Chemical Resolution


An analytical technology's chemical resolution describes the degree of detail that can be achieved in measuring the presence of molecules. This concerns both selectivity – ability to distinguish between different molecules – and sensitivity – ability to detect molecules in small amounts – of the technology. Mixtures, for example, may consist of many compounds with molecules ranging in concentration from a few ppt (parts per trillion) to percents. In particular in life science and nanotechnology applications even single molecule detection is relevant.
