Ion chromatography in the philippines
WebWhen an IEX separation has been optimized using gradient elution, changing to a step elution reduces the total number of column volumes used for a separation. This speeds … WebCombustion ion chromatography (IC) measures total halogens (fluorine, chlorine, bromine, iodine) and sulfur in difficult to analyze solid, gas, and liquid samples. Determination of these analytes is essential because they are: Corrosive, which can damage industrial equipment, poison catalysts, and damage sensitive electronic components.
