What purities are available for gold?
In the field of gold laboratory supplies, ChemPUR offers gold in various purity levels, optimally matched to the requirements of modern research, development, and analytics. Choosing the right purity is a relevant factor for reproducible results and reliable processes in the laboratory and in industrial applications.
Typically, the following purity grades are available:
- 99.9% gold for general applications in research and technology
- 99.99% gold for demanding analytical and material science processes
- 99.999% gold for highly sensitive applications with the highest purity requirements
These gradations allow for the selection of the appropriate material depending on the application area – from robust standard applications to high-precision special processes. Especially in areas such as thin-film technology, catalysis, or analytical chemistry, purity plays a central role, as even minor impurities can affect results. Gold, as a noble metal with the element symbol Au and CAS number 7440-57-5, is characterized by exceptional chemical stability and resistance. These properties make it a valuable material for numerous scientific and technical applications.
At ChemPUR, you receive all substances with clearly defined specifications and – depending on the product – with an analysis certificate. This allows you to trace the quality and ensure that your requirements are met. If you are unsure which purity is optimal for your application, we will gladly provide expert guidance. Together, we will determine the appropriate specification for your processes.
Do you also offer gold as a nanomaterial?
Yes, ChemPUR also offers gold as a nanomaterial. Our product range includes Gold Nanopowder APS 50–100 nm / 99.99%, thereby covering the demand for high-fineness gold materials for research and development. If you are looking for gold nanoparticles in a professional context, the specific product selection depends on the type of material needed and the specifications required for the respective application.
Areas of Application and Target Groups
This product is particularly aimed at institutions in research, materials science, and technical research needs that work with very fine particle sizes. Are you planning test series with defined parameters or investigating material behavior in the micro or nano range? Then it is important that the selected products match your research question. Even in early development phases or new projects, it is crucial to be able to react flexibly to different requirements. Especially here, it is important that materials are available in suitable quantities and with clearly defined properties.
Important Selection Criteria in the Nano Range
In the nano range, several factors interact: in addition to particle size, their distribution, purity, and reproducibility are also relevant. Even small deviations can affect experimental results. Therefore, it is important to tailor the selection specifically to the respective application from the outset. Furthermore, aspects such as handling, storage, and further processing should also be considered. These points are often underestimated but have a direct impact on practical implementation in daily work.
Support with Selection and Procurement
We support you in determining the appropriate version for your specific needs. Together, we clarify which specification makes sense and in what purchase quantities procurement remains practical. This allows both initial small-scale experiments and recurring needs to be sensibly covered. The Gold Nanopowder is available in several quantities, for example as 1 g, 2 g, 5 g, or 10 g, and can thus be ordered in practical packaging units. This allows you to flexibly adapt the required quantities to your needs.

What role does gold play in the medical field?
In the medical field, gold primarily plays an important role in research, development, and analytical processes. Especially in laboratory medicine, the noble metal is valued for its stable properties and excellent resistance to external influences. A decisive advantage is its high resistance to corrosion, particularly in contact with aggressive media such as acids. This makes gold suitable for examinations and analytical procedures.
In practice, gold is often used as a reference material or a component of special devices employed in analytical methods. These are used, for example, in the detection of certain substances or in the investigation of chemical reactions. Even in thermo-related processes or at elevated temperatures, gold remains stable and shows no undesirable interactions with other substances.
Another aspect is its processing in different forms. Due to its good malleability, gold can be used in a versatile manner, for example in coatings, contacts, or special components. In certain cases, gold is also used as a synonym for particularly high purity and reliability, primarily when it comes to demanding analytical processes.
In the context of research, the term colloidal gold is also frequently used. This refers to a special form used in certain diagnostic procedures. In contrast, our product range focuses on defined gold forms and specifications that are specifically used for analytical and technical purposes.
Furthermore, gold also plays a role in handling and storage. In combination with glass or as a component of laboratory bottles, it can help ensure stable and reproducible conditions. In summary, gold in the medical field is not a classic consumable but a specifically used element for precise investigations, analytical procedures, and qualitative results.
Who is allowed to purchase gold for research purposes?
Gold can generally be procured by various institutions and organizations, provided there is a legitimate need in a scientific or technical context. This includes universities, research institutions, institutes, and development departments in companies.
Industrial companies that develop new materials, processes, or technologies are also typical customers. In these cases, gold is often used for experiments, analyses, or technical tests. Furthermore, laboratories, technical service providers, or specialized dealers can also acquire gold for corresponding purposes.
It is important that the use is clearly traceable and takes place within the framework of research, development, or analytical activities. The purchase is therefore not limited to a specific group of people but is based on the intended use. In the procurement process, technical buyers, laboratory managers, or project managers often play a central role. They define the requirements, select suitable products, and organize the order.
Depending on the product and application, additional requirements may apply, for example, regarding documentation or specification. Here it is important to choose a supplier who provides the necessary information and enables a clear assignment of products. Anyone who needs gold for scientific or technical purposes and can demonstrate its use accordingly may procure it within the framework of applicable regulations.
