Setting the
Carrier Gas
Flow
The 1061 injector is equipped with type 3 Electronic Flow Control. With this
type of EFC a column flow of 0 - 100 mL/min may be set from the 3800
keyboard.
Flow Rates
for
Operation
Recommended flow rates differ, depending on the operating mode used.
Refer to the appropriate paragraph for your operational mode.
Capillary
Mode
When operating the injector in the capillary mode, the following carrier gas
flow rates are recommended:
Table 21 Carrier Gas Flow Rates for 1061
Carrier Gas
Column Flow Rate (Optimum)
Column Flow Rate (Typical)
Nitrogen
1.5 mL/min
3 - 15 mL/min
Helium
2.4-4.0 mL/min
4 - 15 mL/min
Hydrogen
4.0-8.0 mL/min
8 - 20 mL/min
Adjust the make-up gas flow to give a total of 30 mL/min.
Packed Mode
When operating in the packed column mode, adjust the carrier gas flow to
applicable packed column flow rates (20 to 50 mL/min).
1061 Operation
This section contains the specific operating information and procedures
required for optimum performance of the 1061 flash vaporization injector. All
installations for both the instrument and the injector must be completed
before continuing further. Note that the 1061 is equipped with Electronic
Flow Control as standard.
All EFC adjustments are made from the GC keyboard. The 1061 uses a type
3 EFC module which is a flow controller. The status feedback on the 3800
display is the column head pressure, actual flow rate, and the calculated
linear velocity.
1061 Injector
Method
The 1061 injector method component on the 3800 keyboard contains one
screen for setting the required temperature for the injector and viewing the
status information. The 1061 is an isothermal injector and cannot be
temperature programmed.
