The analysis of air, water and soil has become of essential importance in many industries.

Metrohm provides a significant range of scientific instruments and applications designed especially for environmental monitoring. Manufactured by the most renowned companies in their field, the instruments are not only sold and serviced by Metrohm but customers in Australia and New Zealand can tap into the vast knowledge and experience of the world’s leading scientists using Metrohm’s on location support and service.

Simultaneous online monitoring of water hardness (Ca2+ and Mg2+)

Online hardness analysers are commonly used to monitor brine solutions and various water processes (e.g. drinking water). Hardness can be measured using a titration or a photometric method. With the titration method both calcium and magnesium hardness can be measured separately.

Sulphur speciation in mining leachates by ion exchange with direct UV detection

In exception of sulphate, most of the sulphur species can be determined by direct UV detection at about 215 nM. Health and safety pressures is motivating the gold mining industry to develop a substitute to cyanide for leaching processes. The drive is mainly based on the high toxicity of cyanide....

Hardness in water titrations go fully automatic

Fully automatic determination of the total, calcium and magnesium hardness of water samples using photometric titration. The total hardness is the sum of calcium, magnesium, barium and strontium ions. Since in drinking water only calcium and magnesium are present in significant amounts, the hardness is entirely determined by their content....

Determination of Oxyhalides in Swimming Pool Water

The separation and determination of oxyhalides besides standard anions is performed on a Metrosep A Supp 5 – 250/4.0 column with subsequent sequential suppression followed by conductivity detection. Metrohm’s experts have develop an IC application for the determination of oxyhalides besides standard anions in swimming pool water. Swimming pool water...

Ultratrace-level perchlorate in water according to USEPA method 314.0

The figure showing the results of the determination method: Perchlorate in 3000 ppm TDS L : 0.5 μg/L Lowest concentration minimum reporting level (EPA-LCMRL required: 0.57 μg/L) : 0.11 μg/L Perchlorate (ClO4–), is a manufactured chemical used as the main ingredient of rocket fuel, safety flares, matches and fireworks. It...

Bromate in Water According to EPA 300.1, 317, and 326

Bromate in water according to EPA 326: Post-column derivatization with KI and UV detection. Bromate in water, especially drinking water, is harmful and undesirable. Exposure to large amounts of bromate for a long period of time may damage kidney or even cause cancer. This led to the Safe Drinking Water...

pH basics explained. Download the Application Bulletin 188 to learn more. Metrohm is pleased to present an Application Bulletin presenting the basics of pH measurement. pH Basics Explained Application Bulletin 188 “pH measurement technique” explains the basics of pH measurement. It starts with prerequisites such as electrode calibration, reagents needed, and potential...

Is CO2 a problem for your alkalinity measurement?

The Metrohm Dis-Cover sample processor system keeps CO2 out of your sample prior to alkalinity titration. The Metrohm 815 Sample Processor is a high quality, fast and high throughput sampler, which when combined with a suitable titration module such as the 905 Titrando, can easily perform your most difficult alkalinity...

Toxins in our environment – straightforward determination of hexavalent chromium by ion chromatography

Are our rivers as healthy as they look? Generally speaking, hexavalent chromium or Cr(VI) is classified as allergenic, carcinogenic and extremely toxic, and is subject to strict monitoring. Cr(VI) can occur in various concentrations in different areas, e.g. drinking water, toys and textiles. Metrohm has developed ion chromatography determination methods...

Chromium Speciation in soil, solids and pharmaceuticals via IC-ICP-MS

Chromatogram for a microwave extract generated from a soil sample double-spiked with 50Cr(III) and 53Cr(VI). Chromium is encountered primarily in two forms: Cr(III) and Cr(VI). Whereas Cr(III) compounds pose no major risk (and are essential for humans), hexavalent chromium (also called hexachrome, chrome-6, and Cr(VI)) is harmful. The strong oxidizing...

Monitoring Boron levels in desalination plant

Metrohm has recently installed three Metrohm-Applikon ADI 2019 Process Colorimeters to perform on-line boron analysis in a local Australian desalination plant. The ADI 2019 Process Colorimeter performs photometric absorption measurements in the visible light range and also contains a thermostated cuvette with 3 cm light path and LED technology. The...

Fast Ion Chromatography
