Precisa XM60 Infrared Moisture Analyzer

Overview

The Precisa XM60 Infrared Moisture Analyzer is a precision-grade, halogen-heated thermogravimetric instrument engineered for rapid, reproducible moisture content determination in solid and semi-solid samples across pharmaceutical, food, chemical, and materials laboratories. Operating on the principle of loss-on-drying (LOD), the XM60 continuously monitors sample mass loss during controlled thermal drying and calculates moisture percentage relative to initial mass. Its integrated halogen lamp delivers uniform, responsive heating with fast thermal ramp rates—critical for minimizing decomposition artifacts in heat-sensitive matrices such as polymers, APIs, and botanical extracts. Designed and assembled in Switzerland, the XM60 complies with fundamental requirements of ISO 8573-3, ASTM D4457, and USP <921> for moisture analysis, supporting method validation under GLP and GMP frameworks.

Key Features

• Halogen heating system: Provides rapid, stable, and spatially homogeneous thermal energy—achieving setpoint temperature in under 60 seconds and enabling precise control across the full 30–230 °C range in 1 °C increments.
• Boost heating function: For accelerated start-up, the instrument applies up to 140% of the selected target temperature during the first three minutes—reducing total analysis time without compromising endpoint accuracy.
• High-resolution dual-display readout: Simultaneously shows real-time mass (0.001 g resolution) and moisture % (0.01% resolution) on a large, high-contrast green-backlit LCD—optimized for readability under ambient lab lighting conditions.
• Ergonomic pan handling: Features a dedicated, insulated lift handle integrated into the 90 mm diameter stainless-steel weighing pan—ensuring operator safety and preventing thermal transfer during hot-sample handling.
• GLP-compliant reporting: Built-in thermal printer supports traceable documentation including date/time stamp, operator ID, sample ID, method name, initial/final mass, moisture %, and drying curve summary—fully audit-ready.
• Configurable termination logic: Supports three independent drying end-point criteria: automatic (mass change threshold), semi-automatic (user-defined Δm/sec), or fixed-duration (0.1–240 min), allowing method flexibility across diverse sample types.
• Secure configuration management: Five user-programmable methods with password protection, physical lock slot, and encrypted parameter storage prevent unauthorized modification—essential for regulated QC environments.

Sample Compatibility & Compliance

The XM60 accommodates a broad spectrum of non-volatile and low-volatility samples—including powders, granules, pellets, pastes, and thin films—with optimal performance observed for masses between 0.5 g and 20 g. Its 62 g capacity and 0.001 g readability support both high-precision micro-moisture assays and routine batch testing. The instrument meets mechanical and electromagnetic compatibility requirements per IEC 61010-1 and EN 61326-1. All firmware and calibration routines are developed in accordance with ISO/IEC 17025:2017 clause 7.7 (Equipment) and align with FDA 21 CFR Part 11 expectations for electronic records—particularly when paired with optional audit-trail-enabled software packages.

Software & Data Management

Data export is facilitated via standard RS232 serial interface, compatible with LIMS integration, Excel-based reporting, and third-party laboratory data systems. The XM60 supports remote firmware updates through secure network-downloaded binaries—minimizing downtime during maintenance cycles and ensuring continuous alignment with evolving regulatory guidance. Internal memory retains all measurement metadata (including timestamped mass readings at user-defined intervals from 0.1 to 10.0 minutes), enabling post-run drying curve reconstruction and comparative kinetic analysis. Optional PC software provides advanced statistical evaluation, method synchronization across multiple units, and electronic signature capture for 21 CFR Part 11 compliance.

Applications

• Pharmaceutical raw material and excipient qualification per USP <921>
• Moisture verification in lyophilized products and tablet granulations
• Quality control of food ingredients (e.g., flour, dairy powders, coffee, spices)
• Residual solvent assessment in polymer resins and coatings
• Research-scale dehydration kinetics studies in academic and industrial R&D labs
• Environmental monitoring of hygroscopic reference standards and desiccant efficacy

FAQ

What is the typical drying time for a 1 g pharmaceutical powder sample?
Drying duration depends on target temperature and moisture volatility—but under standard 105 °C Boost mode, most API powders reach endpoint within 3–8 minutes.
Can the XM60 be calibrated for specific reference standards?
Yes—the instrument supports internal calibration using certified weights and external verification with NIST-traceable moisture standards (e.g., sodium tartrate dihydrate).
Is the RS232 interface compatible with modern Windows OS versions?
Yes, using a standard USB-to-RS232 adapter and terminal emulation software (e.g., Tera Term) or vendor-provided drivers.
Does the XM60 meet requirements for audit trails in regulated environments?
The base unit logs timestamps and method parameters; full 21 CFR Part 11 audit trail functionality requires optional PC software with electronic signature and change-history modules.
How often does the halogen lamp require replacement?
Rated lifetime exceeds 5,000 hours; typical replacement interval is 12–24 months under daily QC use—lamp status is monitored and reported during startup self-test.
