A Soft Thresholding Wavelet-based Radial Basis Function Neural network (STWRBFN) method was developed to perform simultaneous quantitative analysis of multicomponent mixtures.
A wavelet soft thresholding kernel partial least squares (WSTKPLS) method was developed to perform simultaneous quantitative analysis of the mixture of o-dihydroxybenzene, m-dihydroxybenzene, p-dihydroxybenzene and phenol with overlapping spectra.
Simultaneous Quantitative Analysis of Mixture of Four Components with Overlapping Spectra by Wavelet Soft Thresholding Kernel Partial Least Squares Method
The calibration model for simultaneous determination of glucose,fructose and sucrose in aqueous solution was built by partial least squares and short-wavelength near infrared spectroscopy(800-1 100 nm).
A simple high performance liquid chromatographic assay for the simultaneous quantitative analysis of seven ginsenosides, Rb1, Rb2, Rc, Rd, Re, Rf and Rg1 in commercial ginseng products is described.
This paper discusses a rapid GC-FID technique for the simultaneous quantitative analysis of FFA, MAG, DAG, TAG, sterols, and squalene in vegetable oils, with special reference to palm oil.
The determination of methanol and fu-sel oil in potable spirits was accomplished byusing GDX-102 modified with 5% of poly-ethylene glycol(PEG-20M) as gas chromato-graphic stationary phase. By direct injectionquantitative measurements of 16 componentsin potable spirits could be made, they weremethanol, propanol, sec.-butanol, isobu-tanol, butanol, sec. -pentanol, isopentanol,pentanol, hexanol, ethyl acetate, ethylbutyrate ethyl Valerate, ethyl lactate, ethylcaproate, acetaldehyde and furfural. Thedeterminati...
The multicomponent analysis using Kalman Filtering method with the DMS 200 UV/VIS spectrophotometer-IBM PC/AT on-line system is described.The collecting of analytical data, converting of spectral files and processing of the Kalman Filtering were realized automatically.Satisfactory results were obtained for the simultaneous determination of dibutyl phthalate(DBP), potassium hydrogenphthalate(PHP), and methyl sa icylate(MSA).
The cuticle and its substructure,types,proportions and arrangementsof cortex,sizes and ultrastructures of cortical cells in lnner Mongolian Alpasand Liaoning×Inner Mongolian cross white cashmere fibers were studiedunder TEM and Light microscope,Relationships between cortical diameterand cortex arrangement,between cortical diameter and cross-section areaof cortical cell,between ultrastructure and associated textile/physical-chemi-cal properties were also investigated.
