METTLER TOLEDO XPE Series Rapid Moisture Analyzer HX204 / HS153

Overview

The METTLER TOLEDO XPE Series Rapid Moisture Analyzer HX204 and HS153 are high-precision infrared moisture analyzers engineered for gravimetric moisture determination in regulated laboratory and production environments. Based on the loss-on-drying (LOD) principle, these instruments combine halogen heating technology with a thermally isolated Monobloc weighing cell to deliver repeatable, traceable, and compliant moisture results across diverse sample matrices — from hygroscopic pharmaceutical powders to granular food ingredients and industrial polymers. Unlike conventional top-loading moisture analyzers, the suspended pan architecture physically decouples the heating chamber from the weighing sensor, eliminating thermal drift induced by radiant heat transfer — a critical design factor for achieving sub-milligram stability during dynamic drying cycles. The HX204 variant features a 200 g capacity and 0.1 mg readability, supporting both routine QC testing and method development under stringent regulatory frameworks.

Key Features

• Suspended pan design with rear-mounted Monobloc weighing cell — isolates the load cell from thermal interference, ensuring long-term measurement stability and reproducibility.
• Second-generation halogen heating system — delivers rapid, uniform heating (0–160 °C range) with ±1 °C temperature control accuracy and minimal thermal inertia; enables consistent drying profiles regardless of instrument thermal state (cold-start or warm-start equivalence validated per ISO 8573-3).
• One Click™ Moisture interface — graphical, icon-driven workflow with real-time drying curve visualization, automated endpoint detection (slope-based or time-based), and color-coded pass/fail status (green/red) aligned with user-defined specification limits.
• IP54-rated enclosure with fully sealed pan support structure and flat-bottom cavity — facilitates complete residue removal in ≤30 seconds using standard lab wipes; no disassembly required.
• GLP/GMP-compliant operation — supports audit trails, electronic signatures, and user access levels when integrated with LabX software; meets FDA 21 CFR Part 11 requirements for data integrity in regulated industries.

Sample Compatibility & Compliance

The HX204/HS153 accommodates solid, semi-solid, and particulate samples ranging from 0.1 g to 200 g, including but not limited to active pharmaceutical ingredients (APIs), excipients, catalysts, resins, dairy powders, spices, and ceramic precursors. Its LOD methodology is formally recognized in multiple international standards: ASTM D4006 for petroleum products, USP for pharmaceutical moisture content, and ISO 8573-3 for compressed air humidity validation. All factory calibration procedures follow ISO/IEC 17025 traceability protocols, with optional NIST-traceable mass and temperature verification kits available. Instrument qualification packages (IQ/OQ/PQ) are provided to support GxP implementation.

Software & Data Management

While standalone operation is fully functional via the built-in touchscreen interface, full data governance is achieved through integration with METTLER TOLEDO LabX™ software. LabX enables centralized method management, automated report generation (PDF/CSV), secure cloud backup, and role-based permission controls. All raw drying curves, intermediate mass readings, temperature logs, and user actions are timestamped and cryptographically signed — satisfying ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Electronic records are exportable in formats compatible with LIMS and ERP systems without proprietary codec dependencies.

Applications

This analyzer serves as a primary moisture verification tool across quality control laboratories in pharmaceutical manufacturing (e.g., tablet blend uniformity checks), food safety testing (e.g., moisture specification compliance for flour or infant formula), chemical R&D (e.g., solvent residue quantification in polymer synthesis), and materials science (e.g., hydration state analysis of metal-organic frameworks). Its ability to resolve moisture changes below 0.01% w/w — combined with programmable multi-step drying protocols — makes it suitable for method transfer between R&D and production sites under ICH Q5C guidelines.

FAQ

Does the HX204 require external calibration weights for daily verification?
No — the instrument includes internal automatic calibration with motorized weight deployment; external weights are only required for periodic performance qualification (e.g., annual IQ/OQ).

Can the same method be deployed across both HX204 and HS153 models?
Yes — method files are cross-compatible within the XPE platform; however, maximum sample mass and resolution differ (HS153: 153 g / 0.1 mg).

Is halogen heating suitable for heat-sensitive biological samples?
Yes — precise ramp-and-hold temperature programming and real-time mass monitoring allow optimization of drying kinetics to minimize thermal degradation while maintaining quantitative water removal.

How is data integrity maintained during power interruption?
All active measurements are auto-saved to non-volatile memory at 1-second intervals; recovery resumes from last valid mass reading upon restart without data loss.
