Customers rely on robust Metrohm Ion Chromatography systems

Robust, fully automated inline sample preparation, stable, reproducible results, a dependable suppressor that works flawlessly for years – the reasons why customers prefer Metrohm ion chromatographs for routine analysis are many.

>>For robustness and precision

“We like the Metrohm IC system as it has a single auto sampler which allows us to run both methods simultaneously. Another key feature we find is reagent used for the Oxyhalides is continuous auto regeneration, so we don’t have to worry about constantly filling up reagent”, says John Robertson, Senior Chemist at South East Water who run a range of different methods on their Metrohm IC.

>> Extreme reproducibility

“We chose Metrohm IC as alternative IC systems cannot cope with neat agrochemicals. The benefit of using Metrohm IC is saving downtime and not requiring hugely expensive parts and repairs. Plus Metrohm after sales service and support is fantastic!” says David Norris, Managing Director, David Norris Analytical Laboratories.

DNAL use their Metrohm IC to accurately measure the concentration of anions and cations in pure salts and look for salts as impurities in Agrochemicals and Biocides. Many of these provide a challenging matrix as they are pure organic compounds and are highly soluble such as quaternary ammonium compounds. Challenges faced are low throughput but high precision and exact determinations to provide a complete profile of the salts present in the products. They need robustness and extreme reproducibility.

>> Invaluable automation

Bardyke Chemicals is a chemical manufacturing company based in Blantyre near Glasgow. The company specialises in developing and manufacturing copper compounds. In 2008 the company purchased a Metrohm 881 compact IC pro for the analysis of anion impurities in both final products and raw materials. To increase the throughput of the instrument an 858 Professional Sample Processor was purchased in 2009.

Michelle Higgins, Laboratory Manager speaks about her experience, “The level of automation has proved invaluable, I particularly like the timer function which can be set to equilibrate the instrument or run an analysis method when the laboratory is unmanned. I have found the instrument to be extremely robust and reliable and have had no issues with maintaining the instrument. Metrohm has recently carried out an onsite training programme with the laboratory staff, which all members of staff found extremely helpful. The online tutorials with step by step instructions for changing consumables on the instrument are excellent. I am very happy with the level of service from Metrohm and have found their staff to be very knowledgeable and always willing to help.”
