Parameter Increment
Description
Parameter Increment is a method development tool that
automatically makes stepwise increases in either vial
equilibration time or oven temperature for each subsequent vial
sampled.
During parameter incrementing, each vial is sampled and
returned to the carousel. The sampler displays NOT READY for
the duration of the GC Cycle Time between each increment. If
Vial Temp is incremented, the display reads WAITING FOR
READY until the new setpoint is reached.
The default values for both displays are 0.0, which means that
the parameter increment is off. The two parameters are
mutually exclusive: if a nonzero number is entered into one, the
other is automatically set to zero.
Oven Temp Step Entering a value for the Oven Temp Step
increases the Vial Temperature during vial equilibration by that
many degrees for the second vial and each subsequent vial in
the present method.
For example, enter an oven temperature step of 4 °C and run a
method with an oven temperature of 100 °C. The first vial has
an oven temperature of 100 °C, the second vial has an oven
temperature of 104 °C, and the third vial has an oven
temperature of 108 °C.
