To do this, a scale, or calibration curve, must be constructed using several known concentrations for each compound of interest.

Using multiple standards, a calibration curve of time versus molar mass can be developed.

For the most accurate work, variations are compensated by means of calibration curves.

If the calibration curve is 'wiggly', there will be multiple ranges.

Overlap of calibration curves should be minimal to yield the most statistically powerful results possible.

Dozens of ampules were thus sent back at various thrust levels and a calibration curve set up.

I have seen the calibration curve without understanding the purpose at the time.

Second, the calibration curve provides data on an empirical relationship.

Among others, all the tree ring samples used for the calibration curves (see below) were determined by these counting techniques.

For others a calibration curve or equation is required.
