Meaning of the Retention Index color coding
> | RI value is greater than average | |
< | RI value is smaller than average | |
≈ | RI value is approximately equal to average *) | |
= | RI value is equal to average | |
? | RI value is unreliable or unrealistic | |
background color of referencing compound |
*) approximately equal to average depends on the column type:
Column type | boundary value | |
---|---|---|
DB-1 | ≤ 5 | |
DB-5 | ≤ 5 | |
DB-17 | ≤ 10 | |
DB-wax | ≤ 20 |
With the average RI value also the number of RI values from which that average is computed is given. E.g. 520 (n=6).
