Description

Ambient

0°C

450°C in
increments of 1.

² (Demo
mode: 24°C)

Temperature in the laboratory. (The property is available only if Cryo is selected on the Options configuration tab page.)

Cryo

Off

On

² (Demo
mode: Off)

If set to On, the cryogenic valve operates automatically. If set to Off, the valve is disabled. (The property is available only if Cryo is selected on the Options configuration tab page.)

CryoFault

Off

On

Off

The oven shuts down if it does not reach the set point temperature after the time specified for cryo operation. (The property is available only if Cryo is selected on the Options configuration tab page.)

CryoTimeout

0 min

999.99 min
in 0.01 increments

² (Demo
mode: 0.00 min)

Indicates the time that the GC waits before turning off the cooling if no sample has been injected.

CryoTimeoutOn

Off

On

² (Demo
mode: On)

Turns on CryoTimeout on or off. (The property is available only if Cryo is selected on the Options configuration tab page.)

DualOperation

FrontOnly, BackOnly
Shared

Enables the dual-inject mode when set to Shared. In addition, Sharable must be set to On for the single samples (see Practical Tips for Device Control/GC and Temperature  Injecting Two GC Samples Simultaneously (6890)).

EquilibrationTime

0 min

999.99 min in 0.01 increments

² (Demo
mode: 0.5)

After reaching the target temperature, the GC waits for the equilibration time. When the equilibration time has passed, the GC is ready.

(In Demo
mode: Idle)

GC state: Idle, PreRun, Run, or PostRun (read-only).

Sharable

Off, On
