What can interfere with the QuanTab® Test Strips for chloride?
Choride test strip inteferences
The QuanTab® Test Strip reaction involves the formation of silver chloride on the strip from the combination of silver on the strip with chloride in the sample. Any anion (for example bromide, iodide, cyanide, and sulfide) which will react with the silver to give an insoluble precipitate may interfere with the Quantab® test and give a higher than actual result. Strong acids may also interfere, however the strips will work in caustic or extremely high pH samples. Nitrite and nitrate have no adverse effect on the Quantab® test. QuanTab® test strips will work in colored solutions as long as they are clear, however turbid solutions can clog the wick and cause very slow or incomplete reactions. Filter turbid samples before testing. QuanTab® strips can be used in a wide range of temperatures.
