BASIC FIA (FLOW INJECTION ANALYSIS) LAB

This excercise demonstrate something of the versatility and the speed of flow analysis techniques with modern and flexible equipment. Spectrophotometric detection of copper with simple reaction is used as a model reaction (the formation of Cu-NH3 complex which has a strong blue color)

START

DETECTION OF NITRITES AND NITRATES LAB

Numerous analytical methods exist and the reduction of nitrate to nitrite for quantitative colorimetry has proven to be both sensitive and very reliable for flow injection analysis. A copperized cadmium column is used to catalyze the reduction of nitrates into nitrites in a reproducible and quantitative fashion. Nitrites will react with sulfanilamide to form azo dyes that will then couple with N-(1-Naphthyl) ethylenediamine dihydrochloride to form magenta colored solution.

CALCIUM ION SELECTIVE ELECTRODE

Virtual lab with new design and engineering solutions. Goal of the laboration is to illustrate one of many calcium concentration detection techniques. Ca-ion selective electrode gives voltage when it is submerged in Ca2+ solution, the voltage is proportional to the ion concentration.

SYSTEM REQUIREMENTS

VIRTUAL LABS have been tested on both Microsoft Windows XP and Mac OSX 10. Choice of web browser is not important as long the browser supports Macromedia Flash. To experience VIRTUAL LABS at full the user should have Macromedia Flash Player version 6 or later. Macromedia Flash plug in (player) is installed automatically then the lab is run for the first time. New version of the player can be installed from http://www.macromedia.com
