Rapid Determination of Protein Contents in Microencapsulated Fish Oil Supplements by ATR-FTIR Spectroscopy and Partial Least Square Regression (PLSR) Analysis

Food and Bioprocess Technology, 2013
Following the recent success in quantitative analysis of essential fatty acid compositions in a commercial microencapsulated fish oil (μEFO) supplement, we extended the application of portable attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopic technique and partial least square regression (PLSR) analysis for rapid ...

Simultaneous Determination of Pentaerythritol Tetranitrate and 2,4,6‐Trinitrotoluene by High Performance Thin Layer Chromatography and Partial Least Squares Regression (PLSR) Method

Propellants, Explosives, Pyrotechnics, 2010
AbstractHigh performance thin layer chromatography (HPTLC) has been used for the simultaneous determination of pentaerythritol tetranitrate (PETN) and 2,4,6‐trinitrotoluene (TNT). With this aim, the spots were developed on silica gel 60 F254 layers with petroleum ether–acetone (2 : 1 v/v).

Rapid determination of biomass and polypropylene in three types of wood plastic composites (WPCs) using FTIR spectroscopy and partial least squares regression (PLSR)

Holzforschung, 2014
Abstract The biomass/plastic ratio in wood plastic composites (WPCs) has been evaluated because of the great practical importance of this topic. To this purpose, FTIR spectra of 59 polypropylene (PP)-based WPCs from three biomass species (Chinese fir, poplar, and bamboo) were recorded and the spectral dates were evaluated by means of the

Assessing lignin content in Nordic hardwood and softwood species using models based on near-infrared (NIR) spectral data and partial least squares regression (PLSR)

TAPPI Journal
Continuous kraft cooking digesters face challenges affecting product quality, making it valuable to improve control through advanced techniques like near-infrared (NIR) spectroscopy, model predictive control, and machine learning models. The primary goal of this study was to use NIR spectra to predict the amount of lignin in hardwood and softwood ...

Stress-Testing Partial Least Squared Regression (PLSR) Models via Generative Spectral Perturbation: A Demonstration in NIR Pharmaceutical Analysis

Partial least squares (PLS) regression coupled with near-infrared (NIR) spectroscopy is central to real-time pharmaceutical quality monitoring under the Process Analytical Technology (PAT) framework. While Hotelling T² and Q residuals are routinely used to monitor deployed models, the spectral regions and perturbation types that drive exceedances in ...
