ColumnD3606 application column (2 column set). Column 1: Sulfinert tubing, 6 ft (1.8 m), 2.00 mm ID, 0.125 in OD; Rt-D3606-1 proprietary packing material. Column 2: Sulfinert tubing, 15.5 ft (4.7 m), 2.00 mm ID, 0.125 in OD; Rt-D3606-2 proprietary packing material (cat.# 83606A-800)
SampleGasoline (87 octane with ethanol) spiked with internal standard (IS)
Conc.: Neat
Injection
Inj. Vol.:1.5 µL packed not on-column
Liner:Topaz 2.0 mm ID straight inlet liner (cat.# 23313)
Inj. Temp.:200 °C
Oven
Oven Temp.:135 °C (hold 15 min)
Carrier GasHe, constant flow
Flow Rate:25 mL/min @ 135 °C
DetectorTCD @ 200 °C
InstrumentAgilent/HP6890 GC
NotesValve box temperature: 150 °C
Backflush (valve) times for this column set are:
• Valve on at ~4.3.0 minutes
• Valve off at 12.0 minutes
Note that backflush times must be determined for each GC system. To determine the backflush time, analyze ASTM backflush standard (cat. # 30671) following the procedure described in the instruction sheet for the D3606 column set. Then, multiply the result by the algorithm 2.33.
