2.1 To make and optimize the design of our innovative 'membraneless collection unit' and test the efficiency (in the term of sensitivity compared to the GD and PV).
2.2 To develop new quantitative methods for the formation of some volatile compounds with new detection system. The methods will be applied to GD and PV techniques for iodine and arsenic determinations.
2.3 To finally apply the method of volatile formation together with the developed detection, to the 'membraneless collection unit'.
