AlyTech's AURA II is a high-performance benchtop sampling unit designed for the controlled phase transition of LPG and liquefied gases.
The system ensures homogeneous, fractionation-free vaporization, providing a stable gas output for analysis by GC, microGC, GC/MS, or elemental analyzers.
When combined with the Aiolos GasMix™ system, AURA II enables automatic injection of gas and LPG samples and multi-point calibration from a single standard cylinder, improving reproducibility and saving time and consumables.
Operation and Software
AURA II combines regulated heating with pressure and flow control to provide a clean, stable gas phase.
- Automatic gas/LPG starts and multi-point calibration sequence
- Regulated output: 1–3 bar absolute (up to 4 bar), 20–200 cc/min
-
Heated transfer lines and switching valves for pressure/flow regulation
- Safety: Low-pressure operation and inlet safety valve
- Analyzer synchronization (GC, microGC, GC/MS, elemental analyzers).
Metrological Precision
Developed to ensure traceable performance and certified reproducibility, AURA II ensures maximum operational stability and reduces absorption for accurate quantification at trace levels. In synergy with Aiolos, it enables workflows compliant with ASTM D6667 and D7551 standards.
