Application

Proteomics

  • Low Abundance Protein Identification & Quantification
    • Complex Chemistry of Hydrophilic & Hydrophobic Samples
    • High Resolution
    • High-Throughput
Nano-XPLC can enhance the efficiency of quantification and qualification in proteomics

The innovative dual-core ultra-high pressure Nano XPLC greatly advances the MS application efficiency. The duration of regular nano LC analysis is about 20-60 minutes on average, the efficiency is limited when MS needs to wait till the equilibration procedure completed. Dual-core Nano XPLC allows the procedure for using dual binary gradient HPLC which can continuously pass analytes one after another to Mass Spectrometer, so MS works with one sample and when it is done, valve shifts and MS immediately works on the sample.

  • Step 1
    • First Binary Gradient System: analyte injected , separated, processed to MS
    • Second Binary Gradient System: Preparing column and sample injection to be ready for run
  • Step 2
    • First Binary Gradient System: After the run ,then it proceeds to prepare column and equilibrating then being conducted valve to switch to next run
    • Second Binary Gradient System: Swithes to MS and the analysis started.
  • Step n
