The use of near-infrared spectroscopy for characterisation of raw material for sunflower oil production
Vystavělová, Petra ; Vránová, Dana (referee) ; Pudilová, Ludmila (advisor)
This diploma thesis provides summary information about using of near infrared spectroscopy for monitoring of high oleic acid content in sunflower seed. The calibration for high oleic sunflower seed was performed by using calibration model PLS - „Partial least squares. Gas chromatography was used as a reference method. Based on this knowledge thirty samples of high oleic sunflower seeds were measured and evaluated on this calibration. The last part of diploma thesis consist of comparison of oleic acid results measured by near infrared spectroscopy and gas chromatography used as reference method, and discussion about the measurement accuracy and evaluation of suitability of using these methods.

Biological analysis in NIR
Vašík, Lukáš ; Ronzhina, Marina (referee) ; Čmiel, Vratislav (advisor)
The purpose of this semester work is to obtain information about analyzes by IR radiation. It focuses mainly on optical analyzes in the near IR region. The theoretical part deals with the influence of IR radiation on substances and the principles of functions of IR spectrometers.

Biological analysis in NIR
Pirkl, Petr ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This bachelor thesis is focused on obtaining information about analyzes by IR radiation. It also deals with the effect of IR radiation on substances and the principles of functioning of IR spectrometers. There are examined coffee samples in the work. Usefulness for discrimination caffeine and decaffeinated coffee is tested. Next, flour samples are researched. There is examination of presence or absence of gluten.
