The combination of infrared and microwave radiation to quantify trace elements in organic samples by ICP OES

► Sample mass up to 1 g was completely digested using the IR-MW system. ► The layout of IR-MW is a simple arrangement with a commercially-available IR lamp. ► The same quartz vessel from the MW oven is used in the IR lamp. ► The IR-MW is a promising alternative to digest organic samples for trace analysis.
