Preparation of flaxseed for lignan determination by gas chromatography–mass spectrometry method
defatting extraction GC/MS hydrolysis lignans
2014/2/25
Since 1980s, several methods for the determination of lignans in food samples have been developed depending on the types of lignans and foods analysed, but mostly on flaxseed as a reference food. In t...
Determination of fluoride in plant material using microwave induced oxygen combustion
ion-selective electrode sample preparation tea
2014/2/25
Fluorine is essential in human and/or animal nutrition, thus it is important to know its concentration in a diet. One of the important sources of fluorine for humans is tea, containing relatively high...
