The Viscotek UV detector is sold as an addition to the Viscotek TDAmax to complete a Tetra Detector format, or as a standalone module for connection to other chromatography components such as the SEC-MALS 20.
- Excellent tool for the compositional analysis of co-polymers or protein conjugates
- Precise and accurate temperature control as the detector cell is housed in the same thermal chamber as the rest of the system
- Choose the most appropriate wavelength for your sample
- Unmatched baseline stability and data reproducibility
How it works
A pump such as the GPCmax, and some form of injection device, such as a manually actuated valve or autosampler, creates a flow of mobile phase through a UV detector flow cell.
With the TDAmax system, this flow cell is situated within the detector array housing itself.
Light from the UV detector is passed through the flow cell via fibre-optic cables. Compounds with a UV chromophore give a response on the detector, which is directly proportional to the concentration. The UV detector measures absorbance at the user-specified wavelength.
The OmniSEC software records the absorbance data as a chromatogram along with all the other data channels. This is then used to calculate concentration or conjugate data depending on the analysis settings in the software.
