Follow this Equipment

Provides increased chromatographic resolution, reproducibility, and sensitivity for sample-limited, information-rich, nano-scale MS analyses.

The nanoACQUITY UltraPerformance LC® (UPLC® ) System is designed for nano-scale, capillary, and narrow-bore separations to attain the highest chromatographic resolution, sensitivity, and reproducibility.  
  
Direct nano-flow offers significant improvements over conventional nano-flow separations technologies. You’ll see improved peak capacity and peak shape, and increase the number of components that can be detected per separation.  
  
The system’s 10,000 psi operating pressure capability allows for superior high-peak capacity separations by operating longer columns packed with sub-2 micron particles. It is optimized for high-resolution identification and 2D-LC separations at precise nano-flow rates:  
  
The nanoACQUITY UPLC System provides solutions for biomarker discovery and proteomics applications, for protein identification and characterization.

  • Stand-alone nanoACQUITY UPLC console provides easy instrument control.  

High Peak Capacity Separations  

In the data below, we see a separation of protein digest standards on columns packed with 3.0 mm particles (top), compared with the same experiment using 1.7 mm BEH particles (bottom). Running the 1.7 mm column produces higher peak capacities, narrower and highly concentrated peaks, and more MS information.  

  

Direct Loading and Trapping  

The chromatographic separation of a tryptic digest of 200 fmol yeast enolasse using (A) direct loading and trapping onto the analytical column and (B) sample trapping followed by separation on an analytical column. Both methods demonstrate the ability to efficiently resolve the same peptide components, revealing virtually identical chromatographic profiles.

Reproducible Nano-Flow Separations  

In this tryptic digest of human cells (n=6 over a 12-hour period), it is possible to see retention time reproducibility usually achieved at analytical scale flow rates. Using shallow gradient conditions, there is a change of 0.3% B/min over two hours. Changes in retention time between comparable samples are due to changes in peptide structure (an indication of changes in protein expression).  

  

Heating and Trapping Module  

In the nanoACQUITY UPLC System’s Heating and Trapping Module, the analytical column is housed in an extendable arm that delivers analytes to the source of the mass spectrometer. It is contained in a thermally controlled sleeve, which, when combined with the minimized dead volume of the system, leads to improved peak shape, peak resolution, and reproducibility for HPLC and UPLC separations. A trapping column can also be easily added to desalt and pre-concentrate larger sample volumes.  

  

Binary Solvent Manager  

The nanoACQUITY UPLC System’s Binary Solvent Manager (BSM) features responsive flow sensors, optimized tubing, and sophisticated algorithms enable flow rates from 200 nL/min. An automated vent valve facilitates rapid priming and purging and solvent select valves permit alternate solvents for each pump. Two high pressure streams, in 25 µm I.D. tubing, converge in the tee. The system volume from the site of gradient mixing in the tee to the trapping column is <1 µL.
