1260 Infinity II High-Temperature Evaporative Light Scattering Detector
The 1260 Infinity II High-Temperature Evaporative Light Scattering Detector (HTELSD) is capable of detecting very low concentrations of high-molecular-weight polyolefins (polyethylene and polypropylene) at elevated temperatures. The need to analyze ultrahigh-molecular-weight polyethylene (UHMWPE) requires a new detection technique that offers a high level of baseline stability in order to reproducibly detect and permit accurate analysis of this part of the molecular weight distribution.
High-temperature ELSD is ideal for polymers that require lower column loading to reduce the risks of shearing and degradation. Considerably more sensitive than refractive index detectors, there are no negative or interferring peaks to compromise accurate analysis.
