1. A method, comprising:
receiving, by a control device, information associated with a first spectroscopic model that is generated based on a master data set from a first spectrometer;
causing, by the control device, a second spectrometer to perform one or more spectroscopic measurements based on receiving the information associated with the first spectroscopic model;
receiving, by the control device and from the second spectrometer, the one or more spectroscopic measurements as a target data set;
generating, by the control device and using cross-validation, a second spectroscopic model based on the target data set; and
performing, by the control device, a spectroscopic analysis using the second spectroscopic model.
