As the ultraWAVE allows to set the conditions of the complete stainless-steel chamber, the mixture of different samples and reagents can be used simultaneously ensuring the same temperature and pressure for all of the samples. Sample batching and method development are no longer required. A reference material can also be processed with the other samples to ensure true digestion quality control in the same run. The enhanced temperature and pressure (300°C and ~200 bar), and its capability to perform digestions even with very aggressive media, such as aqua regia, offer a greater digestion on virtually any matrix. As the digestion quality is directly affected by the achieved temperature, the ultraWAVE provides the complete recovery of the target elements, low residual carbon and acidity, also maximizing the performance of the analytical instrument.
