Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule or suspended solids.

Mercury is a naturally occurring element found in the air, water and soil however exposure to the substance, even in small amounts, can lead to severe health and ecosystem issues. Mercury in products can find it’s way into the environment in all sorts of ways such as manufacturing, spills, recycling and disposal. Due to the health risks posed products such as mercury-containing thermometers are being phased out in the US under guidelines produced by the Environmental Protection Agency (EPA) and in the EU the European Commission REACH aims to heavily reduce the use of mercury in products.
There are a range of mercury autoclave thermometer alternatives available that produce as accurate readings whilst keeping in line with the new US and EU standards and reducing the health risks.

Ask The Expert: What is the challenge with the dichromate COD approach and why is an alternative method required?
Answer: The traditional COD analysis approach has been used for decades and is based on the use of potassium dichromate, one of the reagents necessary for dichromate COD (CODCr) analysis. Dichromate is listed as a “Substance of Very High Concern” on the Annex XIV list of the European Union’s REACH regulation.
