Atomic absorption spectroscopy (AAS) is a high throughput, easy-to-use, and inexpensive technology primarily used to analyze compounds in solution by applying wavelengths of electromagnetic radiation. AAS is commonly used in flame atomic absorption spectrometry (FAAS) and graphite furnace atomic absorption spectrometry (GFAAS). Relying on the property of individual atoms to differentially absorb radiation wavelengths, this technology has a plethora of applications including in the analysis of water, food and beverages, and pharmaceuticals, as well as in mining operations to determine the percentage of precious metal in rocks.
The Importance of Releasing Agents
In the process of AAS analysis, analytes are first atomized, in which they are stripped from the solvent, volatilized and, if necessary, dissociated into free atoms. This process allows the characteristic wavelengths of each atom to be emitted and recorded later in the process. The atoms are then excited
Inductively coupled plasma (ICP) spectroscopy is an analytical technique designed to detect and measure elements from chemical samples. As such, it has a range of applications and is especially important in the biomedical and pharmaceutical industry.
ICP spectroscopy is based on the ionization of a sample by plasma, typically generated through the ionization of argon gas by radio frequency energy. Commonly employed in inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP-OES), these two instruments have a number of advantages over comparable technology used for trace element detection. Notably, they allow multiple elements to be measured simultaneously and possess a large analytical range, which outstrips the single element capabilities and limited analytic range of flame atomic absorption and flame atomic emission.
The vital role played by ICP spectroscopy in many industries

At Inorganic Ventures, we stand by our high purity standards. Registered as an ISO 9001 company and recognized as holders of ISO 17025 and ISO 17034 accreditations, our customers can trust the high purity standards of our products and the services that we proudly promote.
Possessing the necessary knowledge and resources to manufacture almost any inorganic certified reference material (CRM), we have built a reputation for highly purified solutions. Catering for applications in ICP, ICP-MS, IC, atomic absorption, wet chemistry, and QC, custom standards and our team’s reliability in replicating them has become our specialty.
An Overall Achievement of High Purity
Through a combination of lab-based developments and continued consultation with a new type of ambitious and creative customer w
Coal- and oil-fired power plants are responsible for an inordinate amount of the toxic pollutants present in our atmosphere. According to the US Environmental Protection Agency (EPA), they can generate mercury emissions exceeding 53 tonnes per year, representing 50% of all mercury air pollution in the country. Mercury and air toxins are extremely damaging to human health and to our environment, hence the importance of the Mercury and Air Toxic Standards (MATS) rule implemented by the EPA. But stricter regulations on pollution control must be accompanied by improvements to standardised environmental screening and analysis.
NIST-traceable mercury standards fit the bill when it comes to inorganic trace analysis of pollutants via inductively coupled plasma atomic emission spectroscopy (ICP-AES).
Using Mercury Standards in Trace Elemental Analysis
ICP-AES is a powerful tool for trace-level elemental analysis that has only been implemented
NIST-traceable standards are reference materials certified to specific values laid out by the National Institute of Standards and Technology (NIST). They are designed specifically for standardized instrument calibration and quality assurance protocols aimed at eliminating measurement uncertainties. The implication with NIST-traceable standards is that all calibrations are part of an unbroken chain of comparisons from the manufacturer through to the end-user, which is where the term traceability comes from.
Traceability is a crucial parameter in elemental analysis and wet chemistry applications. When we talk about the traceability of measurements, we are referring to systemic reliability – and subsequently the reliability of your results – relative to an accepted set of standards. This is the basic premise of standardized metrology and the international system of units (SI). Yet the traceability of chemical measurements is
Inorganic Ventures is one of the world’s foremost manufacturers of high-class certified reference materials (CRMs) for analytical and preparative chemistry. Though off-the-shelf standards are often suitable for system calibration in certain applications, we specialize in the development of custom standards designed to meet specific end-user objectives. Whether you need single-element reference materials for inductively-coupled plasma (ICP) spectroscopy or multi-anion standards for ion chromatography, we can supply fully-traceable solutions that meet your exact specifications.
Anion standards are finely-tuned control materials used for quality assurance and control (QA/QC) purposes in ion chromatography. At Inorganic Ventures, we offer a suite of made-to-order anion standard solutions in single- and multi-anion formats at specific, user-defined concentrations.
Using Anion Standards for IC
Ion chromatography, or ion-exchange chromatography, is an industry-trusted a
