ViscoStarTM Differential Viscometer Detector
Wyatt Technology?s ViscoStarTM viscometer, is an on-line chromatography detector for determining specific and intrinsic viscosities. The ViscoStar has at least 2X the signal-to-noise of any product available on the market as well as a proprietary Transducer Protection System (TPS) that prevents accidental damage to sensitive transducer membranes.

The ViscoStar has at least 2X the signal-to-noise of any product available on the market as well as a proprietary Transducer Protection System (TPS) that prevents accidental damage to sensitive transducer membranes.
This new product also includes novel features found in no other viscometer. The ViscoStar has a software-based pulse dampening correction algorithm that virtually eliminates pump pulses, and the product offers precise temperature control from 4°C to 60°C--the below ambient range of which is not available anywhere else.
The ViscoStar comes standard with 18 Bit A/D resolution, Ethernet and USB communications, and a razor-sharp LCD based user interface. The ASTRA software that comes with it includes not only all of the viscosity calculations required, but a complete column calibration module, as well, for customers who want to perform this kind of analysis.
The ViscoStar is compatible with all HPLC systems.

Extraction of 40 PFAS Compounds from Soil and Tissue
December 6th 2024PFAS have been shown to cause health issues in humans, which means monitoring environmental solid samples, such as soil and tissue, is critical. This application note details the extraction of 40 spiked PFAS compounds from soil and tissue following EPA Method 1633. The automated extraction was less than 10 minutes per sample and yielded acceptable recoveries and RSDs without carryover in the system. The EDGE PFAS is an ideal option for laboratories that want to automate their PFAS extractions of solid samples.
