The May-June issue focuses on pump systems, pipes and valves; sample preparation; centrifuges; nanotechnology; power generation; ion chromatography; and life sciences. What’s the difference between High Pressure Liquid Chromatography (HPLC) and Ion Chromatography (IC)? What are the capabilities and limitations of each technique? Knowing these differences can actually make a huge difference. As a proven, robust and highly versatile technique, IC can help HPLC users extend their analytical capabilities tremendously. In our article on page 24, Metrohm compares the two methods systematically, focussing on the strengths of ion chromatography
