To perform a test, immerse the CHEMets ampoule into the sample and snap off the tip (Step 1).  The correct volume of sample is automatically drawn in, filling the ampoule; a small inert gas bubble remains in the ampoule. To facilitate mixing the sample and reagent, tilt the ampoule back and forth so the bubble travels from end to end (Step 2). In 2 minutes or less, quantify the result by comparing the filled ampoule to the appropriate color standard(s) (Step 3).

The VACUettes® Auto Dilution Method: Hold the ampoule in a horizontal position while the capillary tip contacts the sample (Step 1). After the capillary fills, immerse it in a diluent (usually deionized water); snap the tip off the ampoule (Step 2). The sample and diluent are drawn into the ampoule where they mix with the reagent (Step 3). The resulting color.

The Vacu-vials® Method: To perform a test, immerse the Vacu-vials ampoule into the sample and snap off the tip (Step 1).  The correct volume of sample is automatically drawn in, filling the ampoule; a small inert gas bubble remains in the ampoule. To facilitate mixing the sample and reagent, tilt the ampoule back and forth so the bubble travels from end to end (Step 2). In 2 minutes or less, quantify the result by placing the filled ampoule in the cell holder of an instrument set to a wavelength for optimal absorbance (Step 3).
