“The training provided during installation was excellent” Dr. Fiona Spellissy BSc, MSc, PhD., Station Chemist/Environmental Coordinator at Carrington Power Station, Manchester.

Carrington Power Station is a Combined Cycle Gas Turbine power station, which was completed in Autumn 2016 and began commercial operation on 18 September 2016.

The IC is used on site at Carrington Power Station to test process water to determine the quality of water fed to the steam turbine. Both CCGT units were commissioned in the summer of 2016 and the IC proved invaluable during this period. It aided in determining issues with chloride slippage from the process water treatment plant, issues with polisher regeneration leading to sulphate slippage and with determining the causes of high CACE in steam samples. It was also used to modify our start up regime, leading to a decreased start up time of ~ 40 minutes leading to significant financial saving.

I have a single stream IC which I continually change between anion and cation analysis. I find it very quick to switch between cations and anions, it generally takes ~10 minutes and I find that columns/suppressors used don’t dry out as I experienced with other IC manufactures. 
I found that the training provided during installation was excellent and the operation manuals supplied with the instrument are very thorough. Metrohm’s aftercare is excellent, the IC requires that eluent be made up for use, initially when the instrument was purchased our purchasing system was not in place and I have issues with buying reagents. On several occasions Metrohm’s lab made up reagents for me while I was waiting to order reagents. This allowed me to use the IC at a critical time in the commissioning process.
