Autosampler. An autosampler is commonly a device that is coupled to an analytical instrument providing samples periodically for analysis. [1] An autosampler can also be understood as a device that collects samples periodically from a large sample source, like the atmosphere or a lake, for example. Autosamplers enable substantial gains in ...
