Solvent injection

WebCheck your column installation distance! When performing splitless injections, it is not uncommon to witness a tailing solvent peak, given the large amount of solvent introduced onto the column over a relatively long period of time. For split injections, however, only a small portion of the solvent loads onto the column and it occurs very quickly. WebInjector and Injection Solvents. The injector rapidly introduces the sample into the system with minimal disruption of the solvent flow. HPLC systems currently use variable loop, fixed loop, and syringe-type injectors. These are activated manually, pneumatically, or electrically.
