This instrument is very helpful and workable.

To directly determine the molecular weight is a difficult job to work on. This instrument enabled my lab to easily determine the molecular weight of starch, cellulose, and chitin with reliable data. The operation of the instrument needs some training, and fundamental understanding on the measurement principles. I used the SEC/MALLS/RI analysis system comprising a SEC system (1260 Infinity, Agilent), a multi-angle laser light scattering (MALLS) detector (DAWN HELEOS-II, λ = 658 nm, Wyatt Technology), and an RI detector (RI, Optilab T-rEX, Wyatt technology).

Application Area: Molecular weight of polymers

One of the best analytical instruments I ever used in my 25 years working.

As we were starting characterization of our polymers depressants and collectors, we needed to get instruments that will give us most information for us to understand how each property will affect the quality and performance of our product, as part of continuous improvement. We bought the Wyatt triple detectors of which RI was one of them. The service we got from the company was very good starting from installation of the instruments. Doing operational qualification and performance qualification of the detectors was excellent. They sent a professor to help us with that training on the system for data analysis. After sale care was also excellent - when we had just started we had problems in understanding some information and data we got from the systems. We sent all the information to Wyatt head office and within 24 hours we got response. When one of the detectors had a breakdown we shipped to the US and within a very short time it was back working properly.

Application Area: Molecular weight analysis for depressants. Together with the LS detector we are able to do conformat

Used daily in our lab- we consistently rely on it!

The Optilab T-rEX is the perfect complement to the DAWN HELEOS II to supply reliable and accurate concentration information for molecular weight measurements. Having an RI detector in our flow path is also quite handy if our samples have weak or no UV absorbance.

Application Area: Measure concentration of downstream SEC samples

I could not recommend Wyatt Technology more highly!

Highly sensitive and reliable system that provides exceptional accuracy and precision. Sales support at Wyatt is one of the best in the analytical instrument sector.

Application Area: Analysis of Molecular Weight Distribution in Linear Polysaccharides
