Predictive equations were determined for the calibration set of samples by regression of 800 area (x-variable) and gravimetric mass (y-variable). Equations were then used to predict gravimetric mass in the test set of samples, based on the 800 area response. Predicted gravimetric mass was compared to measured gravimetric mass via linear regression.

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...
