| | | Rapid Separation Autosampler |
| The Rapid Separation Autosampler is an essential component of the UltiMate® 3000 Rapid Separation LC System and can be operated at ultrahigh backpressures. Unlike other UHPLC autosamplers, the Rapid Separation Autosampler can inject sample volumes up to 100 µL at pressures up to 800 bar (11,600 psi). A patented rotor seal design ensures very long life times of the rotor seal and stator even when working at continuously high pressures. The wide injection volume range of the RS sampler makes the module suitable for both UHPLC and conventional HPLC applications. For highest separation quality, the sampler offers minimal gradient delay and low extracolumn volumes which mean high efficiency separations and short chromatographic run times. The sampler uses an in-line, split-loop injection principle where the needle and sample loop are integral parts of the high-pressure fluidic path. This ensures 100% transfer of the sample volume and virtually eliminates carryover between sample injections. The UltiMate 3000 Rapid Separation Autosampler is strongly recommended for ultrahigh pressure, high-throughput and high-resolution applications. Supports an injection volume range from 0.001 to 100 µL (settable range); 2500 µL option available Well plate compatible sample trays paired with low injection cycle times (<15 s for 5 µL) support high throughput LC and LC-MS applications The UltiMate Rapid Separation Autosampler have only 3.1 µL of extracolumn volume to minimize dispersion during injection. Combination of a high-precision drive mechanism and a low gradient delay volume (100 µL standard, 40 µL with micro loop) routinely delivers injector linearity values of r2 >0.9999 at 5-80 µL injection volume Volumetric accuracy better than +0.5% for 20 µL injections guarantees consistent results between instruments and easy method portability Peak area precision is typically <0.15% RSD for 2 µL injections
