GPC / SEC · Multi-detector
Past. Present. Future-proof.
Haiku Instruments is building a quad-detector GPC/SEC system. Refractive index, UV-Vis, light scattering and differential viscometry run in one instrument, from one injection, for absolute molecular weight and structure.
- LS
- DP visc
- dRI
- UV-Vis
Four detectors. One injection.
Each channel answers a different question about the same slice of sample. Together they remove the dependence on a conventional calibration curve.
Concentration
Mass at every slice, via dn/dc. The universal reference channel.
Composition
Chromophore content across the distribution for copolymers and conjugates.
Absolute Mw
Molar mass from scattered light, independent of column standards.
[η] and structure
Intrinsic viscosity, Mark-Houwink parameters and long-chain branching.
Legacy support
Bring what you have. Add only what you need.
Know that it will not reach "end of support" because the manufacturer wants to sell you a new one that does the same as the old one, just with a new exterior case.
How we support older systemsPricing
