SHYP DSH-50-10 Halogen Moisture Analyzer

Overview

The SHYP DSH-50-10 Halogen Moisture Analyzer is a precision thermal gravimetric instrument engineered for rapid, reliable determination of moisture content in solid and semi-solid materials. It operates on the principle of loss-on-drying (LOD), where a precisely weighed sample is subjected to controlled halogen lamp heating under defined thermal conditions; moisture evaporation is tracked via real-time mass measurement until stabilization—enabling calculation of moisture percentage based on initial and final mass. Unlike conventional oven-drying methods requiring hours, the DSH-50-10 achieves typical analysis times between 3–15 minutes, depending on sample type and target temperature. Its halogen heating system delivers uniform radiant energy with fast thermal response and excellent spatial consistency across the 100 mm diameter sample pan—critical for minimizing edge effects and ensuring reproducible drying kinetics. Designed for routine QC/QA environments, the analyzer complies with fundamental method validation requirements outlined in ASTM E1447, ISO 712, and USP <921>, supporting both standardized and user-developed drying protocols.

Key Features

• High-resolution backlit dot-matrix LCD display with intuitive menu navigation—optimized for low-light laboratory or production floor use.
• Halogen lamp heating module offering rapid thermal ramp-up, precise temperature control (50–180 °C in 1 °C steps), and stable plateau maintenance throughout the drying cycle.
• Thermally isolated high-precision load cell (10 mg readability, 50 g capacity) with zero-point drift compensation and automatic tare functionality for sequential multi-sample analysis.
• Dual endpoint detection: programmable timed mode for fixed-duration assays, and automatic mode triggered by mass change threshold (e.g., ≤0.1 mg/10 s), minimizing operator bias.
• RS232 serial interface compliant with standard ASCII command protocols—enabling seamless integration with LIMS, ERP systems, or local data loggers for audit-ready recordkeeping.
• Robust mechanical architecture with aluminum alloy housing, vibration-dampened weighing chamber, and removable stainless-steel pan for easy cleaning and cross-contamination prevention.

Sample Compatibility & Compliance

The DSH-50-10 accommodates a broad spectrum of industrial and research-grade samples including pharmaceutical excipients, granulated APIs, cereal grains, mineral ores, polymer pellets, paper pulp, dried botanicals, and food powders. Its 0.5 g minimum sample requirement supports testing of high-value or limited-availability materials. The instrument meets essential functional criteria for GLP and GMP-regulated environments: all measurements are traceable to internal calibration routines, and time-stamped results—including intermediate mass readings at user-defined intervals—can be exported for review. While not inherently 21 CFR Part 11 compliant out-of-the-box, its RS232 output enables connection to validated third-party software platforms that provide electronic signature, audit trail, and role-based access control per regulatory expectations.

Software & Data Management

Data acquisition and reporting are fully configurable via front-panel controls—no PC required for basic operation. The built-in memory stores up to 20 user-defined methods, each specifying target temperature, heating duration, endpoint logic, and display preferences (moisture %, solids %, residual weight, elapsed time, current temperature). When connected to external hardware, raw mass-vs.-time datasets and summary reports (CSV or TXT format) are transmitted in real time. Compatible terminal emulators or custom scripts can parse timestamps and trigger automated pass/fail decisions against pre-set moisture limits—supporting statistical process control (SPC) workflows. All exported files retain full metrological context, including instrument ID, operator code (manually entered), and environmental ambient reading (10–30 °C operating range).

Applications

• Pharmaceutical manufacturing: verification of drying endpoints for wet granulation, fluid-bed drying, and lyophilization cycle validation.
• Food quality assurance: monitoring moisture in flour, sugar, dairy powders, and snack coatings to ensure shelf-life stability and microbial safety.
• Agrochemical and feed production: batch release testing of fertilizers, animal feed pellets, and pesticide formulations per AOAC 952.04 guidelines.
• Materials science labs: characterization of hygroscopicity in battery electrode slurries, ceramic green bodies, and composite resins.
• Environmental testing services: quantification of moisture in soil extracts, sludge samples, and contaminated sediments prior to heavy metal extraction.

FAQ

What standards does the DSH-50-10 support for moisture testing?

It aligns with core principles of ASTM E1447 (standard test method for moisture in solids by thermogravimetry), ISO 712 (cereals and cereal products), and USP <921> (water determination), though method validation must be performed per application-specific SOPs.
Can the instrument be calibrated internally without external weights?

Yes—it includes internal calibration routines using factory-traceable reference masses; however, external verification with certified weights (Class M2 or better) is recommended quarterly or after relocation.
Is the halogen lamp replaceable by the end user?

Yes—the lamp assembly is field-serviceable with standard tools; replacement parts and torque specifications are documented in the technical manual.
Does the analyzer support multi-step heating programs?

No—the DSH-50-10 implements single-stage heating only; multi-ramp profiles require external programmable ovens or higher-tier models with advanced thermal sequencing.
How is temperature uniformity verified across the sample pan?

SHYP provides a thermal mapping report upon request, conducted using NIST-traceable infrared thermography under nominal operating conditions (100 °C, center and edge positions).
