Fluoride, chloride, bromide, nitrite, nitrate, phosphate and sulfate are separated with a mobile phase (3.2 mmol/L Na2CO3 and 1.0 mmol/L NaHCO3) across a Metroselp A Supp 5 anion exchange column. The detection is based on a conductivity measurement. The system uses an ion suppressor for the reduction of the baseline and an increase in the sensitivity. <a class="download-link" href="t3://file?uid=197820" target="_parent">User regulation</a></p> Content
