100, 400, 1500, 10000ppm: organic farms, restaurants, foot baths. Accurate results in <10 seconds; why wait a minute?
Quaternary ammonium compounds are the most chemically complex sanitizers. Their name derives from the central nitrogen that is bound to four organic groups. Quats bind with microbial cell walls and interfere with their metabolism. They are also shown to be effective against lice eggs and other invertebrates when used in higher concentrations.
Quaternary ammonium chloride solutions come in many varieties. Ours are calibrated for Oasis 146 but can be considered multi quat sanitizer test strips since results for other formulations such as the ones below will still be accurate.
Quats have their advantages & disadvantages:
Note: All test strips Made in USA & are Q/A'd against NIST standards.
Temperature vs ppm results for Hyamine 1622 (Fluka) warmed up from 35 to 60oC (95-140F).
|T (oC)||QAC strips readings at: 0; 50; 100; 200; 400 ppm|
|35||Readings ok for 0-400ppm|
|40||Readings ok for 0-400ppm|
|45||0, 50, 100 ppm readings ok; 200 & 400 ppm read~ 1/2 color square higher|
|50||50, 100 ppm read~ 1/2 color square higher; 200, 400 ppm read 1 color square higher|
|55||Readings 1 color square higher across whole range|
|60||Readings 1 color square higher across whole range|
Follow the directions on the label. All our quat strips are "quick response". In other words, dip the strip & compare to the color chart immediately. If you wait, the color will develop further & give a false high reading.
