• Application: Phosphorus Standard in Liquid-Liquid Extraction: Phosphorus standard solutions are crucial for optimizing the Hofmeister bias in salt liquid-liquid extraction processes, enhancing the performance of arylethynyl bisurea anion receptors in inductively coupled plasma (ICP) analyses. This application facilitates more precise separations and extractions in chemical science research (Fargher et al., 2024).Pharmaceutical Elemental Analysis: The use of phosphorus ICP standards is integral in a novel method for simultaneously measuring boronophenylalanine uptake in brain tumor cells. This application underscores the importance of phosphorus standards in enhancing the accuracy of elemental analysis using inductively coupled plasma atomic emission spectroscopy in medical research (Li et al., 2024).Trace Element Calibration in Cementitious Materials: Phosphorus standards are utilized in the analysis of cementitious materials to ensure accurate measurement of trace elements, which is vital for assessing materials′ properties such as frost resistance. This usage highlights the role of phosphorus ICP standards in maintaining rigorous quality control in construction material research (Zhang et al., 2022).Biotechnology Research for Drug Delivery Systems: In the field of biotechnology, phosphorus standards are employed for the simultaneous quantification of oligo-nucleic acids and ferritin nanocages by size-exclusion chromatography hyphenated to ICP mass spectrometry. This method is pivotal in developing drug delivery systems, demonstrating the critical role of phosphorus standards in pharmaceutical research (Yamazaki et al., 2022).Biological Studies on Elemental Uptake: High-purity phosphorus standards are used to explore phosphorus and heavy metal uptake by single cells of Saccharomyces cerevisiae. This research enhances understanding of intrinsic elements in microbial cells, showcasing the utility of phosphorus ICP standards in microbiological and biochemical studies (Qin et al., 2022).
