Water Analysis with Shimadzu

Pure water is the source of life. Its quality can be affected by land contamination when toxic elements find their way into ground- and drinking water. From there, contamination influences crop farming and as result our food and grocery products. As a company for consumer and product safety, Shimadzu offers the entire bandwidth of technologies to cover application challenges in water science through various analytical instrumentation technologies. Read below some important articles with our solutions included. 

1. Wastewater Analysis

Emerging chemical contaminants: Water analysis moves up a gear.

Rapid ppt-level monitoring of little-understood water-borne chemicals using LCMS.

The issue of environmental pollutants has recently been in the spotlight and is set to receive more attention as the hazards that some chemicals pose to human and environmental health become clearer. We talk to Dr. Leon Barron and Dr. Helena Rapp Wright at Imperial College London about how they’re using Shimadzu’s LCMS-8060 and LCMS-9030 to conduct large-scale, rapid analyses of wastewater and river water, and how the insights they gain are contributing to a better understanding of the thousands of unregulated chemicals about which little is known – so-called “emerging chemical contaminants”.

Determination of organic pollution of wastewater

A comparison between COD and TOC

The European Union continues to limit the use of toxic chemicals. Chromium VI (CrVI) for instance is a highly toxic substance and is used in electroplating or in wood preservatives. In Annex XIV of the European Chemicals Regulation REACH, it is listed as a ‘Substance of Very High Concern.’ Chromium VI is, however, also one of the most important reagents for COD analysis (chemical oxygen demand), which is used as a sum parameter to quantify the pollution of wastewaters with organic compounds.

2. 360° Drinking Water Analysis Trilogy

Episode 1. Qualified water - Contaminants and continuous monitoring

Although two thirds of the Earth’s surface are covered by water, only 2,5 % is fresh water with low concentrations of salt. An even smaller portion is suitable for drinking, and only then when purified before consumption. Specific chemical and physical properties make the difference between potable and undrinkable water. Groundwater and surface water from lakes and rivers, so called raw water, is the most readily available resource for drinking water production. But there’s a long way to go before the water reaches the glass.

Episode 2. Automatic, simultaneous and rapid analysis of pesticides in drinking water by online SPE and UHPLC-MS/MS"

EU citizens use up to 156 liters of water per day. Groundwater and surface water such as rivers, lakes, reservoirs and seawater are sources for drinking water. Its safety and high quality are essential for public and individual health as well as for the economy.

Episode 3."Best things come in small packages.

Determination of anions in drinking water using ion chromatography

The determination of inorganic ions in drinking water samples is an important application for drinking water suppliers. For the quality control of drinking water, ion chromatography (IC) with suppressed conductivity is suited perfectly due to its high sensitivity and selectivity. IC is an established method for analysis of anions listed in main standards for analysis of drinking water in accordance with the regulations in US and Europe.

3. Seawater Analysis

Climate research in the ocean - An alternative method for the determination of carbon dioxide in seawater

The world’s oceans have been carbon dioxide sinks since eons. CO2 from the air is permanently bound in the sea by creatures that use calcium carbonate to build their skeleton. An American scientist team conducted a long-term experiment with corals at the Leibniz Center for Marine Tropical Research (ZMT) in Bremen, Germany. The TOC analyzer based DIC (Dissolved Inorganic Carbon) method demonstrated its suitability as a safe, exact and fast alternative method for the investigation of seawater.
