Simultaneous online determination of nitric acid and nitrates in ambient air
Alexa, Lukáš ; Čmelíková, D. ; Cigánková, Hana ; Mikuška, Pavel
The innovated method for the simultaneous online determination of HNO3/NO3- in ambient air was developed. Due to high sensitivity of CLD (LOD = 5.1 nM in water solution, 3 s/n) no preconcentration method is required. The online methods were compared with the results obtained with the offline method based on sampling using filters and dry denuders (DD) covered by 0.5% NaF with subsequent analysis by ion chromatography (model ICS-2100, Dionex, USA) and capillary electrophoresis (model Agilent 7100, Agilent Technologies, USA).

Forest springs, a safe source of drinking water?
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.

Speciační analýzy s využitím generování hydridů
Matoušek, Tomáš
Přednáška prezentovala různé způsoby využití postupu generování hydridů- selektivní generování, postkolonové generování a generování s kryoseparací- v prvkových speciačních analýzách. Příklady z naší laboratoře zahrnovaly aplikace z oblasti klinické analýzy, analýzy potravin a přírodních vod.
