A differential refractive index detector (DRI) can be used to determine the concentration of samples which otherwise do not indicate absorption in the UV range. But for process applications, standard DRIs do not have the dynamic range needed to quantify sample concentrations that are usually higher than in routine analytical tasks.
In response to an OEM customer reequest - Testa Analytical designed a DRI kit that was specifically made to target this kind of job. An adapted model of this kit has helped boost the market penetration of a firm that delivers innovative technology solutions for both control and optimization of polymerization procedures.
For this specific client, Testa Analytical’s DRI kit has demonstrated itself in several installations to consistently quantify target analytes across a broad concentration range in harsh process environments with the highest accuracy and reliability.
