QC Charts tab

The QC Charts tab on the Analyses page shows assay control data for an analysis. Each chart plots one metric for one assay control category. Charts are organized in a grid, with the same metric across each row and the same control type down each column. The x-axis is labeled with the date of analysis and the y-axis depends on the metric.

Toolbar items

• <control filters> — By default, all controls are included. Select another option to filter by a specific control type.

• MS Instrument — The instruments listed vary depending on your organization. Select up to six instruments to aggregate their data.

• Color By — (Available when only one MS instrumented is selected.) Select your preferred coloration for the graphs (e.g., Gradient).

• Start Date — Enter or select the earliest date of data you want to see.

• End Date — Enter or select the latest date of data you want to see

• Control Limits — Select how you want control limits to be defined.

  • Preinstalled — Use the pre-installed control limits.

  • User Defined — Define your own control limits. See Manage user-defined and calculated control limits.

  • Calculated — Calculate control limits from data within one or more date ranges, which you define with the  Calculate button (see below).

•  Limits — (Available when Calculated is selected in the Control Limits list.) Select to view the calculated control limit date ranges. From here, you can also delete a range. See Manage user-defined and calculated control limits.

•  Exclusion — Select to exclude an outlier or other data point from the control limit calculation. Selecting one data point (sample) in a plot excludes the corresponding sample from the other plots. A well containing the mass spec control has 10 reported QC metrics. All other control wells have 11 reported QC metrics. See Manage user-defined and calculated control limits.

•  Calculate — Select to define a calculated control limit based on a range of dates. See Manage user-defined and calculated control limits.

•  Annotate — Select to annotate all control charts for a specific date. See Annotate control charts.
