Contract notice: Supply of OP RDI - Atomic Absorption Spectrometer, OP RDI - supercritical fluid chromatograph with a PDA detector, OP RDI - SEC chromatograph with triple detection, OP RDI - Indoor ultracentrifuge rotors, OP RDI - Low temperature chamber for X-ray diffractometer
In the development of multi-component materials such as copolymers, triple detection is further improved upon by adding either a UV or PDA detector.
Triple Detection Standards comprise six sets of two standards each: one narrow and one broad.
For laboratories involved with characterization of natural and synthetic polymers, proteins or nanoparticulate materials, the company has published a 12-page booket comprising a series of technical articles to help practitioners of triple detection GPC/ SEC better understand and use the technology.
Combining the capabilities of traditional triple detection with new ultraviolet-viscometer and low-angle, light-scattering (LALS) options, the TDA measures concentration with a refractive-index (RI) or ultraviolet (UV) detector, or both.
Triple detection allows determination of absolute molecular weight, intrinsic viscosity, molecular size, and information on the conformation, structure, branching, and aggregation characteristics of the sample.

Supply and operational installation, including installation of the necessary software and hardware to the system controller, a gel permeation chromatography system (multi-angle light scattering detector, viscosity and RI detector) with triple detection (type: TDAmax GPC system with SEC-MALS 20 multi-angle light scattering detector) as well as the handing over of a German or English manual.
Triple Detection Standards (TDS) comprise six sets of two standards each, one narrow and one broad.
Triple detection is said to set the standard for GPC/SEC technology, and is said to be the preferred method for macromolecular characterization.
The compact and easy-to-use instrument can be configured as a high speed GPC with a triple detection system--including a viscometer, a light scattering and IR detector--or into a GPC + TREF system capable of performing both techniques and with a triple detector system also.
Triple detection systems, which employ a concentration detector, viscometer and light scattering detector operating in concert, are said to be the defacto standard for the characterization of natural and synthetic polymers and proteins in the petrochemical, specialty chemical, elastomer, adhesives, coatings and other markets.
