Custom fields 1-10

Custom fields 1-10 may be filled if the data has been acquired with OpenLab CDS ChemStation Edition.

The content of custom fields 1-10 is composed of a label, a separator, and a value.

If you only refer to the field name, the plain content of the custom field is shown. In order to calculate with the content, you must first transform the content to a number using the Val function. RTE automatically creates this expression for you when you add one of the fields.

The following examples show you the results for a sample custom field containing the label TabletWeight and the Value 1020.

Expressions referring to a custom field

Expression	Result
=Sample_CustomField01	TabletWeight|1020
=Trim(Choose(1,Split( Sample_CustomField01 ,"|")))	TabletWeight
=Trim(Choose(2,Split( Sample_CustomField01 ,"|")))	1020 (returned as a string)
=2 * Val(Trim(Choose(2,Split( Sample_CustomField01 ,"|"))))	2040 (calculated number)

If there are more than ten custom fields defined, they are stored in the complex custom fields Sample_CustomFields or Compound_CustomFields. Use the same expression as for complex custom fields to access the values (see Calculate with a complex custom field). You need to know the label of the required custom field.
