270 Dual Detector |
 |
 |
The Viscotek model 270 detector is the ideal building block for a modular advanced GPC/SEC system. It can be specified as a dual detector (viscometer plus light scattering) or as a single detector, either viscometer or light scattering.
In its full Dual Detector format the 270 contains a powerful differential viscometer detector and the advanced low angle light scattering detector. When used in conjunction with an RI detector, the triple detection system provides advanced chromatography where each detector gives complementary information on the molecule being analyzed. The further addition of a UV detector provides a wealth of additional compositional data particularly when the optional Photodiode Array (PDA or DAD) is used to make spectral measurement of all wavelengths simultaneously.
Its compact size, coupled with configuration flexibility, also makes the 270 an ideal instrument for upgrading any existing conventional GPC/SEC to a full triple detection system. |

 |
The 270 dual detector can house one or both of:
 |
 |
Light Scattering Detector
The powerful light scattering detector has two independent measuring points. Low Angle (LALS) and Right Angle (RALS) to give easy measurement of absolute molecular weight of any size of molecule without corrections or extrapolation. |
| |
|
|
Differential Viscometer Detector
The 4-capillary differential viscometer provides a direct measurement of intrinsic viscosity and allows for the determination of molecular size, conformation and structure. |
More information
Application communication: Structural differences in modified starches
The Viscotek triple detection system provides a convenient and rapid way to characterize starches and modified starches. The instrument allows determination of molecular weight and molecular size in a single run using normal conditions and sample concentrations. The IV and size data allow differentiation between molecules of differing structures. The technique is equally applicable to other polysaccharides and all other synthetic or natural polymers such as proteins and DNA.
