Ion chromatography (IC) is a technique in which ions are separated based on their interactions with a resin and an eluent (known as the stationary and mobile phase respectively). These phases change between a cation-attracting column and an anion-attracting column.

Samples are pumped into a chromatographic column that contains an ion exchange medium to separate the ionic speeds in the sample with respect to their inherent physiochemical properties. IC instruments can utilize a variety of detectors to ascertain the retention times of separated analytes. The most common detector type for IC applications is the conductivity detector. To ensure high sensitivity, the IC instrument must also compensate for background detector signal coming from the mobile phase. A properly configured IC instrument can produce excellent quality results in the ppb to ppm concentration range.

Ion chromatography using IC standards is a key tool for pharmaceutical applications as it is extremely

Many chemists often resort to custom mixing their own analytical standards in house. However, there are pitfalls to this method, including extra hassle and no small amount of risk.

Fortunately, there is a better solution. Custom certified reference materials (CRMs) from Inorganic Ventures represent an easier, faster way to secure the right analytical standard reference material for your specific use case.

We always encourage our clients to share the burden of securing calibration standards. Allow us to shoulder the weight of manufacturing custom analytical standards based on your unique needs. This mitigates the time inefficiencies associated with off-the-shelf products, as well as the risk of blending analytical standards yourself in the lab.

Not convinced that custom CRMs are superior to analytical standards mixed in-house? Here are six reasons you should trust us to develop calibration solutions for your workflow, rather than blending them yourself.

There is often confusion regarding the differences between our single-element AAS standards and single-element CG standards. This article serves as a detailed description of the main differences between the two product lines.

Uses of AAS Standards and CG Standards

AAS standards and CG standards are often used in the medicine and pharmaceutical industry and have been revolutionary in the detection of trace toxins in medicines. AAS standards and CGs have also led to the detection of elements which were previously not known to exist in certain materials, such as the presents of molybdenum and cobalt in soil. AAS and CG standards are frequently used in the detection of precious metal levels in rocks in mining operations.

Difference in Scope Between Custom Grade and AAS Standards

CG standards are manufactured and certified under our ISO 17025 and ISO 17034 Scopes, while AAS standards are manufactured and certified under ISO 9001 only.
