一般描述
EMPLURA® is our low-cost alternative to high-purity qualities. With EMPLURA we offer a range of solvents for a plurality of basic applications in non-regulated industries and for less demanding applications, preparative laboratory work and cleaning purposes. EMPLURA solvents provide adequate specifications with the most important parameters.
应用
- Metal Extraction and Digestion: Nitric acid (60%) is extensively used for the extraction and digestion of metals from various samples. This application is crucial for preparing samples for subsequent analysis by techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Atomic Absorption Spectroscopy (AAS). Recent studies have compared the efficiency of nitric acid treatment with microwave digestion for extracting metals from bioprocess samples, demonstrating its effectiveness in achieving high recovery rates and accuracy (Mohammad and Madhavarao, Analytical Biochemistry, 2024).
- Food and Beverage Analysis: Nitric acid is employed in the analysis of food and beverage samples to determine the mineral composition. For instance, the acid is used in microwave-assisted decomposition of foods like rice, carrots, and chayote, facilitating the determination of elements such as aluminum, cadmium, chromium, copper, iron, and lead. This application is vital for ensuring food safety and compliance with health standards (Serafim et al., Brazilian Journal of Analytical Chemistry, 2024).
