Based on the Gutzeit method, the testing kit produces a coloured strip in order to detect and visually measure soluble inorganic arsenic (As+3 and As+5).
Kit has a detection range up to 500 ppb, with the following measuring range (colour scale graduation): 0-5-10-20-30-40-50-60-80-100-150-200-250-300-400-500 ppb As+3/+5
Results are available in less than 20min, including sample preparation and necessary reaction time.
The kit includes three (3) different powdered reagents with two (2) reaction vessels, colour chart bottle label and has enough test strips and reagent to conduct 100 tests. Kit comes in a sturdy plastic case.
