The Agilent 6890 has on-board sensors that automatically compensate for ambient temperature changes and barometric pressure differences. These sensors allow for more accurate and reproducible results. Overall thermal performance of the Agilent 6890 GC provides optimal chromatography including peak symmetry and retention index accuracy while delivering fast results. The Agilent 6890 GC is capable of producing accurate temperature readings with outstanding retention time repeatability, which is the basis for all chromatographic measurements.
The FTO system analyzes streams with concentrations of 0.2%-35% olefins. This GC system determines C4 - C10 olefins in all finished motor gasolines, straight naphthas and FCC naphthas. It reports in weight % and liquid volume % and a full analysis takes just 20 minutes. The FTO analysis exceeds the repeatability capabilities of ASTM D 1319 (the Fluorescent Indicator Absorption-FIA-method) and incorporates ASTM D 6296 - Total Olefins in Spark-Ignition Engine Fuels by Multi-Dimensional GC.
