The ultimate in advanced detection for UPLC/UHPLC and APC separations

  • OMNISEC REVEAL ULTRA is compatible with UPLC/UHPLC and APC separations. 
  • Whether you want to perform UPLC-SEC, HPLC-SEC or both the REVEAL ULTRA can perform for you. Enabling method transfer from HPLC to UPLC using the same system, or for future proofing purchases. 
  • Complete flexibility in detector configuration. Only purchase the detectors which add value to you now, with the security that any detector you require in the future can be installed onsite.

Increased productivity, improved resolution, reduced sample consumption, reduced solvent usage

  • Faster run times mean 3 times the productivity from a single system!
  • Improved resolution allows you to see features hidden in standard HPLC-SEC systems
  • Up to 20 times reduction in sample loadings – saving precious samples.  
  • Consume up to 4 times less solvent – reducing disposal costs. 

More reliable measurements with market leading light scattering sensitivity

  • Measure low concentration samples with a highly sensitive and stable refractive index detector
  • Measure molecular weight of polymers as low as 200 g/mol!
  • Incredibly low injection masses for characterization by UPLC-SLS
  • 5ng PS105k in THF

  • Distinguish chemical changes by measuring absorbance across the full UV/Vis spectrum (190-900nm) using the photodiode array
  • All UV channels are recorded giving you the flexibility to choose what wavelength to use in post-processing

All systems can be fully serviced and supported onsite

  • No need to worry about shipping systems for service or support, all units can be fully serviced on site to ensure minimum downtime

How it works

Following separation of the sample according to its hydrodynamic volume the sample will pass through 1 or more detectors where its presence is recorded. OMNISEC REVEAL is a fully integrated multi-detection module which can contain up to 4 different detectors. 

The RI and UV detectors give information about the concentration of the components in the sample. The light scattering detectors respond to the intensity of light scattered by the sample which is related to molecular weight and also allows Rg of large molecules to be calculated. The viscometer measures the changing solution viscosity to calculate the intrinsic viscosity of the sample which is a measure of structure. 

Coupling the efficient sample separation of OMNISEC RESOLVE with the fully optimized, multi-detector, information-rich analysis delivered by OMNISEC REVEAL, Malvern Panalytical has produced a market-leading solution for researchers and formulators developing novel natural and synthetic polymers, pharmaceutical and biopharmaceutical products and foods.
