SFC Instrumentation manufacturer reports outstanding sales growth in fuels market

Sep 05 2019 Read 251 Times

The dedicated team at Selerity Technologies has achieved outstanding industry support across North and South America in 2019, by providing robust instrumentation solutions for alternative methods to ASTM D1319, the standard method for measuring total saturates, aromatics and olefins in gasoline, aviation turbine and diesel fuels by fluorescence indicating absorbance (FIA). The urgent need for replacement of the FIA technique has significantly increased demand for the Selerity Series 4000 turn-key supercritical fluid chromatograph, equipped with straightforward flame ionization detection (SFC-FID) for measuring total olefins in gasoline (ASTM D6550) and total aromatic and polynuclear aromatic hydrocarbons in diesel fuels (ASTM D5186).

Supercritical fluid chromatography has been proven to be a viable and attractive technique for the petroleum industry due to the solvating power of supercritical carbon dioxide and use of a flame ionization detector (FID). The FID is an optimal mass detector for hydrocarbon analysis due to its high sensitivity, providing a reliable linear response across the mass range. The analytical methods for determining total aromatic hydrocarbon concentrations in aviation and diesel fuels are extremely simple, normalized methods with no sample dilutions, no derivatizations, no calibrations and no response factor manipulations due to changes in concentration.

One configured Selerity Series 4000 SFC-FID system provides analysis for three different methods: ASTM D6550, D5186, and the proposed new ASTM method for total aromatic and naphthalene hydrocarbons in aviation turbine fuels. Thus, the Selerity Series 4000 has become the alternative chromatographic system of choice to replace the FIA. Selerity’s expert team has over thirty years of extensive SFC-FID experience, providing comprehensive chromatography support: hardware and application guarantee for each SFC, a full line of consumables, technical support and training, with onsite services and custom service contracts.
