This assignment encourages students to actively engage in the design of analytical instruments by using provided components to assemble devices suited for specific analyses. Tasks include building models for various samples such as fluorescently-stained cells and archaeological materials, while refining skills in analytical chemistry. Students may employ digital tools or traditional methods to visualize the components and their interconnections, fostering creativity and understanding of instrumentation. Emphasis is placed on neatness and proper light paths, promoting an interactive learning experience.

Appendix III Examples of Questions for Students
Question Use the components provided with the assignment to assemble the instruments best suited to the analysis of the following samples: • Fluorescently stained cells • A thin polymer sheet • An acidic sample for trace analysis of Cd • An acidic sample for testing for As, Pb, and Sn • An archaeological sample for elemental analysis Each component provided should be used only once. There are no extra components. Cut each component out and paste them together in the proper arrangement to build each instrument. Arrows should be used to trace the path of light between components. Lines should also be drawn for tubing or gas line connections. This question can be done using PowerPoint, graphics software, or scissors and glue/tape. Marks will be given for neatness.
