Columns and inlets
The GC, with an EPC inlet, allows you to specify gas flow through capillary
columns directly. To use this feature:
1. Configure the column (supply length, inside diameter, and film thickness).
2. Configure the carrier gas. (What gas are you using?)
3. Select a column mode (constant flow or pressure, ramped flow or pressure).
4. Enter the initial flow or pressure or average linear velocity.
5. Enter a flow or pressure program (optional).
6. Enter the rest of the inlet parameters.
