Introduction
The general idea of both editions of AnalChemVoc project was to bring affordable, simple and robust analytical instruments to vocational schools (as well as other secondary schools), together with ample selection of educational activities supporting the equipment. The spectrometer SpektraTM, developed by one of the participants of the project (Gros, 2004; Gros & Vrtačnik M, 2005), was particularly well described with this respect.
However, the use of simplified analytical instruments imposes also certain limitations to the concepts that could be studied during the course of analytical chemistry. Therefore in this edition (second) of AnalChemVoc we tried a new approach: apart from bringing simplified instruments to schools, let us bring school students to the modern, state-of-the-art, sophisticated instruments placed in the university research laboratories. Within this concept, several analytical procedures were developed, based on the following propositions:
- students are introduced to a specified concept of analytical chemistry
- students collect the samples for analysis by themselves (food, everyday use preparations, environmental samples)
- students prepare the samples in the school laboratory in form suitable for measurements on research instruments, such as professional HPLC or microtitrator
- on their visit at the university laboratories, students make the measurements with the help of qualified university personnel
- they work on the collected data at school under the supervision of their teacher, developing a specified concept of analytical chemistry
In this section several activities, developed according to this approach, are presented.
