Determination of inorganic anions in natural water by microcolumn ion chromatography with on-column enrichment.
An on-column enrichment method was developed for the rapid determination of inorganic anions in natural water. The system was assembled from a syringe pump, a six-port switching valve with a sample-enrichment loop, a separation column and a UV detector. The enrichment efficiency of the system was tested by using inorganic anions as samples. The limits of detection were between 0.6 and 7.7 micro...
متن کاملFast ion chromatography of inorganic anions and cations on a lysine bonded porous silica monolith.
A 0.46 cm x 10.0 cm silica monolith column was modified through the in situ covalent attachment of lysine (2,6-diaminohexanoic acid) groups. Due to the zwitterionic nature of the resultant stationary phase, the modified monolithic column contained both cation and anion exchange capacity. In the case of cation exchange, the capacity was found to be relatively low at between 5 and 6.5 micromoles ...
متن کاملIon Chromatography of Common Anions by Use of a Reversed-phase Column Dynamically Coated with Fluorine-containing Surfactant
A method with unusual selectivity has been developed for determination of common anions such as chloride, bromide, nitrite, sulfate, phosphate, and iodide. The method uses with reversed-phase columns (graphite carbon and ODS), coated with fluorine-containing surfactant, and conductivity detection. A graphitized carbon column was selected for this study because of its high chemical stability, re...
متن کاملDetermination of anions of milk by ion chromatography
The anions of milk have been successfully analysed by ion chromatography coupled with suppressed conductivity detection. With an appropriate sample preparation (ultrafiltration alone, or combined with dry mineralization), this method enabled simultaneous identification and quantification of chloride, phosphate and citrate ions with good repeatability (relative standard deviations of about 1%). ...
