AFTE Store - Quantofix Nitrite Sheet Validation for Use Within the Modified Griess Test: A Technical Report

Several problems exist with the currently employed Modified Griess Test, including: The limited availability of glossy photographic paper, the ever-changing chemistry of the emulsion layer on inkjet photo paper, the preparation time required to treat the paper(s), and the exposure to the chemicals necessary to prepare the paper(s). A solution to each of these
problems appears to exist in a new product for the detection of nitrites: a pre-treated, ready-to-use paper called Quantofix Nitrite Sheets. These sheets of testing paper, as well as conventional Modified Griess pretreated inkjet photo paper were tested side-by-side in order to validate Quantofix Nitrite Sheets for use within the Modified Griess test. Side-by side testing found the Quantofix Nitrite Sheets to have comparable, if not superior, chromophoric results to that of the currently used treated inkjet photo paper.
