Evaluation of disposable cartridges for trace enrichment from aqueous solutions

摘要: Selected aromatic hydrocarbons, phthalate esters, and food, drug cosmetic (FDC however, the latter exhibits greater capacity for FD&C dyes, which have breakthrough volumes that are a function of pH. Both cartridge types show small amount analyte leakage during trace enrichment step, is measured by monitoring effluents presence 14C-labeled solute. Two PRP-1 cartridges connected in tandem reduce activity effluent approximately one half.
