Ion chromatography is one of the best methods for the quantitative analysis of ions in the parts per trillion (ppt) range. Thanks to the development of modern columns and apparatus, Ion chromatography is a fast, reliable, and simple tool for analysis. Using custom IC standards means that you’re not limited to a set range of blends, but free to create more unique standards that perfectly suit your needs. Read on to discover the benefits of ion chromatography and how custom IC standards can elevate your analysis.
What is ion chromatography
Used for water chemistry analysis, Ion chromatography can measure concentrations of major anions, such as fluoride, nitrate, nitrite, chloride, and sulfate. The method can also measure major cations, such as lithium, sodium, ammonium, calcium, potassium, and magnesium.
Ion chromatography works by measuring concentrations of ionic species and separating them based on their interaction with a resin. The way the species separate depends on varying types and sizes. During the process, sample solutions pass through a pressurized chromatographic column where ions are absorbed by column constituents. Meanwhile, eluent, which is an ion extraction liquid, runs through the column causing the absorbed ions to start separating from the column.
Applications for ion chromatography
Ion chromatography is often used for applications such as:
- Drinking water analysis for identifying pollution and other constituents
- The determination of water chemistries within aquatic ecosystems
- Isolating select proteins
- Determining sugar and salt content in food
IC standards for ion chromatography
The quality control and calibration within ion chromatography are of utmost importance, and so it requires the careful selection of appropriate standards. Delta offers a wide range of reference materials, as the standards are frequently used across a wide range of industries, including food and beverage, pharmaceutical, and many more. This means that you can have your custom IC standards made to your exact specifications and access a range of benefits. For example, single element stock products require high levels of preparation and the costs that are associated with this, but a custom IC blend is ready for immediate use so can save you money on labor and equipment. Plus, you can rest assured that your custom IC standards come complete with the correct documentation and associated paperwork, as well as being traceable to NIST certifications.
