Output grid

The output grid page shows a summary of all the assay data you have entered. Normally assay data is entered in several different grids to help organise it. The output grid combines each different page of assay data into a single non-editable table for quick reference.

Tip: When selecting a measurement in the output grid and opening the context menu, the option Go To Measurement opens the measurement grid containing the assay measurement at the location of the measurement.

Filter values in the output grid

By default the output grid combines all the data which may have been entered in several different measurement grids. You can filter the type of data displayed in the output grid using the Format menu in the top right corner of the grid. The Format menu allows you to select from several different types of measurement data. Normally the output grid only displays assay measurements in each category when you have actually entered data for a particular property. For example, in the Fundamental Properties category, if you had only entered density measurements only density would be shown. Other fundamental properties, such as yield, would not be shown. However for distillation properties the output grid shows the properties and values even if no data is included. For example, for the 9-point D86 property the boiling point profile of each cut is shown, even if no data was included for distillation in the measurement grid.

Compatibility (gravimetric)

The Compatibility (gravimetric) is used to enter compatibility data for crudes. This grid should be used for crudes which are not waxy. For waxy crudes the alternative UV grid should be used ().

For normal crudes compatibility data is entered as the percent asphaltenes insolubles. The percent insolubles is measured using one of two solvents:

• n-heptane (C7)

• n-pentane (C5)

The solvent used for the particular analysis can be set using the drop-down menu in the Compatibility grid.

Compatibility (waxy crude)

The Compatibility (UV) is used to enter compatibility data for waxy crudes. This grid should be used for crudes which are considered waxy. For non-waxy crudes the alternative gravimetric grid should be used (Output grid).

For waxy crudes compatibility data can be entered from two test methods:

• Wax + Asph Insolubles

• UV Asph Insolubles

The insolubles can be measured using one of two solvents which is selected using the drop-down menu at the top of the Compatibility grid:

• n-heptane (C7)

• n-pentane (C5)
