An autosampler is commonly a device that is coupled to an analytical instrument providing samples periodically for analysis. 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. An autosampler is commonly a device that is coupled to an analytical instrument providing samples periodically for analysis. 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 productivity, precision and accuracy in many analytical scenarios, and therefore are widely employed in laboratories. An autosampler normally consist of a robotic device that can either bring the sample to a sampling station, or bring a sampling device to the sample that stays on a tray (or carousel) along with other samples.
