1. A method, comprising:
identifying, by a device, a pseudo steady state end point based on spectroscopic data,
the pseudo steady state end point indicating an end of a pseudo steady state associated with a blending process;
identifying, by the device, one or more of a reference block or a test block from the spectroscopic data based on the pseudo steady state end point; and
generating, by the device, one or more of a raw detection signal associated with the reference block or a raw detection signal associated with the test block.
