ASTM D7345 Micro Distillation Analyzer MDR5100

Engineered for laboratory benchmarking and rugged on-site inspection, this automated micro distillation analyzer delivers rapid atmospheric boiling range characteristics for petroleum products. Fully compliant with ASTM D7345 and NB/SH/T 6071 standard test methods, the instrument produces results that demonstrate true thermodynamic correlation with traditional glass distillation procedures, meeting the stringent repeatability and reproducibility mandates of ASTM D86 and GB/T 6536.

Micro-Volume Efficiency and Rapid Cycle Times

Operating on a minimal 10 mL specimen volume, this micro distillation unit reduces hazardous hydrocarbon consumption and disposal overhead by up to 90% compared to standard 100 mL distillations. A complete distillation curve from initial boiling point (IBP) to final boiling point (FBP) across a temperature range of 0 to 400°C is generated within 15 minutes, dramatically accelerating refining release workflows, blend verification, and intake screening.

One-Touch Automation and Integrated Diagnostics

The system features true one-button automated operation. Advanced microprocessor monitoring oversees heating rate regulation, sensor calibration, optical meniscus tracking, and vapor pressure stabilization without manual user intervention. Intelligent onboard algorithms correct barometric variance and translate boiling behavior into predictive metrics, including integrated closed-cup flash point calculation for middle distillates, diesel, and aviation fuels.

Field-Ready Architecture for Mobile Deployment

Weighing just 13.5 kg with an ultra-compact bench footprint (33 × 28 × 35 cm), the chassis is built to withstand mechanical vibration in mobile laboratories and vehicle-mounted field units. Direct USB and RS232 digital interfaces ensure seamless integration with plant Distributed Control Systems (DCS) and Laboratory Information Management Systems (LIMS) for automated data archiving.

Technical Specifications

Frequently Asked Questions (FAQ)

1. How does ASTM D7345 micro distillation compare with traditional ASTM D86 results?

ASTM D7345 micro distillation exhibits direct physical correlation with ASTM D86 and GB/T 6536, providing equivalent boiling curve points while meeting the repeatability and reproducibility criteria specified in ASTM D86.

2. What volume of fuel sample is required for a complete distillation curve?

The instrument requires only 10 mL of liquid sample per run, representing a 90% reduction in sample consumption compared to standard 100 mL distillation glassware setups.

3. How long does a typical sample analysis take from start to finish?

A full analytical run takes 15 minutes or less, facilitating immediate batch release, rapid product identification, and high sample throughput in fast-paced testing laboratories.

4. Can this unit predict closed-cup flash point values for tested samples?

Yes, the onboard processor calculates and predicts closed-cup flash point temperatures for diesel, kerosene, jet fuel, and biodiesel based on initial distillation characteristics.

5. Is the flash point prediction function suitable for volatile gasoline?

No, due to the high volatility and unique vapor composition of light gasoline, flash point estimation is specifically configured for middle distillates and heavy fuel fractions.

6. Can this analyzer be installed and operated inside a vehicle or mobile lab?

Yes, with a compact footprint of 33 × 28 × 35 cm and a net weight of only 13.5 kg, the ruggedized housing is suited for vehicle mounting and rapid field deployment.

7. Does the operator need to adjust heating rates or condenser settings manually?

No, the instrument features one-step operation with fully automated heating control, vapor detection, and intelligent curve calculation that eliminates operator-induced error.

8. What petroleum fuel products can be analyzed using this system?

The system analyzes finished gasoline, diesel fuel, aviation turbine fuels, synthetic jet fuels, kerosene, biodiesel blends, and light-to-middle petroleum distillate fractions.

9. What external laboratory utilities are needed to run the analyzer?

The analyzer requires only standard AC 220V single-phase electrical power and does not require external cooling water chillers, high-pressure gas cylinders, or vacuum lines.

10. How are test reports exported to external data management networks?

Test reports and distillation curves are exported digitally via dedicated RS232 and USB serial ports directly to printers, personal computers, or LIMS databases.

11. How does micro-volume testing benefit laboratory safety and operating costs?

Analyzing 10 mL samples reduces fire hazards, limits toxic vapor generation in the work area, lowers ventilation requirements, and minimizes hazardous waste disposal expenses.

12. Does the unit automatically correct distillation temperatures for atmospheric pressure?

Yes, the analyzer includes an internal high-precision barometric pressure sensor that automatically normalizes all distillation temperature readings to standard atmospheric pressure (101.3 kPa).
