In automotive and industrial applications, fuel dilution within lubricating oil serves as a critical indicator of overall engine health, combustion efficiency, and potential fuel leakage. When elevated amounts of diesel fuel mix with engine oil, it severely degrades the oil’s lubrication performance, which can accelerate mechanical wear and ultimately lead to catastrophic and costly engine damage. Consequently, accurate and timely monitoring of these dilution levels is absolutely essential for executing proactive preventive maintenance and condition-based servicing.
To successfully address these rigorous industry demands, the GAS Fuel Diluents Analyser utilizes a robust, single-channel GC-FID setup optimized for heavy oil matrices. By intelligently implementing a backflush technique during the run, the system effectively expels the heavy oil fraction from the analytical column before it can cause contamination or baseline drift. This innovative approach not only protects the hardware but drastically slashes the typical analysis runtime to under two minutes. As a result, testing laboratories can achieve an exceptionally high daily sample throughput with minimal operator intervention and excellent analytical repeatability (below 5% RSD).
