Method 7C and 7D
Method 7C and 7D
In Method 7C and 7D a sample is passed through a series of special, full-size orifice impingers that contain an alkaline-potassium permanganate solution. The sample rate is between 400 and 500 cc per minute, normally three one hour samples are collected per test. The XC-623 is the console of choice, however, a low-flow orifice adapter is offered for converting the XC-572 Method 5 source sampler console for low-flow sampling. The sample is analyzed colorimetrically for Method 7C and by ion chromatography for Method 7D.
