Abstract
The invention describes a composition useful in determining sample analytes, where the determination is carried out anaerobically. The compositions include an analyte oxidizing agent, an electron transfer agent, ferric ions, and two chelators. The first chelator complexes to ferric ions, but does not have good affinity for ferrous ions. The second chelator does chelate ferrous ions, and forms a colored complex with the ion. It is the colored complex which serves as the indicator for the analyte. Different formulations of the composition are described.
