Autosamplers are necessary for laboratories that process a higher volume of samples using a fuel and/or fluid chromatograph. Allowing an autosampler to insert samples in to a chromatograph effects in greater sample reliability and a better chromatography process compared to injecting the products by hand. For these causes, many laboratories pick for autosamplers as opposed to stand-alone concentrators that require guide assistance.
