SHYP DSH-50-1 Halogen Moisture Analyzer

Overview

The SHYP DSH-50-1 Halogen Moisture Analyzer is a precision benchtop instrument engineered for rapid, gravimetric determination of moisture content in solid and semi-solid samples via thermogravimetric analysis (TGA). It operates on the principle of controlled halogen lamp heating combined with high-stability weighing—measuring mass loss as a function of time and temperature to quantify volatile components, primarily free water. Designed for routine quality control and process validation in industrial and laboratory settings, the DSH-50-1 delivers consistent results across diverse matrices without requiring solvent extraction or complex calibration protocols. Its compact footprint, intuitive interface, and robust thermal architecture make it suitable for environments where throughput, operator efficiency, and measurement traceability are critical—particularly in food production, pharmaceutical raw material screening, chemical manufacturing, and agricultural commodity testing.

Key Features

• Halogen heating system enabling rapid, uniform thermal energy transfer—achieving target temperatures within seconds and reducing typical drying cycles to under 5 minutes for many standard samples.
• High-reliability隔热式称重传感器 (thermally isolated load cell) with 1 mg readability and ≤0.2% repeatability (tested with 3 g reference sample), minimizing thermal drift during active heating.
• Backlit dot-matrix LCD display providing simultaneous real-time readouts of moisture %, solid %, current mass, elapsed time, and chamber temperature—optimized for low-light lab conditions and multi-parameter monitoring.
• Six-key membrane keypad with direct-access functions—eliminating nested menu navigation and supporting one-touch start, pause, tare, and method recall.
• RS232 serial interface compliant with EIA/TIA-232 standards, enabling seamless integration with external printers, LIMS, or PC-based data acquisition software for audit-ready recordkeeping.
• Programmable drying profiles: user-defined temperature setpoints (50–180 °C, 1 °C resolution), heating duration (1–99 min, 10 s steps), and endpoint criteria (timed or auto-termination based on mass stabilization).

Sample Compatibility & Compliance

The DSH-50-1 accommodates heterogeneous solid and powdered samples ranging from 0.5 g to 10 g, including hygroscopic, thermally sensitive, and non-uniform materials such as granulated APIs, cereal grains, polymer pellets, mineral ores, filter papers, and lyophilized biologicals. Its 100 mm stainless-steel weighing pan ensures mechanical stability and easy cleaning. While not certified for GLP/GMP-regulated release testing per se, the instrument supports compliance workflows through its deterministic heating protocol, zero-point drift compensation, automatic tare functionality, and timestamped output—enabling alignment with internal SOPs referencing ASTM D4442 (moisture in wood), ISO 712 (cereals), USP <921> (loss on drying), and ICH Q5C (protein stability). Data integrity is reinforced by non-volatile memory retention of up to 20 user-defined methods.

Software & Data Management

The analyzer transmits ASCII-formatted measurement logs—including sample ID, start/end time, final moisture %, solid %, mass loss curve timestamps, and operator notes—via RS232 to host systems. When connected to validated third-party software (e.g., LabX, WinCT-Moisture, or custom Python/Excel VBA scripts), it supports automated report generation, statistical process control (SPC) charting, and electronic signature capture. All communications adhere to standard serial framing (9600 baud, 8N1), facilitating compatibility with legacy lab infrastructure. Audit trails—comprising method parameters, environmental conditions (ambient temp/humidity logged externally), and raw mass vs. time datasets—are exportable for FDA 21 CFR Part 11-compliant review when paired with appropriate software controls.

Applications

• Food & Feed: Rapid verification of moisture in flour, spices, dairy powders, and pet food to ensure shelf-life compliance and prevent microbial proliferation.
• Pharmaceuticals: Pre-release screening of excipients (e.g., lactose, microcrystalline cellulose) and active ingredients per USP <921> LOD specifications.
• Chemicals & Polymers: Quantification of residual solvents or hydration water in catalysts, resins, and battery electrode materials.
• Agriculture & Forestry: Field-lab assessment of grain moisture for storage classification (e.g., ISO 6540) and timber seasoning verification.
• Paper & Textiles: Determination of moisture regain in pulp, paperboard, and synthetic fibers to calibrate drying line parameters.

FAQ

What is the maximum sample weight the DSH-50-1 can handle?

The instrument has a maximum capacity of 50 g, but optimal accuracy is achieved with recommended sample masses between 3 g and 10 g.
Does the DSH-50-1 support automatic endpoint detection?

Yes—it offers both timed termination and dynamic endpoint detection based on mass change rate thresholds, configurable via front-panel settings.
Can the halogen lamp be replaced by the user?

The halogen heating module is field-replaceable using standard M4 screws and OEM-specified lamps (SHYP P/N HAL-12V/100W); no recalibration is required post-replacement.
Is calibration traceable to national standards?

While the unit itself does not include built-in NIST-traceable calibration, it accepts external Class F1 or better weights (e.g., 10 g, 20 g) for daily performance verification per ISO/IEC 17025 guidelines.
How is temperature uniformity ensured across the sample pan?

The halogen emitter is optically aligned and thermally coupled to a reflective aluminum heat diffuser, achieving ±2.5 °C spatial uniformity over the central 80 mm diameter at 105 °C, verified per ASTM E2251.
