Selective and Sensitive determination of Zinc in Various OTC formulations as per USP <591>

This poster presented jointly with USP at AAPS meeting shows the new USP method for zinc as per <591> using Ion Chromatography which is highly selective and sensitive. Selectivity is achieved by separation and further improved with PCR reaction. Sensitivity and wide linear quantification limit make the new USP method ideal for QA/QC. Automated PCR delivery makes the overall method performance easy to validate.
