Different volatile carboxylic acids and sublimate salt have been investigated as ion competitors to optimize the separation of four common anions (phosphate, chloride, nitrate, and sulfate) by Ion Exchange Chromatography (IEC) with Evaporative Light Scattering Detection (ELSD) on a Hamilton PRP‐X100 (100×4.1 mm ID) column. We evaluated the effect of temperature on the response of inorganic anions by ELSD. The latter is especially strong for chloride and nitrate but for sulfate and phosphate the detector response remains essentially temperature‐independent in the temperature range studied.
