Copper (soluble) Test Kits

Copper (soluble) Test Kits

What is Copper?
Copper (Cu) is a naturally occurring metal in the earth’s crust and in seawater. It can enter water through natural as well as industrial processes. As a highly malleable metal and excellent heat conductor, copper is used in many industrial systems, for example, in piping and heat exchangers. Historically, copper sulfate based algicide or fungicides were commonly applied to ponds and water supplies, however environmental professionals now discourage its indiscriminate use.

Why Test for Copper?
While absorption of a small amount of copper into the human body is necessary to be healthy, too much can cause illness. For drinking water, the Maximum Contaminant Level Goal for copper is 1.3 mg/L. Measuring copper is also useful for monitoring the corrosion of copper pipes. As pipes corrode, more copper will leach into the water. This is a major concern within condensate and heat exchanger systems.

About Our Test Kits
CHEMetrics offers both visual and instrumental test kits for the measurement of soluble copper in drinking water, surface water, groundwater, wastewater, and seawater.

The CHEMets® visual colorimetric test kit turns an orange color in direct proportion to the hexavalent chromium concentration. Measurements are made against a color comparator. Results are expressed as ppm (mg/L) copper.

The Vacu-vials® instrumental colorimetric test kit also turns an orange color and requires the use of a CHEMetrics direct-readout photometer or spectrophotometer capable of accepting a 13-mm diameter round cell.

The Bathocuproine Method

Reference: APHA Standard Methods, 23rd ed., Method 3500-Cu C – 1999.
CHEMetrics’ soluble copper water test kits employ the bathocuproine reagent. Bathocuproine disulfonate forms an orange-colored chelate with copper. The method measures total soluble copper as ppm (mg/L) Cu. The test kits are applicable for analysis of drinking water, surface waters, groundwater, wastewater and seawater.
