Based on 19 absorption peaks of the subtracted spectra of glucose aqueous solution for de-ionized water, all possible wavenumber combinations were used to establish discrete multiple linear regression (MLR) models respectively, the optimal wavenumbers combination was 3084, 1034, 991 (cm~(-1)), ...
In vivo spectra were collected from the... NS Eikje,T Sota,K Aizawa - Proceedings of SPIE - The International Society for Optical Engineering 被引量: 8发表: 2007年 In vivo interstitial glucose characterization and monitoring in the skin by ATR-FTIR spectroscopy Successful development of real-...
Comparing the reflection measurement results of sugar powder samples (glucose, sucrose) from the FTIR engine and from a stationary spectrometer, we found it was possible to accurately measure even minute peak patterns with the FTIR engine, similar to spectra obtained with the stationary spectrometer....
In addition, the presence of leucocytes, protein, blood, glucose, bilirubin, nitrite, and urine pH being less than 5 or more than 7, were considered abnormal after the urine test result. Spectral data collection All the spectra were collected using a Thermo Scientific Nicolet 6700 FTIR ...
Cross-validation procedures indicated correlations of 0.88, 0.92 and 0.98 for glucose, fructose and sucrose, respectively, between HPLC measured values and FTIR first derivative spectra estimates. Carbohydrates in the expected concentration ranges were found for most of the pure fruit labelled juices. ...

The model has been established from a correlation between the α-glucosidase inhibitory activity and FTIR spectra of P. macrocarpa. To the best of our knowledge, this is the first attempt to develop a rapid predictive model by fingerprinting the compositions of this plant under different solvent ...
2. Department of Biological Engineering,Jinan University,Guangzhou 510632,China) Abstract: By using Fourier transform infrared spectroscopy (FTIR)and attenuated total reflection (ATR)technology,the analysis models for glucose aqueous solution was established. Based on the subtracted spectra of glucose ...
