile memory.
• FDA 21 CFR Part 11 readiness via optional software configuration, enabling electronic signature support, user access levels, and immutable audit trails for regulated environments adhering to GMP or HACCP frameworks.

Sample Compatibility & Compliance

The MA150 accommodates samples up to 150 g with consistent performance across heterogeneous particulates, granules, tablets, pellets, slurries, and filter cakes. Its open-sample chamber design facilitates rapid loading and visual monitoring during drying, while the ceramic IR emitter ensures uniform irradiance distribution—minimizing surface charring or case-hardening artifacts common in halogen-based systems. The analyzer meets essential requirements of ISO 18810:2016 (moisture analysis by thermogravimetry), ASTM D4442 (wood moisture content), and USP <921> (Loss on Drying). Optional validation documentation packages—including IQ/OQ protocols, traceable calibration certificates (NIST-traceable weights), and uncertainty budgets—are available to support regulatory submissions and internal quality audits.

Software & Data Management

While the MA150 operates as a standalone instrument with intuitive membrane keypad navigation and real-time graphical display of mass vs. time curves, it supports RS232 serial communication for seamless integration into centralized LIMS or MES platforms. Exported data files (CSV format) include all measured and calculated parameters, along with metadata such as method ID, environmental temperature/humidity (if connected to external sensors), and operator-defined notes. Firmware updates are performed via USB interface, ensuring ongoing alignment with evolving analytical standards and cybersecurity best practices. All stored methods and results reside in protected memory with write-protection options to prevent accidental overwrites—supporting ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Pharmaceutical raw material release testing (excipients, APIs, granules) per ICH Q5C and compendial LOD specifications.
• Food ingredient QC—monitoring moisture in flour, sugar, dairy powders, spices, and pet food to ensure microbial stability and shelf-life compliance.
• Chemical manufacturing process control—verifying solvent residue levels in catalysts, resins, and polymer intermediates.
• Plastics and composites R&D—quantifying residual moisture prior to extrusion or injection molding to prevent hydrolytic degradation.
• Agricultural product grading—determining grain, seed, and feed moisture content in accordance with ISO 6496 and AOAC 950.46 methodologies.

FAQ

What standards does the MA150 comply with for regulated industries?

It supports implementation of ISO 18810, ASTM D4442, USP <921>, and EU GMP Annex 11 requirements when configured with appropriate validation and audit trail settings.
Can the MA150 be calibrated internally without external weights?

No—calibration requires certified NIST-traceable test weights; however, internal diagnostics and linearity verification routines are accessible via service mode.
Is the ceramic IR heater replaceable by the user?

Yes—the heater module is field-replaceable using standard tools and documented procedures; replacement parts carry full traceability and thermal certification.
Does the MA150 support multi-language UI?

The base firmware supports English and German; additional language packs may be installed via authorized service update.
How is data integrity ensured during power interruption?

All active measurements are automatically saved to non-volatile memory at 1-second intervals; upon restart, the unit resumes logging from the last recorded point without data loss.
