Entering a Method
This chapter details the procedure for entering a method, including storing and
retrieving a method, and chaining methods.
Entering a Method
To enter a method for the 7694 Headspace Sampler via the keypad, setpoints
must be set for the keys labeled Zone Temps, Event Times, and Vial
Parameters. Each of these keys has a number of setpoints associated with it.
The cursor keys (
▲,▼ ) scroll up and down through the list of setpoints. To enter
a value for a setpoint, scroll to that setpoint, key in the value using the numeric
keypad, then press Enter. If the value keyed in is not within the allowed range,
the sampler displays a message showing the allowed range. Pressing any non–
number key removes the error message. If the value keyed in is not the one
desired, pressing Clear returns you to the top level of the display.
Entering Zone Temps
This key allows you to enter values for the oven temperature, loop
temperature, and transfer line temperature. Press Zone Temps. The sampler
displays the following:
Key in the desired value for the oven temperature setting followed by Enter.
The allowed range for this setting is 0-200°C (40–200°C for G1883).
Caution The oven temperature should not exceed 10°C below the boiling point of any
solvent in the vial. Exceeding this may cause the cap and septum to leak or to
pop off.
