::Practical Laboratory Kits.
Ref. DRP-PL1: Ascorbic acid in juice
Ref. DRP-PL2: Uric Acid in urine
Ref.
DRP-PL3: Paracetamol in drugs |
|
|
These kits consist of: Laboratory outlines to carry on an experiment, the analyte (ascorbic acid, uric acid or paracetamol, depending on the test) and the screen-printed electrodes necessary to undertake the practical session.
The experiments have been designed so that they fit in with Analytical Chemistry Courses (clinical, pharmaceutical, industrial and/or food analysis). The kits offer a clear and pedagogic method for learning electrochemical techniques such as cyclic voltammetry (CV), differential pulse voltammetry (DPV), square wave voltammetry (SWV) or amperometric detection (AD), simplifying the preparation of the practical sessions and avoiding problems from working with traditional electrodes (mercury hanging electrode, carbon paste electrodes, etc).
