Ion chromatography has a wide range of uses in all sorts of scientific processes and experiments, and now two US agricultural scientists say it could be ideal for analysing cereal grains.
Cecil Instruments is a world-leader for ion chromatography systems, as many scientists around the globe will know.
The company says its IonQuest ion chromatography systems ensure scientists can carry out their analyses smoothly and effortlessly, and with the versatility they require for different applications. Continue reading
In order to respond to public concerns over the quality of water in Dubai, the emirate has been utilisng ion chromatography in lab testing.
Maha Shoukat Al Hajri, head of food and environment at the Laboratory of Dubai Municipality, said it is always sure to confirm and maintain the quality and safety of Dubai’s drinking water, AMEinfo reports. Continue reading
With the search on to find an alternative to oil and petrol ion chromatography can be a useful tool in the development of biofuels.
According to scientists at the University of Campinas in Brazil ion chromatography could be a cheap and convenient way to determine the levels of the four cations that commonly contaminate biodiesel. Continue reading

Ion-exchange chromatography has been around since the mid 19th century. English researchers H Thompson and J T Way first used ion methods to treat clays with ammonium sulfate or carbonate in solution in order to extract the ammonia and release calcium.
Nearly 80 years later, the first zeolite mineral column was used to remove calcium and magnesium ions from a solution so that the sulfate content of water could be accurately determined. Continue reading
Scientists have been able to make certified reference materials (CRMs) more accurate, even for ion chromatography processes.
Analysts rely on CRMs to identify unknown analytes in a sample and also to calibrate analytical instruments and make allowances for environmental factors.
This means the CRMs must be exact in every aspect, including purity and mass fraction, so that scientists can rely on the measurements. The figures must be the same across different samples of the same CRM, so manufacturers must take great care when producing standardised CRMs and ensure they are in-line with the master version of the material.

Scientists at the UK’s Cambridge University have developed a quick and easy way to separate proteins.
By rolling up a novel microcapillary film, chemical engineers have advanced the ion chromatography process.
They used an 8 mm-wide polymer strip, impregnated with 19 tiny capillaries along the length. The strip was fabricated by a novel extrusion process involving flowing hot, liquid polymer over the capillaries, which allows any length to be produced. Continue reading
