About us
Hanby colorimetric test method was discovered in 1986 by John Hanby for identifying the presence of hydrocarbons in soil or water. The Hanby method offers a revolutionary solution to obtaining on-site samples that potentially contain petroleum related substances. Field testing is inherently costly, time consuming and, quite often, unreliable. The Hanby method is designed to provide a precise color indication of the concentration of petroleum (gasoline, diesel, crude oil, etc) in field samples. This rapid, accurate method won immediate recognition by the United States Environmental Protection Agency, state regulatory agencies throughout the United States and various international regulatory agencies around the world.
