Conforms to the specifications established in the current ASTM method D3606 for the quantitation of benzene and toluene in spark ignition fuel containing ethanol.
The inlet is identified on both column 1 and column 2. Note: The inlet of column 2 is identified for proper orientation for connection to the valve.

Features & Benefits
- Accurate quantification of toluene and benzene—including benzene in gasoline containing ethanol or butanol blends.
- Complete resolution of benzene from ethanol—no compromising coelutions.
- Enhanced formulation with improved support material and polymers—more robust and reproducible.
- Column sets are individually tested for D3606 method applicability.
- QC test chromatogram includes approximate backflush times.
- Listed in the ASTM Method D3606—attain better separation of benzene and ethanol while following ASTM method requirements.
- Exclusively available from Restek. Includes Column 1: backflush column, 6′ (1.8 m), 1/8″ OD, 2.0 mm ID; Column 2: proprietary packing, 15.5′ (4.7 m), 1/8″ OD, 2.0 mm ID.
Note: Our current D3606 column set (cat.# 83606A) requires a longer backflush time. Please refer to the QC certificate for the approximate backflush time.
