CRMS-NP

Skeletal fragments of Corallium rubrum were used to make this material. These corals grow on a rocky seabed at a depth of 10 to 300 m, primarily in the Mediterranean Sea.Attention: We are currently certifying the next CRMS-NP reference material batch for you. Especially performing homogeneity and stability tests.While the absolute certified values for CRMS-NP-B01 are valid for all batches of the material CRMS-NP, the uncertainties according to the ISO guidelines are not exactly transferable to all methods or batches.Therefore, the CRMS-NP Nano-Pellets for LA-ICP-MS (10 mm) are currently also available as recharacterised material (RCM) with its own product information sheet.

Background

Processed Material - PCM
Most of the materials we currently have in our portfolio are processed materials - PCM. Materials from this category are purchased reference material powders, which we process using our innovative technology. During the process, the powder is subjected to our own material-specific milling protocol and pressed into pellets without any binders using a programmable hydraulic press. All information about the data and the original manufacturer can be found in the respective product information sheet.

Recharacterized Material - RCM
Recharacterized materials - RCM - either undergo the same process as processed materials, with the difference that we add an analytical step in which the nano-powders are analyzed in competent laboratories using various methods, or they correspond to certified reference materials where the uncertainties are not exactly transferable to the current batch or selected method. Information on the results and the procedure can also be found in the product information sheets.

Certified Reference Material - CRM
The third category identifies the certified reference materials – CRM. This tag is only given to products that are produced by us in accordance with the standard ISO 17034, meaning the nano-pellets are tested for homogeneity and stability, and the nano-powder is characterized in competent laboratories. In contrast to the basic properties of a simple reference material, the requirements for a certified reference material are more stringent, this is made clear by the definition of ISO.

No classification - Pressed Pellet
For pressed pellets, the original material is used. This means that no further processing of the powder takes place.
