Opa ortho phthalaldehyde
WebOPA test strips are chemical indicators to determine whether the concentration of ortho-phthalaldehyde, is above or below the established minimum effective concentration (MEC) of 0.3%. It is recommended that the disinfectant be tested before each disinfection cycle to ensure that the ortho-phthalaldehyde is above the MEC. WebThe reaction of ortho-phthalaldehyde (OPA) with amino acids and proteins was investigated as a possible mode of action. Bacterial pellets (obtained by centrifugation) changed colour after exposure to OPA. These colours were more intense at alkaline than acidic pH. Acidic and alkaline OPA reacted with primary amino acids to form coloured …
