Overview
OMNISEC REVEAL ULTRA is designed to bring integrated advanced detection to the high resolution separations offered by UPLC-SEC. This unique system improves sample resolution, increases system productivity, reduces sample and solvent consumption.
Use the OMNISEC REVEAL ULTRA to study the impact of protein oligomerization, aggregation and conjugation on activity and efficacy in academic research and biopharmaceutical development.
Relate a polymer’s molecular properties to its bulk characteristics in a wide range of applications, from additive manufacturing, to paint and coatings industries to the manufacturing of food additives and pharmaceutical excipients.
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!

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.
