The SF-16A rod-like thin-layer chromatography system represents a significant breakthrough in laboratory instrumentation, developed over many years by Yamaha Instruments. This advanced device is primarily designed for the analysis and testing of complex substances such as crude oil, heavy oil, residual oil, wax oil, oil slurry, lubricating oils, chromatographic fixing fluids, and greases. With its innovative technology, the SF-16A can rapidly analyze samples for saturated hydrocarbons, aromatic compounds, gums, and asphaltenes within just two hours. This represents a remarkable reduction in analysis time—saving up to 96% compared to traditional solvent elution methods, which typically require 48 hours per sample. Furthermore, the SF-16A operates using a fully enclosed process, eliminating the need for operators to handle harmful or toxic solvents. This ensures the safety and well-being of users while drastically reducing operational costs to just 1% of conventional solvent-based methods.
The latest version of the SF-16A incorporates cutting-edge technologies like electronic flow control and precision CNC machining. Its user-friendly, large-screen Chinese-language touchscreen interface enhances both data reliability and overall instrument performance.
Key Features of the SF-16A Rod TLC System:
- **Convenience**: Easy-to-use design with fast analysis speeds, short cycles, and highly accurate data.
- **Eco-Friendly**: Utilizes toluene as a solvent in minimal amounts, significantly reducing environmental impact and ensuring safer working conditions for operators.
- **Cost-Effective**: Chromatographic rods are reusable up to 50 times, minimizing solvent usage and drastically lowering operating expenses.
- **Versatility**: Capable of directly detecting a wide range of organic compounds, including those with higher boiling points that are challenging for gas chromatography. Applications span industries such as pharmaceuticals, environmental science, petrochemicals, petroleum geology, coal chemistry, and specialty chemicals.
How Does the Instrument Work?
Samples of crude oil, heavy oil, residual oil, wax oil, oil slurry, lubricating oil, chromatographic fixatives, and grease are first diluted with thinner and applied to silica-alumina-coated rods. These rods are then placed in a chromatographic expansion tank where they undergo separation under controlled temperature and humidity conditions. As the separated samples pass through the detector, they are scanned at adjustable speeds between 50-500 mm/min. The resulting ion stream signals are captured and processed by a computer to generate the final analysis results.
