Method 1615

Methyl Tert-Butyl Ether by GC/FID

This method is designed for the determination of MTBE (methyl tert-butyl ether) in gasoline and may be used for the determination of other components of gasoline. The sample is collected on charcoal sorbent tubes, desorbed with carbon disulfide, and analyzed by GC/FID. NOTE: This is a new method.
