IROST Researcher Offers New Method for Simultaneous Measurement of Mineral Elements
Dr. Maleeheh Safavi, head of the Biotechnology Research Institute at the IROST said that she and her teammates in the institute have built a system for the simultaneous measurement of mineral anions and cations, carboxylic and short-chain sulfonic acids with an easy and cost-effective method, according to a report by the IROST website.
The previous methods including spectrophotometry, laboratory kits, atomic absorption, ICP and ion chromatography to measure mineral anions and cations such as "potassium" (k), "sodium" (Na), "magnesium" (Mg+2), "calcium" (Ca+2), "ammonium sulfate" (NH4+), " "bromic acid" (BrO3-), "chlorine" (Cl), "bromine" (Br), "nitrogen dioxide" (NO2), etc. in different samples have proven to be expensive and some are insensitive.
“Given the high costs ans the restrictions that single-element measuring method of each of the above-mentioned methods face, a new method that is fast, accurate and multi-element while it is cost-effective became a necessity. In this regard, the IROST Liquid Chromatography Laboratory after months of efforts have been able to design a new method to simultaneously measure inorganic anions and cations (a positively charged ion), as well as short-chain carboxylic and sulfonic acids,” Safavi said.
According to her, the designed device measures the favored elements using the high performance liquid chromatography (HPLC) technique with general detectors such as UV, RI, as well as the inexpensive mobile phases.
The IROST researcher further voiced her institute’s readiness to perform the simultaneous measurement of the above-mentioned elements and to provide services to all educational, research centers, hospitals and also relevant laboratories across the country.
The report further said that the research institute is optimizing a simple and cheap method for the analysis of amino acids in biological, food and pharmaceutical samples.
