A new strategy for quantitative analysis of a major clinical biochemical indicator called glycated hemoglobin (HbA1c) was proposed. The technique was based on the simultaneous near-infrared (NIR) spectral determination of hemoglobin (Hb) and absolute HbA1c content (Hb HbA1c) in human hemolysate samples. Wavelength selections were accomplished using the improved moving window partial least square (MWPLS) method for stability. Each model was established using an approach based on randomness, similarity, and stability to obtain objective, stable, and practical models. The optimal wavebands obtained using MWPLS were 958 to 1036 nm for Hb and 1492 to 1858 nm for Hb HbA1c, which were within the NIR overtone region. The validation root mean square error and validation correlation coe±cients of prediction (V -SEP, V -R P ) were 3.4 g L À1 and 0.967 for Hb, respectively, whereas the corresponding values for Hb HbA1c were 0.63 g L À1 and 0.913. The corresponding V -SEP and V -R P were 0.40% and 0.829 for the relative percentage of HbA1c. The experimental results con¯rm the feasibility for the quanti¯cation of HbA1c based on simultaneous NIR spectroscopic analyses of Hb and Hb HbA1c.

“…NIR spectra were collected over a range of 960-1690 nm with the interval of 6 nm, The instrumentation was calibrated by using modified partial least squares (MPLS). In addition, calibration models for determination of dry mater, starch content, in vitro digestibility by cellulase, and soluble sugars in maize forage based on NIR measurements taken directly on the chopper during harvest were developed (Welle et al, 2003). Using a network of six diode arrays, NIR spectrometers were implemented successfully for on-line analysis of dry matter corn grain (Welle et al, 2005).…”

“…Given that NIR absorption strength is weak, most sample types can be measured directly without preprocessing and reagents. The NIR spectroscopic analysis is a rapid and reagentless technique that has been proven to be a powerful analytical tool for use in agriculture, [9][10][11][12][13] food, 14,15 environment, 16,17 medicine, 18,19 pharmaceuticals, 20 and so on. However, to the best of our knowledge, a quanti¯cation method for TCP using NIR spectroscopy has not been developed yet.…”

Teicoplanin (TCP) is an important lipoglycopeptide antibiotic produced by fermenting Actinoplanes teichomyceticus. The change in TCP concentration is important to measure in the fermentation process. In this study, a reagent-free and rapid quanti¯cation method for TCP in the TCP-Tris-HCl mixture samples was developed using near-infrared (NIR) spectroscopy by focusing our attention on the fermentation process for TCP. The absorbance optimization (AO) partial least squares (PLS) was proposed and integrated with the moving window (MW) PLS, which is called AO-MW-PLS method, to select appropriate wavebands. A model set that includes various wavebands that were equivalent to the optimal AO-MW-PLS waveband was proposed based on statistical considerations. The public region of all equivalent wavebands was just one of the equivalent wavebands. The obtained public regions were 1540-1868 nm for TCP and 1114-1310 nm for Tris. The root-mean-square error and correlation coe±cient for leave-oneout cross validation were 0.046 mg mL À1 and 0.9998 mg mL À1 for TCP, and 0.235 mg mL À1 and 0.9986 mg mL À1 for Tris, respectively. All the models achieved highly accurate prediction e®ects, and the selected wavebands provided valuable references for designing specialized spectrometers. This study provided a valuable reference for further application of the proposed methods to TCP fermentation broth and to other spectroscopic analysis¯elds.
