- Differential Viscometer GPC/SEC detector
- Product Detail
- Company Profile
- Within a GPC/SEC Chromatography system, a viscometer allows use of a universal calibration. Molecular weights obtained with this method are therefore independent of the polymer standards used to build the calibration and can be considered to be close to absolute values. Also, a viscometer will allow determination of further molecular parameters giving insight about the physical structure of the investigated polymer and even opening the gate to determination of branching parameters. All viscometers for GPC/SEC currently on the market, base their principle on the measurement of the differential pressure across a capillary network. TESTA has been able to dramatically reduce the noise level and increase sensitivity by more than an order of magnitude compared to any viscometer available. This allows usage at much lower flow rates than it has been possible. Detection of lower molecular weight and at lower concentration are now also possible. Semi-micro applications are currently easily reached.
