Wet chemistry is an extremely broad field unified by the fact that chemical analyses and experiments are carried out using liquid phase samples. Prior to the advent of theoretical and computational chemistry, wet chemistry was the standard and as such it is often referred to as classical chemistry.
Due to wet chemistry being used abundantly in the modern world, many methods have been automated and computerized for streamlined analysis. The need for streamlined analysis has also meant that analytical standards have become increasingly important.
Forms of Wet Chemistry
Qualitative chemical testing is a form of wet chemistry where analytical standards are used as reagents to indicate the presence of a particular chemical. The analytical standards are extremely pure and stable, meaning it is possible to be sure of the composition of the reagent and determine which chemical is present by how the sample reacts with the analytical standard.
Quantitative volumetric analysis/titration is another form of chemical testing in which volume measurements are used to ascertain the quantity of a chemical in a sample. An analytical standard is used as a reagent with a known volume and concentration and combined with a solution which has an unknown substance and concentration. The analytical standard added can help determine the quantity of the unknown substance.
Important Attributes of Analytical Standards
As analytical standards are a key component of accurate chemical analysis, they must have extremely high levels of purity. The analytical standards must also have low-reactivity so that they will not have any unplanned reactions with substances in solutions. Analytical substances must also be unlikely to absorb moisture from the air as masses need to stay uniform. It is also important for analytical standards to be cost-effective as testing is normally performed multiple times per sample.
Inorganic Ventures Analytical Standards for Wet Chemistry
Analytical standards from Inorganic Ventures have been produced to be used in wet chemistry applications. These analytical standards are NIST-traceable, compatible and stable and have been manufactured to adhere to ISO 17034 and ISO 17025 guidelines. The wet chemistry analytical standards use high-purity starting materials for reliable quality assurance.
