UV-method for the determination of Aspartame (and breakdown
products) in foodstuffs, beverages and other materials

Principle:
                       (pH 12.5)
(1) Asp-Phe-O-Me → Asp-Phe + MeOH

                      (dipeptidase M)
(2) Asp-Phe + H2O → L-aspartate + L-phenylalanine

                      (glutamate-oxaloacetate transaminase)
(3) L-Aspartate + 2-oxoglutarate → L-glutamate + oxaloacetate

                                 (L-malate dehydrogenase)
(4) Oxaloacetate + NADH + H+ → L-malate + NAD+

Kit size:                            * 50 assays (manual) / 500 (microplate)
                                          / 500 (auto-analyser)

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM 
Wave
