QuikChek Aerosol Simulants

For chemical and biological bump testing

QuikChek Aerosol Simulants

QuikChek is a non-toxic aerosol simulant used in testing CBRN detection and identification equiment. QuikChek administers a small aerosol challenge to the instrument, allowing the user to qualitatively determine that the equipment is working properly.

With gas detectors, a small pulse of gas is commonly administered to the equipment before it is taken out into the field to see if an upscale reading is obtained. This safety measure is called a “bump test”.

QuikChek can perform both chemical and biological bump tests. It is a medical inhaler that has been charged with a nontoxic pressurized propellant, and in the case of biological bump tests, a small amount of simulant powder. When the inhaler canister base is depressed, a fixed volume of propellant and any suspended aerosol material present is discharged.

The propellant used in our QuikChek aerosol simulants is the same propellant used in most medical inhalers and is of a high purity, with minimal oil and other contaminants. A special high accuracy metered-volume valve is used which provides an output dose that is consistent to within 5% from shot to shot.
