Abstract
A system including a first container, wherein the first container includes a sample. The system includes a second container, wherein the second container comprises a reagent. Additionally, the system includes a test cell, wherein the test cell is configured to receive the sample and the reagent. Further, the reagent includes at least one of Griess reagent, sulfanilamide, or 1,5-diphenylcarbazide. Moreover, the test cell is situated in a chamber, wherein internal walls of the chamber are white.
Claims20
A method comprising:
- mixing a sample with a reagent, wherein the reagent comprises at least one of Griess reagent, sulfanilamide, or 1,5-diphenylcarbazide;
- taking an image, using a camera, of the mixture of the sample with the reagent;
- and
- analyzing the image.

A method comprising:
- mixing a sample with a reagent, wherein the reagent comprises at least one of Griess reagent, sulfanilamide, or 1,5-diphenylcarbazide, wherein the sample comprises at least one of nitrite, Chromium (VI), or hexavalent Chromium;
- taking an image, using a camera, of the mixture of the sample with the reagent, wherein the camera is incorporated in a device, wherein the device is a cell-phone, wherein the camera is a 12 megapixel camera;
- and
- analyzing the image, wherein the analyzing the image comprises analyzing the hue, saturation, and value (HSV) of the image.
1 more element
A system comprising:
- a first container, wherein the first container comprises a sample, wherein the sample comprises at least one of nitrite, Chromium (VI), or hexavalent Chromium;
