Mikuška, Pavel ; Alexa, Lukáš ; Kouřilová, S. ; Cigánková, Hana ; Křůmal, Kamil ; Itterheimová, Petra ; Kubáň, Petr ; Matoušek, Tomáš ; Barešová, Magdalena ; Pivokonský, Martin
Water from 25 forest springs was characterized for basic physical parameters and chemical and bacteriological composition. Chemical composition was mostly within limits for drinking water, but bacteriological results indicate faecal pollution of water in majority studied springs.

A validation of novel approach for diagnosis of cystic fibrosis (CF) is presented. The method is very simple and fast, since for collection of samples, only wiping of the skin of forearm is needed. The collected sample is analyzed by capillary electrophoresis with contactless conductometric detection (CE-C4D). Ion ratios are determined as ratios of peak area of chloride anion and peak areas of selected cations. It is possible to distinguish between cystic fibrosis patients and healthy individuals when ion ratio is applied as diagnostic factor. In here, we present analytical parameters of developed method (limits of detection, limits of quantification, repeatability of migration times, repeatability of peak areas) and ROC curve, which reveals high sensitivity and specificity of the developed method.
