What is Ion Chromatography?
Ion chromatography is a method of separating ions according to their interactions with a resin (the stationary phase) and an eluent (the mobile phase). These phases differ between an anion-attracting column and a cation-attracting column.
What is Ion Chromatography Used For?
Ion chromatography is becoming a critical tool for pharmaceutical analytical chemists. The technique is well-suited to the analysis of ions in pharmaceutical applications due to its high sensitivity in addition to its wide dynamic operating range.
What are IC Standards?
The Inorganic Ventures team has a wealth of experience in advanced fractionation and wet chemistry. This has helped us produce a line of certified reference materials (CRMs) which are specifically suited to IC and IEC operations. Our portfolio includes a range on anion standards, cations and multi-ion blends which are well-suited to routine calibration of ion chromatographs (ICs).
With the view of delivering a higher class of CRMs at a fair price point, we have successfully stabilized more than 12 exclusive reagent-grade anion and cation standards. This success is used to supply a range of high-purity single-element IC standards and leveraging these materials in custom-blended CRMs.
Anion Standards
Anion standards are a type of IC standard and refined control material which are employed in quality assurance and control applications in ion chromatography. We offer a range of made-to-order anion IC standard solutions which are fully NIST-traceable and are engineered for stability and ease-of-use.
Cation Standards
This type of IC standard is made up of cations. Cations are positively charged ions, formed when a metal loses its electrons. As such, cations possess a net positive charge. Some cation examples are calcium(Ca2+), potassium (K+) and hydrogen (H+).
Multi Ion Standards
This type of IC standard involves the electrochemistry of multiple ions in various electrode materials and electrolytes. They are dedicated to combining individual qualities of multiple ions as primary ions in rechargeable batteries.
Eluent Concentrates
Eluents are used to push the sample through the chromatography column. The eluent is pumped through the column so the sample can interact with the column phase whilst it travels through the column.
Common eluents for use in ion chromatography include Sodium carbonate, Sodium bicarbonate, Potassium hydroxide, and Methanesulfonic acid. Any contamination present in the eluent will raise the background signal. The purity of your eluent is key to obtaining low detection limits.
EPA Standards
In 1972, The Clean Water Act and the Safe Drinking Water act of 1974 created guidelines and methods for creating and controlling water quality standards in both surface and drinking water. All EPA IC standards by Inorganic Ventures are NIST-traceable, employ high-purity starting materials, and are formed in to adhere to the strict Quality Assurance guidelines.
