What the System Measures

The combined OMNISEC RESOLVE and REVEAL GPC/SEC System provides absolute molecular weight, intrinsic viscosity, concentration, and conformational data in a single run. This eliminates the need for calibration standards, improving accuracy and confidence in results.

OMNISEC RESOLVE – The Chromatography Module

OMNISEC RESOLVE integrates four key components into a single unit:

Pump: Delivers a flow rate range of 0.01–10 mL/min with low pulsation (0.15% at 1 mL/min in water), ensuring stable baseline signals.

Degasser: Features a low-volume (960 µL) design for rapid solvent exchange, enhancing system productivity.

Autosampler: Accommodates up to 192 samples, with temperature control from 4°C to 60°C, suitable for both vials and 96-well microtiter plates.

Column Oven: Controls temperatures up to 65°C, supporting up to six analytical columns for optimal separation conditions.

This integrated design minimizes baseline noise and enhances measurement sensitivity, particularly for low-concentration or low-molecular-weight samples.

OMNISEC REVEAL – The Detector Module

OMNISEC REVEAL is an advanced, fully integrated, temperature-controlled multi-detector module that includes:

Refractive Index (RI) Detector: Highly sensitive and stable, enabling accurate concentration measurement, even for low-concentration samples.

UV/Vis Photodiode Array (UV-PDA) Detector: Measures absorbance at any wavelength from 190 to 900 nm, providing versatile detection options.

Light Scattering Detectors (LALS & RALS): Deliver market-leading sensitivity, allowing measurement of molecular weights as low as 200 g/mol and injection masses as low as 100 ng, for highly reliable results.

Viscometer: Features automated balancing for precise intrinsic viscosity measurements, with a user-exchangeable capillary bridge to minimize maintenance.

The fully temperature-controlled design improves detector stability and overall sample characterization, ensuring optimal performance for sensitive applications.

OMNISEC Software

The OMNISEC software suite provides:

Unified instrument control, data acquisition, and analysis.

Calculations for molecular weight (Mn, Mw, Mz), polydispersity, radius of gyration (Rg), intrinsic viscosity, and Mark-Houwink parameters.

Support for automated, unattended operation to streamline workflows.
