Overview
The TimePower TP662 Automatic Distillation Apparatus is a fully integrated, ASTM D86-23 and ISO 3405 compliant distillation system engineered for precise determination of boiling range distributions in petroleum products and volatile organic liquids. It operates on the principle of standardized atmospheric distillation—where a representative sample is heated under controlled conditions, and vapor-phase temperature and condensed liquid volume are recorded continuously as distillate is collected in calibrated increments. The instrument implements a closed-loop thermal management architecture: a Danfoss (Secop) hermetic compressor enables rapid, stable cold bath regulation (0–60 °C), while dual Pt100 platinum resistance thermometers (traceable to NIST standards) monitor both vapor temperature and recovery chamber ambient conditions. Real-time atmospheric pressure sensing ensures automatic correction of observed temperatures to standard atmospheric pressure (101.3 kPa), satisfying regulatory requirements for reporting in accordance with ASTM D1298 and IP 288.
Key Features
- 10.4-inch high-resolution color touchscreen interface with intuitive workflow navigation and real-time graphical display of temperature–volume curves.
- Imported optoelectronic volume tracking system with 0.1 mL resolution and ±0.1 mL measurement repeatability across full 1–111 mL range.
- Programmable termination logic: test concludes automatically upon reaching either user-defined steam temperature threshold or cumulative recovered volume limit.
- Integrated nitrogen purge and manual emergency shutoff valve for inerting the distillation flask—mitigating fire risk during high-boiling or unstable fraction analysis.
- Modular firmware architecture supporting firmware updates via USB; all calibration parameters stored in non-volatile memory with tamper-evident audit trail.
- Recovery chamber temperature stabilization (10–40 °C adjustable) minimizes condensation variability and improves volumetric accuracy per ASTM D86 Annex A1.
Sample Compatibility & Compliance
The TP662 is validated for use with gasoline, aviation gasoline (AVGAS), jet fuels (Jet A, Jet A-1), naphthas, kerosene, diesel fuels, solvent naphthas, and industrial-grade organic solvents (e.g., toluene, xylene, acetone). It conforms to key international test methods including ASTM D86 (Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure), ASTM D1078 (Volatility of Volatile Organic Liquids), ISO 3405, and GB/T 6536 (Chinese national equivalent). All thermal and volumetric measurements meet traceability requirements for GLP-compliant laboratories; optional 21 CFR Part 11–enabled software module provides electronic signatures, user access control, and immutable audit logs for regulated environments.
Software & Data Management
Instrument control, data acquisition, and report generation are managed through embedded firmware with optional PC-based TimePower DistilSoft v3.x. Raw data—including time-stamped temperature, volume, and pressure values—is exported in CSV and XML formats compatible with LIMS integration. Calibration records, maintenance logs, and method templates are stored with date/time stamps and operator ID. The system supports multi-user role assignment (administrator, analyst, reviewer) and includes built-in validation tools for temperature sensor linearity verification and volume tracker linearity checks per ISO/IEC 17025 Clause 6.5.
Applications
- Quality assurance of refinery cut points in crude distillation units (CDUs) and hydrotreaters.
- Verification of volatility specifications for automotive and aviation fuels per ASTM D4814 and DEF STAN 91-91.
- Boiling point distribution analysis of hydrocarbon solvents used in coatings, adhesives, and pharmaceutical extraction processes.
- Research-scale investigation of thermal stability and fractional composition in biofuels and synthetic blendstocks.
- Compliance testing for environmental regulations requiring Reid Vapor Pressure (RVP) correlation and distillation curve modeling.
FAQ
Does the TP662 comply with ASTM D86 for referee testing?
Yes—the system meets all mechanical, procedural, and data recording requirements specified in ASTM D86-23, including vapor temperature measurement location, still-head design, and condenser cooling specifications.
Can the instrument be validated for 21 CFR Part 11 compliance?
With optional DistilSoft v3.x and hardware security module, full Part 11 functionality—including electronic signatures, audit trail, and access control—is supported.
What maintenance is required for long-term accuracy?
Annual verification of Pt100 sensor calibration against certified reference standards and quarterly cleaning of optical path surfaces in the volume detector are recommended.
Is external atmospheric pressure input required?
No—the integrated barometric sensor continuously measures local pressure and applies real-time corrections to all reported temperatures.
How is safety ensured during high-temperature distillation of unstable samples?
The manual nitrogen purge valve allows immediate inerting of the distillation flask; combined with overtemperature cutoff and flame-retardant housing materials, it satisfies IEC 61010-1 safety requirements for laboratory equipment.
