Integration Delay Delays the start of the timer. Any peak eluting
before the timer starts will not be included in the
peak report.
Filter Level Determines the amount of filtering to apply to the
signal. Filter 1 provides the most filtering.
Column
The Column command allows you to select the column for the next run on
Explorer. The selected column will remain enabled until it is de-selected. This
command over-rides the column sampling sequence on the instrument and forces
the run to be performed on the column selected here. The run will be performed
using the chromatographic settings for the selected column as set by the current
assay.
Start and Stop
The Start command starts a Explorer run. Before beginning a run, ensure Explorer
has been set up correctly. Carrier gas must be supplied to the instrument.
To stop the analysis before it is complete, use the Stop command. If you stopped the
analysis after the sample was injected onto the column you must wait for the
duration of the analysis time for the column to be flushed before beginning another
analysis on the same column. When you stop an analysis,
Explorer will begin to
flush the column and move to the next column.
Calibrate
The Calibrate command calibrates Explorer using the last analysis.
To calibrate the instrument:
1. Perform a run on the first column required by the assay.
The run must include all library compounds specific to the selected column.
Refer to the assay notes supplied with your assay for details.
