Autosamplers are necessary for laboratories that method a higher volume of samples employing a fuel and/or liquid chromatograph. Letting an autosampler to inject samples in to a chromatograph benefits in larger sample stability and a more effective chromatography method compared to injecting the samples by hand. For these causes, most labs select for autosamplers in place of stand-alone concentrators that want manual assistance.
