Abstract EN
A multichannel short-wave near-infrared (SW-NIR) spectrometer module based on charge-coupled device (CCD) detection was designed.
The design relied on a tungsten lamp enhanced by light emitting diodes, a fixed grating monochromator and a linear CCD array.
The main advantages were high optical resolution and an optimized signal-to-noise ratio (0.24 nm and 500, resp.) in the whole wavelength range of 650 to 1100 nm.
An application to alcohol determination using partial least squares calibration and the temperature correction was presented.
It was found that the direct transfer method had significant systematic prediction errors due to temperature effect.
Generalized least squares weighting (GLSW) method was utilized for temperature correction.
After recalibration, the RMSEP found for the 25°C model was 0.53% v/v and errors of the same order of magnitude were obtained at other temperatures (15, 35 and 40°C).
And an r2 better than 0.99 was achieved for each validation set.
The possibility and accuracy of using the miniature SW-NIR spectrometer and GLSW transfer calibration method for alcohol determination at different temperatures were proven.
And the analysis procedure was simple and fast, allowing a strict control of alcohol content in the wine industry.
