Merck KGaA, Darmstadt, Germany products

With Certipur® AAS standards from Merck, you benefit from both a comprehensive portfolio and top quality for highest precision. All our AAS standards are traceable to standard reference materials from NIST. Merck offers AAS standards for a wide range of elements and ensures their accuracy and purity through strict quality control procedures. Quality management for Certipur® AAS standards is carried out using ICP-OES by our own calibration laboratory in Darmstadt, Germany, that has been accredited according to DIN EN ISO/ IEC 17025. Merck AAS standards come with an extensive, batch-specific Certificate of Analysis documenting data on the certified value, measurement uncertainty, composition, traceability, date of release and minimum shelf life.

As your one-stop provider for instrumental analysis via Atomic Absorption Spectroscopy (AAS), we offer a comprehensive choice of reagents for use in sample preparation as well as in calibration. Our portfolio of auxiliary reagents for optimizing analysis conditions comprises selected matrix modifiers and spectroscopic buffers for AAS measurements. Sample preparation is always a critical step in atomic spectroscopy analyses. In AAS applications, the reagents used for sample preparation must be very pure in order to make sure to reliably determine the trace elements you are analyzing for. To ensure that the measurement isn’t affected by interference it is recommended to use matrix modifier and spectroscopic buffer. Both reagents are available in a small range of elements or in different composition to suppress the interference.
