Eksigent - expressLC 800
experiment with eight LC methods in parallel and expedite methods development
With eight completely independent channels and up to eight different gradients, the ExpressLC-800 allows parallel evaluation of up to eight HPLC methods simultaneously. By combining fast flow rates with eight channels, the system delivers up to 10 times the sample throughput using less that 1/10th of the solvent. An intuitive software interface means that a single operator can run the instrument, and we’ve engineered the system so methods can be easily transferred to conventional HPLC with negligible re-optimization.
The eight-column ExpressLC-800 system multiplexes Eksigent’s fast and reliable capillary chromatography technology to deliver extraordinary analytical speed and throughput. The ExpressLC-800 offers true parallel HPLC with independent mobile phases, injectors, UV detectors, and rapid, precise adjustment of flow rate via Microfluidic Flow Control (MFC) technology.

Features of expressLC 800
- Offers true multiplexed HPLC with independent mobile phases, injectors, and UV detectors.
- With a footprint little more than that of 2 conventional HPLC systems, the ExpressLC-800 provides dramatic savings of laboratory bench space.
- No positive displacement pumps or large volume mixers to waste time forming gradients.
- Fast re-equilibration with a void volume of only 300 nL.
- Monitor analytes of interest using a low dispersion, microfabricated 45 nL flow cell with array-based UV detection.
- Optimized for 300 µm i.d. columns at flow rates of 1 to 30 µL/min.
- Microfluidic Flow Control (MFC) technology delivers rapid, precise adjustment of flow rate.
- In-line flow meters actively measure the actual flow rate of each mobile phase and provide immediate adjustments to deliver an accurate, consistent and precise gradient.
