Environmental analysis – Water

Regulatory compliance

Numerous standard-compliant methods

Water is our business. Metrohm instruments and applications meet numerous international standards (e.g., ISO, EN, EPA, ASTM, AOAC) for water analysis.

> Have a look at our broad selection of standard-compliant methods!

Chromium(VI): New limit value

New limit value for chromium(VI) in line with EPA 218.7

California imposes a 10 µg/L limit value for chromate in drinking water. You can determine Cr(VI) by ion chromatography according to EPA method 218.7.

Arsenic and mercury in water with the scTRACE Gold

Limit value of 10 μg/L arsenic for drinking water

In addition to arsenic from natural origin, anthropogenic activities contribute to the arsenic contamination of water. The World Health Organization (WHO) recommends a maximum content of 10 µg/L for drinking water.

Arsenic by anodic stripping voltammetry using the scTRACE Gold sensor

Anodic stripping voltammetry (ASV) using the scTRACE Gold offers a straightforward, highly affordable alternative to the spectroscopic determination of arsenic. The method distinguishes between As(total) and As(III). The limit of detection is significantly lower than international limit values.

scTRACE Gold sensor is also suitable for inorganic mercury detection

The scTRACE gold sensor can also determine inorganic mercury in a vast range of water samples. ASV achieves a limit of detection well below the international limit values.

Bromate in water according to EPA 300.1, 317, and 326

Carcinogenic bromate from ozonization

Carcinogenic bromate forms during the ozonization of drinking water. Several international standards stipulate detection limits and test methods.

Great choice of approved detection techniques

Depending on the required detection limit, different detection methods can be used. Conductivity detection with chemical suppression allows the determination of bromate in the lower μg/L range. In the ng/L range, bromate can be detected by IC/MS coupling or post-column derivatization with potassium iodide and subsequent UV detection.

Bromate according to EPA 326.0

Spiked (black) and unspiked (blue) drinking water sample, post-column reaction with UV detection.

Zinc, cadmium, lead, copper, thallium, nickel, and cobalt by voltammetry

Zn, Cd, Pb, Cu, Tl, Ni, and Co must be determined regularly in all types of water samples. Zn, Cd, Pb, Cu, and Tl are determined on the HMDE by anodic stripping voltammetry (ASV), Ni and Co by adsorptive stripping voltammetry (AdSV).

Testimonial: AGQ Labs

"Since we began using Metrohm instruments, we have increased our productivity per sample, in time per sample."

AGQ Labs, an international technological group, applies Metrohm ion chromatographs for environmental water analysis and food analysis.

Testimonial: Iproma

"I trust Metrohm instruments 100%. They help me to make my everyday work easy."

Iproma is an environmental laboratory dedicated to both sampling and analysis of environmental samples, e.g., drinking water, pool water, ground water, or irrigation waters.

Testimonial: AGROLAB

"After 20 years of good experience with Metrohm automated titration, we are most satisfied to have replaced our previous ion chromatography systems for a Metrohm solution, too."

AGROLAB uses Metrohm‘s automatic titration systems for determining the chemical oxygen demand (COD) in wastewater as well as ion chromatography systems for analyzing anions in leachates and wastewater.
