Purge Flow Rate (ml/min) –
This setting is the rate at which the purge gas is
programmed to flow through the sample pathway during purge. The purge flow rate can
be programmed from 1 to 500mL/min in 1mL/min increments.
Programmable Purge Flow Control - < click> the Program button to enable this
feature. This feature can be used to change purge flow rates during the purge cycle. The
screen will appear as shown in Figure 3i. Check the
Enable Ramp Control box to
program the desired settings.
Initial Flow (ml/min) – This is the beginning purge flow rate programmed in
ml/min. The initial flow can be programmed from 0 to 500ml/min in 1ml/min
increments.
Initial Hold Time (min) – This is the time in minutes the initial flow is
maintained. The initial hold time can be programmed from 0 to 99.9 minutes in
0.1 minute increments.
Ramp Rate ((ml/min)/min) – This is the rate programmed in ml/min, the purge
flow will increase after the initial hold time has expired to the desired final flow
set point. The ramp rate can be programmed from 1ml/min to 500ml/min in
1ml/min increments.
Final Flow (ml/min) – This is the ending purge flow rate programmed in ml/min.
The final flow can be programmed from 0 to 500ml/min in 1ml/min increments.
Once the desired options are selected, <click> the Exit button to return to the
method parameters page.
