Sample Sequence

The sample sequence (also called Sequence Table) defines the vials to apply for the method/analysis. Each application is identified by a track number (field Tr.). Depending on the plate layout parameters, the track number gives a position on the plate. It’s possible to leave some tracks empty (for example, track 4 in the next capture), and to perform multiple applications on the same track (for example, track 2 in the next capture). In this last case, the overspotted tracks are identified with a + sign. In analysis files, the Vial ID/volume of each application is required, and in case of an application using the ATS4 instrument, the rack position is required too.

Note

Since visionCATS 2.1, Sentence case (first letter in upper case) is used for vial and substance names, to avoid any duplicates because of different case.

Even after importing from another system, a vial or a substance should be unique. Sentence case enforcement implies that regardless of who and where it was entered, it would always be displayed the same, on every visionCATS system.

Each track of the sample sequence is either defined as Reference or Sample. This setting documents the role of each track and, in the whole Evaluation part, has a major influence because it determines the tracks used to compute the calibration function and the tracks used to compute the results of the evaluation.

An additional SST check box is used to define the SST tracks. See System Suitability Testing (SST) for more details.
