Application of multivariate curve resolution alternating least squares (MCR-ALS) to the quantitative analysis of pharmaceutical and agricultural samples.
Application of multivariate curve resolution alternating least squares (MCR-ALS), for the resolution and quantification of different analytes in different type of pharmaceutical and agricultural samples is shown. In particular, MCR-ALS is applied first to the UV spectrophotometric quantitative analysis of mixtures of commercial steroid drugs, and second to the near-infrared (NIR) spectrophotome...
متن کاملIdentification of Reliable Components in Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS): a Data-Driven Approach across Metabolic Processes
There is an increasing need to use multivariate statistical methods for understanding biological functions, identifying the mechanisms of diseases, and exploring biomarkers. In addition to classical analyses such as hierarchical cluster analysis, principal component analysis, and partial least squares discriminant analysis, various multivariate strategies, including independent component analys...
متن کاملSEPARATION OF POLYCYCLIC AROMATIC HYDROCARBONS WITH MIXED MICELLAR HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
Separation of Polycyclic Aromatic Hydrocarbons was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (V/V) as co-organic solvent in mobile phase at 40°C. Analysis of...

متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Biological Samples by Dispersive Liquid-Liquid Microextraction and Gas Chromatography
This work presented determination of some polycyclic aromatic hydrocarbons such as naphthalene, phenanthrene and acenaphthene in biological samples by Dispersive Liquid-Liguid Microextraction (DLLME) and gas chromatography. In this method, the appropriate mixture of extraction solvent (dichloromethane) and disperser solvent (acetone) are injected rapidly into the aqueous sample by syringe. Ther...
