Hybrid & Next-Generation Autosamplers: Agilent’s Feed Injection Innovation
Agilent’s innovation in autosampler technology shines through its Hybrid Multisampler Series, comprising the 1260 Infinity III and 1290 Infinity III Hybrid Multisamplers featuring dual injection modes. In classic flow-through mode, the mobile phase flows through a preloaded sample loop, as in traditional injection systems. The distinguishing capability, however, is Agilent Feed Injection mode: here, the sample is continuously infused directly into the mobile phase, mitigating issues from strong solvent effects (like peak distortion) by mixing sample and mobile phase at injection time. This hybrid technology is particularly valuable when analyzing samples in strong solvents—a common challenge in pesticide analysis, PFAS detection, and battery electrolyte characterization. Both the 1260 Infinity II Hybrid Multisampler and 1290 Infinity III Hybrid Multisampler support this mode and assist in preserving peak shape and sensitivity without extra sample prep.
