About Quaternary Ammonium or "quats"

In some food processing plants, ""quats"" are used to sanitize equipment prior to long periods when the equipment will not be used. The "quats" are generally effective at killing vegetative yeast and mold cells. They are less effective at killing bacterial endospores and fungal spores.

Activity of the "quats" against bacteria varies greatly, depending on the type of bacteria. Typical quat concentrations used for food contact surfaces are 200 - 400 ppm, with a follow-up running water rinse usually done prior to the next use of the equipment.

For certain "quats" and concentrations, a post-use rinse is required by regulations. The "quats" work over a wide pH range, with best activity in alkaline pH (click here to see our simple pH testing strips). Hard water will diminish the effectiveness of "quats", as will residues of food or cationic surfactants.

Mid Range QT-40 Test Kit

The mid-range test kit is the best compromise and is favored by many of our regular customers who are professionals in the field of sanitation. There is more resolution of concentrations on the scale, and the somewhat higher range allows more reading scope.

Mid Range QT-40 test kits are supplied in packages of 5 rolls per shipment/order. There is no "refill" available.

High Range Test Kit

When hard water or other conditions compromise the effectiveness of a normal quat treatment, higher concentrations are called for--concentrations that may be required to exceed the normal range of our testing strips. In these circumstances, use our High Range (0-1000 ppm) test strips (see ordering details at left).

If you are uncertain, start with the High Range version of the test--this will cover all concentrations that would reasonably be used for this sanitizing operation.

If you are using hard water for sanitizing rinse applications, generally the reading should be above 400 ppm for sanitizing effectiveness.

High Range Kit Contains:

five (5) 15' rolls
five (5) dispensers with color match charts
Range 0-1000 ppm

Refill package does not include dispensers and only has on color match chart included in the bulk 5-roll case.
