Determination of Nucleotides by Liquid Chromatograpy with a Phosphorus Sensitive Inductively Coupled Plasma Detector.
Abstract
Quantitative analysis of 100 microliters nucleotide samples is accurately performed by analyzing total phosphorus concentration using an inductively coupled plasma (ICP) system. A single calibration using Na2HPO4 (aq) is useful for all nucleotides. A detection limit of 750 ng of phosphorus is determined with an RSD of 4.5%. High performance liquid chromatography (HPLC) is used to separate mixtures of nucleotides on an anion exchange column using acetate buffers. The ICP is used as a selective detector by observing P(I) emissions at 213.6 nm. A Babington nebulizer which is used to aspirate the high percentage salt solutions with 6% efficiency is described.
