Description

AnticipatedColdTrapStart

Anticipated sync before incubation end

0-15.0 min

When the remaining incubation time falls below the specified value, the sampler sends a trigger signal to the GC to start the cold trap.

GCCycleTime

Analysis Time

0-600.0 min

Sets the GC cycle time, i.e., the time between two injections. Enter the minimum time that the GC requires after an injection to be ready for the next sample. The following conditions must be met:

GCCycleTime > PGM run time.

The following is recommended:

GCCycleTime > PGM run time + 1 min.

Tip:

The GCCycleTime should be long enough to allow the GC to cool down and equilibrate.

IncubationTime

0-600.0 min

Sets the oven incubation time for the sample (in Single and MHE mode) and the incubation time for the first sample of a sequence (in Progressive mode).

IncubTimeOffset

Progressive Incubation Time

0-600.0 min

Increases the IncubationTime by that many minutes for the second sample and each subsequent sample (Progressive mode only).

PreparationTime

0-600.0 min

Reports the remaining incubation time for the sample to be injected next (read-only). The PreparationTime data is logged to the Audit trail during each inject procedure and can later be inserted in the report.

RealIncubationTime

0-600.0 min

Reports the incubation time for the current sample (read-only). This parameter corresponds to the IncubationTime property in Single and MHE injection mode. In Progressive mode, the value is calculated using the parameters IncubationTime, IncubTimeOffset, and the sample number. The value is logged into the Audit Trail at inject time.

VentingTime

Multiple Extraction Venting Time

0-60s

Specifies for how long the vial is being  vented after each injection to remove the headspace gas (MHE mode only).

Thermo Scientific

Range/Values

Description

ShakerOnTime*

Agitator On

0-600s , Off

Turns the shaker on for the specified time or turns it off (Off).

ShakerOffTime*

Agitator Off

0-600s

Specifies for how long the shaker is off during an agitation cycle.

If ShakerOffTime = 0, the shaker runs continuously.

Thermo Scientific

Range/Values

Description

DownSpeed

Needle Speed in Vial

0-250 mm/s

Specifies the speed at which the needle moves down into the vial.

DrawSpeed

Filling Speed

1-100 ml/min

Sets the speed of the syringe plunger during sample load and for the preparing fill strokes.

ErrorModeMissingVial

AbortBatch,

Continue

Determines the behaviour of the sampler in case a 'missing vial' error occurs. The following conditions are possible:

The sampler terminates the batch run immediately (AbortBatch), or the sampler continues the batch run (Continue) and performs a dummy injection with air.

FillStrokes

Filling Count

0-15

Sets the number of the preparing fill strokes.

FillVolume

Filling Volume

0-4.5 ml

Specifies the volume that the sampler draws for the preparing fill strokes.

InjectDepth

10-35 mm

Sets how deep the needle moves into the GC inlet.

InjectSpeed

1-100 ml/min

Determines how fast the sample is injected into the GC inlet.

PostInjDelayTime

Post-Injection Delay

0-60s

Specifies for how long the syringe remains in the injector after the injection.

PostInjFlushTime

Post Injection Syringe Flush

10-599, Infinite

Sets the time the syringe is flushed after injection. Select Infinite to flush the syringe during the entire analysis.

PreFill

Enable Pre Filling

On, Off

Set to On to enable pressurization before sampling the headspace vapor. The volume used to pressurize the vial is identical to the sample per load.

PreInjDelayTime

Pre-Injection Delay

0-60s

Specifies the delay the syringe remains in the injector before the injection.

PreInjSyringeFlush

On, Off

When set to On, the syringe is flushed for 5 seconds before the injection.

PullupDelay

Filling Delay

0-60s

Sets the delay between drawing the sample into the syringe and dispensing the volume into the vial during a preparing fill stroke cycle.

SampleDepth

Sample Vial Depth

10-40 mm

Specifies how deep the needle descends into the vial during the preparing strokes and sample load.

StandbySyringeFlush

On, Off

When set to On, the syringe is flushed continuously while the sampler is in standby mode.

Command/Property

Description

DryTime

0-60s

Sets the time the sampler remains idle after a washing procedure to allow the needle to dry.

WashFrenquency

Never, EverySample,

After2Samples, After5Samples, After10Samples, After25Samples, After50Samples

Specifies after how many sample injections a washing procedure is started during a sequence run.

Note:  

To calculate WashFrequency, the sampler takes its internal sampler sequences into account (not the Chromeleon sequences as displayed in the sample list). The actual wash procedure may therefore not comply with the defined setting, if either of the following situations occur:

• when a Chromeleon sequence is split into several sampler sequences

• the sampler runs in MHE mode
