User Benefits

- Quantitation of benzene and toluene in fuels based on ASTM D3606 is possible. - Highly accurate backflush analysis is possible by using the SMI flow device. - The compact design of the Brevis GC-2050 enables space-saving in the laboratory.

Introduction

Benzene and toluene are widely used as feedstocks for chemical products, but due to concerns about their effects on human health, the permissible concentrations of these two compounds are specified in various regulations. ASTM D3606 provides two quantification methods (Procedures A and B) for benzene and toluene in automotive fuels. The corresponding concentrations of benzene and toluene are 0.12-5.2Vol% and 0.4-19.7Vol% when using Procedure A and 0.10-5.0Vol% and 2.0-20.0Vol% when using Procedure B. In this Application News article, benzene and toluene were quantified by Procedure A in ASTM D3606. Satisfactory linearity of the calibration curves and reproducibility of the quantitation values could be obtained for both compounds.
