Many have asked us, how to easily compare compound response across multiple samples.

Here is the answer.

Comparative View allows for a group of samples to be shown side by side with fixed Y-scale to the most intense or a selected threshold reference sample.

The view allows the user to visualize the Expected Retention Time and the Range of Time for peak detection via Markers. This will clearly indicate how the chromatography is responding.

The user can designate samples to be part of individual or multiple groups, by assigning alpha-numeric characters to column in the sample definition screen. Once assigned, and a member of the group is selected in the results grid, the multi-chromatogram pane will display the sample group in columns and the compounds in rows.

The use of a Threshold Sample and a new tab in the method under the Limits section, allows for a visual bar to be set for a specific peak height or a percentage of the Threshold Sample’s peak height.
