The CHEMets Method
To perform a test, immerse the CHEMet 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). For higher concentrations, the flat comparator is used. For lower concentrations, the round comparator is used. The ampoule is compared with the standards until a color match is found.

Kits include 30 ampoules, comparator(s), accessory solution(s)(when necessary), a sample cup, and instructions. Refill packs of 30 ampoules and accessory solutions are available separately. Comparators have a 2-year shelflife. Material Safety Data Sheets are provided in test kits.

CHEMets ampoules are designed for maximum simplicity and accuracy. Each glass ampoule is 7 mm in diameter, 100 mm in length, with a tapered, pre-scored tip; reagents are vacuum-sealed inside.

The Maximum Contaminant Level Goal for copper is 1.3 mg/L in drinking water.

The measurement of copper is an important means of monitoring the corrosion of condensate systems and heat exchangers.

CHEMetrics' test kits employ the bathocuproine reagent.

Bathocuproine disulfonate forms an orangecolored chelate with copper. The method measures total soluble copper as ppm (mg/L) Cu.
