Sample injection methods in high-performance liquid chromatography (HPLC) can have an impact on reproducibility, throughput, sample and solvent use, carryover and more. Due to the importance of this step in the HPLC process, more laboratories are turning to automated sample injection methods to overcome the limitations of manual injection.
HPLC autosamplers greatly improve the precision and throughput of HPLC processes, and these modules have grown more advanced over the years, with capabilities for temperature control, sample dilution, overlapping injections for faster cycle times, and compatibility with ultrahigh-performance liquid chromatography (UHPLC).
There are a range of autosamplers available for HPLC with differing designs, specifications and features, and selecting an HPLC autosampler should involve assessing these factors in relation to the requirements of your application. This HPLC autosamplers buyer’s guide breaks down key things to consider when shopping for an autosampler.
