– Accurate, Safe, and Easy-to-Use
Body:
In the petrochemical industry, the precise determination of aromatics, olefins, and saturates in liquid petroleum products is essential for quality control and process optimization. The DFYF-118 Hydrocarbon Determinator adopts the classic fluorescent indicator adsorption method, combined with multiple user-friendly and safety-focused designs, delivering efficient, reliable, and operator-friendly hydrocarbon analysis for modern laboratories.
1. Core Technology & Standard Compliance
The DFYF-118 is designed in strict accordance with GB/T 11132 – the standard test method for hydrocarbon types in liquid petroleum products by fluorescent indicator adsorption. It is suitable for automotive gasoline, aviation gasoline, solvent oils, naphtha, and similar products. This method is widely recognized by refineries and quality inspection agencies worldwide.
2. Key Components & Accurate Marking
Fluorescent Indicator + Specialized Silica Gel
The instrument is equipped with high-activity fluorescent indicator and dedicated silica gel packing, ensuring clear separation of hydrocarbon components within the adsorption column.
Magnetic Slider + External Position Marker
The separation layer is marked using a magnetic slider with an external indicator, providing precise positioning and excellent repeatability. More importantly, operators can complete the marking without touching the glass adsorption column, significantly reducing the risk of breakage and protecting hands from injury.
3. Optimized Structure for Simplified Operation
Co-located Power Supply and Experimental Area
The power components and experimental area are located on the same side, reducing the need to move the adsorption column frequently. This minimizes column damage and separation layer disturbance, improving test continuity and success rates.
Dual-Layer Pressure Protection Regulation
A built-in dual-layer pressure protection system effectively buffers pneumatic pressure fluctuations, preventing sudden pressure changes from damaging the adsorption column and extending the service life of consumables.
Quick-Connect Fittings for Reliable Air Circuit Connections
All pneumatic connections use industrial-grade quick-connect fittings – fast to install, easy to disconnect, and reliably sealed, eliminating leakage-related interference.
4. Operational Advantages at a Glance
