Setting Up Oven and Inlet Temperature Programs
The Clarus GC software allows you to set up to four-ramp programs (they are 0 [isothermal], 1, 2, or 3).
1. From the System Status screen touch the oven icon to modify the program.
2. Once the oven program screen appears.
3. Select a field by touching it and use the up and down arrow or keypad buttons to
enter a temperature, equilibration time and rate. When the word END appears in the rate field all
the fields that follow are deactivated. You must touch END and then touch the plus (+) button to
activate the next row. The following figure shows a typical temperature step program.
Before you actually set up an oven temperature program, you should decide on the Equilibration Time you
need and change the default value (2 minutes) if necessary (see below).
Configuring the Equilibration Time (Init)
When you change the oven temperature setpoint, the system heats or cools the oven to the new setpoint,
then equilibrates the column(s) for the specified Equilibration Time before the instrument becomes READY.
NOTE: A minimum Equilibration Time of 2 minutes is recommended for temperature programs. Longer
equilibration times are recommended for initial oven temperatures of < 50°C. An equilibration time of 0.0
minutes can be used for isothermal methods.
