Ion Chromatography
Ion chromatography requires the constant use of calibration solutions. EMD offers a wide range of single- and multi-element solutions for this purpose. Recent additions include the multi-element solutions for environmental analysis. For this purpose, a new standard has been developed based on nitrogen and phosphorus rather than the previously used ions nitrate and phosphate. All ion chromatography standards – with the exception of fluoride – are traceable to NIST (National Institute of Standards and Technology, Gaithersburg, USA) standard reference materials.
