 
| Certipur® Certified Multi-Cation & Multi-Anion Standards for Ion Chromatography | 
Within its Certipur® range of certified reference materials,Merck provides various Certipur® multi-element standards especially designed for instrument calibration in ion-exchange chromatography (IC) applications, e.g. for environmental or food analysis and quality control. 
Our Certipur® multi-element standards for ion chromatography are available as both anionic and cationic solutions. For environmental analysis, we also offer a multi-element standard based on nitrogen and phosphorus instead of nitrate and phosphate ions. All our Certipur® IC standards – with the exception of fluoride – are traceable to primary standard reference materials from NIST.
