Look Ahead
Look Ahead can be set in the Advanced section on the Instrument tab of the Scan and
Instrument Setup dialog.
What is Look Ahead?
Look Ahead is a novel system where the spectrometer scans continuously and uses the
properties of the measured spectrum to identify changes corresponding to sample
removal, sample insertion, or sample change, automatically.
This information is used to identify the scans that are being collected, and to accumulate
sample scans. This can decrease the overall scanning time required for those samples
that require scan accumulation.
What does Look Ahead do?
If Look Ahead has been enabled, the spectrometer scans continuously. When you
request a sample scan, the scan collected is compared to the scans that have already
been collected. If identical scans are found, the number of scans requested is decreased
by the number of scans found, so decreasing the overall scanning time.
