Rapid Separation LC (RSLC) Autosampler

The UltiMate® 3000 Rapid Separation Autosampler injects sample volumes up to 100 μL at pressures up to 800 bar (11,600 psi). The in-line, split-loop injection principle provides highly accurate and precise delivery of the sample with ultralow carryover. The wide injection-volume range makes the module suitable for both UHPLC and conventional HPLC applications.

  • Peak area precision typically <0.15% RSD for 5 μL injections
  • Superior injector linearity of r2 >0.9999 (5–90 μL) due to high-precision drive mechanism
  • Wide injection volume range from 1–100 μL (default configuration) for maximum injection flexibility
  • Optional injection volume ranges of 0.2–25 μL, 1.5–200 μL, and 1.5–500 μL available
  • Low gradient delay volume of 140 μL (default configuration) or 50 μL (with 25 μL sample loop)
  • Volumetric accuracy better than ±0.5% for 20 μL injections for easy method transfer
  • Supports well plates and short injection cycle times for high-throughput applications
  • Sample thermostatting for optimal protection of thermally-sensitive analytes (WPS-3000TRS)

The UltiMate 3000 Rapid Separation Autosampler offers minimal gradient delay and low extracolumn volume, which provide high efficiency separations and short chromatographic run times. It is strongly recommended for ultrahigh-pressure, high-throughput, and high-resolution applications, and is available in non-thermostatted (WPS-3000RS) and thermostatted (WPS-3000TRS) versions.
