There will be always a wish from customers to
SPEED UP the analysis
Using Helium and different temperature program
Using Hydrogen
Using shorter, smaller ID columns
Using the same column, same GC
Column
: 100m x 0.25mm Rtx-DHA-100, df = 0.5 µm coupled with
2.6m x 0.25mm Rtx-5DHA tuning column, df = 1.0 um
• Carrier gas : He, Flow 2.3 mL/min (Constant Flow), 28 cm/s
• Oven temp. : 5 ºC → 15min., 5ºC/min → 50ºC, 50min.
8ºC/min → 200ºC, 10 min
