How to Create Composite Samples

Modified on: Thu, 6 Aug, 2020 at 5:50 PM

A composite sample can be created under the ECOC TEMPLATES and JOBS tabs. You will see the composite button in the 3rd step of the process, where sample and test information are entered. Once you begin step 3:

  1. Click the "Create Composite" button to create a composite sample relationship tree.

    Definition: The Composite Sample Relationship Tree is marked by the "C" icon and the tree branches. This function is used to indicate the individual samples that make up the composite sample in the first row. Each tree branch is a component of the composite sample (a.k.a. component sample). A composite sample can have one or more components but it must have at least two bottles.
  2. In the first row, you will see a “C” icon to the left. Select an applicable option from the Matrix drop-down in this row. All rows under this grouping will have the same matrix.
  3. Enter each Sample ID, number of bottles and optionally the sampling date and time for the component sample into the subsequent rows. This information will be summarized in the composite sample row.
  4. Select the appropriate tests.
  5. To create a second composite sample, enter your cursor into the blank row outside of the relationship tree. You may repeat the process above or start entering the Sample ID for a regular non-composite sample.

  6. To add a component to a composite sample, enter its Sample ID into the last blank row in the relationship tree.
  7. To remove a component, highlight the desired sample by clicking on the row, and click the red in-line menu on the left to select Disjoin.

  8. Once the sample and test information entries are completed, click “Save & Next” to move to the next step.

Some Useful Tips!

  • The composite Sample ID is not editable and has a limit of 200 characters.  To adjust the composite sample ID, you must make the adjustment on its components.  This function was developed to preserve the relationship of a composite sample set.
  • To avoid unwanted test duplication, identical test selection is prohibited on a composite sample and its components.
