Analysis of Methyl-t-Butyl Ether (MTBE) and related impurities per ASTM test method D5441 using Zebron™ ZB-DHA-PONA Gas Chromatography Column

Abstract:

Methyl-t-Butyl Ether (MTBE) is used as an additive for spark ignition fuels to enhance the octane performance. MTBE is a distilled product with a designed low amount of impurities, and the ASTM D5441 is a gas chromatography analysis method that is used to measure its purity. Running this test method verifies that no impurities were left during the manufacture of the MTBE nor were any contaminants introduced in its storage or shipment. The purity of the MTBE is critical since any contamination will affect the performance of the spark ignition fuel. In this technical work ASTM D5441 is run with the Zebron™ ZB-DHA-PONA gas chromatography column which is specially designed for the DHA test methods. A side by side comparison of commercially available columns are made to evaluate the peak shape and the separation of critical pairs.
