Anton Paar Diana 700 Atmospheric Distillation Analyzer

Overview

The Anton Paar Diana 700 Atmospheric Distillation Analyzer is a fully automated, ASTM D86-compliant distillation system engineered for precise and reproducible boiling point distribution analysis of petroleum products and volatile organic liquids under ambient pressure conditions. Based on classical batch distillation principles—where a sample is heated at controlled rates while vapor temperature and condensed volume are continuously recorded—the Diana 700 implements rigorous thermal management, real-time volumetric tracking, and fail-safe procedural logic to ensure method adherence and measurement integrity. Designed specifically for laboratories performing routine fuel testing (e.g., gasoline, diesel, jet fuel, naphthas, solvents, and aromatic hydrocarbons), it delivers traceable, auditable results aligned with international standard test methods including ASTM D86, ISO 3405, IP 123, and GB/T 6536. Its modular architecture integrates heating, cooling, condensation, volumetric detection, and data acquisition into a single compact platform, minimizing operator intervention while maximizing repeatability across shifts and operators.

Key Features

• Fully automated distillation sequence—from sample loading to final report—with intelligent step validation ensuring all preconditions (e.g., bath temperature stabilization, sensor calibration verification, correct flask type recognition) are met before initiation.
• One-hand quick-connect flask mounting system with integrated positioning bracket and auto-recognized 125 mL or 200 mL ASTM-standard distillation flasks; eliminates misalignment and reduces setup time to <5 seconds.
• Motorized heater and safety shield actuation: the shield rises automatically upon flask placement and only permits distillation when proper flask and support plate configuration is confirmed via embedded RFID or mechanical encoding.
• Peltier-cooled receiving chamber with programmable temperature control (0–80 °C), enabling rapid thermal equilibration between ASTM D86 Group I–IV tests in ≤5 minutes; integrated desiccant cold trap minimizes moisture ingress and VOC loss during condensation.
• High-stability volumetric detection using Contact Image Sensor (CIS) technology—solid-state optical imaging with 0.01 mL resolution—capable of real-time meniscus tracking and automatic initial volume normalization to 100%.
• Embedded calibration memory: temperature sensor calibration coefficients are stored directly on the probe; recognized and applied automatically upon insertion, eliminating manual calibration entry errors.

Sample Compatibility & Compliance

The Diana 700 is validated for use with light to medium petroleum fractions and volatile organic compounds exhibiting initial boiling points ≥30 °C and final boiling points ≤450 °C. Compatible sample types include unleaded gasoline, aviation turbine fuels (Jet A-1, JP-8), diesel fuels (EN 590, ASTM D975), kerosene, naphtha, toluene, xylene, and technical-grade solvents. All operational parameters—including heating rate profiles, vapor temperature sampling intervals, and volume collection timing—are configurable to meet exact requirements of ASTM D86 (Method A/B/C), ISO 3405 (2016), IP 123, and related regional specifications. The system supports GLP/GMP-aligned workflows through secure user access levels, electronic signatures, and full audit trail logging compliant with FDA 21 CFR Part 11 requirements when paired with Anton Paar’s TruSight software suite.

Software & Data Management

Controlled via Anton Paar’s intuitive TruSight™ software, the Diana 700 provides role-based user interfaces: Guided Mode offers illustrated, step-by-step instructions ideal for new operators, while Expert Mode displays real-time status of all subsystems (heater, cooler, CIS sensor, shield position, flask ID) for advanced diagnostics and method tuning. All raw data—including time-stamped vapor temperature, recovered volume, and calculated % recovery—are stored in encrypted .csv and proprietary .trud files with embedded metadata (operator ID, method version, calibration timestamps). Data export supports LIMS integration via ASTM E1384-compliant formats and includes optional digital signature workflows for regulatory submission readiness.

Applications

• Quality control of refinery streams and finished fuels per ASTM D86 specifications.
• Boiling point distribution profiling for formulation optimization in petrochemical R&D.
• Compliance verification against transportation fuel standards (e.g., EN 228, ASTM D4814).
• VOC content estimation and volatility assessment for environmental reporting (EPA Method 25A, ISO 11843).
• Stability evaluation of solvent blends used in coatings, adhesives, and cleaning formulations.
• Training and method validation in accredited testing laboratories pursuing ISO/IEC 17025 accreditation.

FAQ

Does the Diana 700 comply with ASTM D86 Method A, B, and C?

Yes—it supports all three distillation procedures through programmable heating ramp profiles, vapor temperature monitoring intervals, and receiver bath temperature settings.
Can the system be used for samples outside the petroleum sector, such as biofuels or synthetic lubricants?

It is suitable for any volatile liquid with boiling range within 0–450 °C and viscosity compatible with ASTM D86 flask geometry; validation per relevant method (e.g., ASTM D7892 for biodiesel) is required.
Is remote monitoring or network integration supported?

Yes—via Ethernet connection and TruSight software, multiple instruments can be centrally monitored and controlled through a laboratory network; OPC UA and REST API options are available for enterprise-level integration.
How often does the CIS volume sensor require recalibration?

The CIS module is factory-calibrated and drift-compensated; Anton Paar recommends annual verification using certified volumetric standards traceable to NIST or PTB.
What safety certifications does the instrument carry?

The Diana 700 complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and bears CE, UKCA, and cULus marks for global deployment.
