Keys and Their Functions

Chain Methods

Allows two to four methods to be used sequentially to analyze groups of
samples in the tray. See "Chaining Methods" on page 65. Chaining methods is
not allowed if Parameter Increment is on.
For the G1289/G1290, chaining methods is one means of performing multiple
headspace extraction (MHE). See also "MULTI. HS EXTR." on page 49.

Link Methods

Press this key to sequentially "chain" two to four method together. See
"Chaining Methods" on page 65. Chaining methods is not allowed if Parameter
Increment is on.

Carousel Advance (G1883 only)

This key is used to move the sample tray for vial insertion and removal. The
cursor keys move the tray forward or backward by increments of one position.

Pressure (G1883/G1290 only)

This key displays the pressure of the carrier gas or the vial pressurization gas.
The carrier gas pressure is measured at the outlet of the flow controller. The
vial pressurization is measured at the outlet of the pressure regulator before
the in-line restrictor. It is a read-only display; no editing is allowed. Use the
cursor keys to scroll the display from the carrier gas to the vial pressurization
gas.

Tray Advance (G1289/G1290 only)

This key is used to move the sample tray for vial insertion and removal. Keying
in {vial position} and Enter moves that vial position to the "Home" position.
The home position in the tray is pointed out by an arrow silk–screened on the
oven. For easier access to vials for inserting and removing them, key in
{position + 4} and Enter to bring that position to the very front of the sample
