Általános leírás

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Alkalmazás

• Cadmium Standard for Atomic Absorption Spectroscopy: An article in Heliyon (2024) explores the pollution indices and correlation of heavy metal contamination, including cadmium, in groundwater near industrial sites. This emphasizes the role of cadmium AAS standards in monitoring environmental pollution and ensuring compliance with safety regulations (Mohan et al., 2024).


• Trace Metal Analysis in Food Samples: In a Food Chemistry study (2024), cadmium standards are crucial for the development of novel electrochemical strategies for detecting cadmium in grain and water, using advanced materials like MXene@rGO composite aerogels (Dong et al., 2023).


• Quality Control in Pharmaceutical Research: The need for precise cadmium calibration standards is underlined in another Food Chemistry publication (2024), which discusses simultaneous electrochemical sensing of heavy metals in food, demonstrating their vital role in ensuring the accuracy and reliability of pharmaceutical and biotechnological analyses (Mirzaei Karazan et al., 2024).
