Determination of micro and macro elements in bottled water by ICP-OES technique
Herman, Vít ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
This Master’s thesis deals with the determination of selected micro and macro elements in bottled water purchased in retail chains Czech Republic. There are described macro elements and micro elements that occur in the waters, bottled waters legislation and the most frequent used instrumental methods for elemental analysis. In this work for the analysis of bottled water were used methods optical emission spectrometry with inductively coupled plasma (ICP-OES) and ion chromatography (IC). Elemental composition of bottled water after analysis corresponded to the composition indicated on the labels, there were recorded only minor deviations from the reported concentrations. All bottled water meets the conditions of the legislation of the Czech Republic. The measured data were statistically processed in the XL Stat program and by multivariate data analysis was examined whether it is possible to individual bottled water from each other based on the analyzes differentiate, which can help in verifying the authenticity of bottled water and in the detection of adulteration of bottled water for profit.

Marketing market research of a selected company
DUSPIVOVÁ, Jitka
The theme of my graduation theses was Marketing market research of a selected company. The firm was manufacturing corporation HBSW Inc. Byňov. The aim of the thesis was take the requirements of consumers and take the market potentials with bottled water. I solved the questions e.g. what influences the end user (for example: price, advertising, flavour, packaging) and farther structure of the end user (form example: age, sex, education, employment). I studied the professional books and the digest of these books is in the second part of my work. The questionary had twenty-three questions. Eight questions appertained to the shopping behavior, ten questions appertained to the consumer behavior, and five questions appertained to the consumer. I used the questions with an opened end and the questions with a closed end. The obtained information was processed in the computer programme MS Excel and Statistica 6.0. I ascertained what new flavours would the consumers like, which flavours are the most popular, how to change the consumption of the packaged water depending on the season. After the data evaluation and data presentation I suggested the solution for the selected company. I believe that this research helps the company HBSW Inc. in the next steps and decision.
