Journal Highlight: Digital bandstop filtering in the quantitative analysis of glucose from near‐infrared and midinfrared spectra

Date: Jan 20, 2020

Author: spectroscopyNOW

Bandstop filtering has been proposed as a pretreatment method in the quantitative analysis of glucose from both near-IR and mid-IR spectra, comparing with traditional bandpass filtering and implementing with principal component regression and partial least squares regression.
