Chemical reactions – the importance of accurate flow measurement

Chemical reactions – the importance of accurate flow measurement

Accurately measuring the rate of addition of liquid reagents is a critical consideration for many laboratories undertaking batch or flow chemistry reactions. When dispensing expensive chemicals or other fluids into a reaction, labs must ensure the right amounts are added as part of quality control. Without accurate flow measurement, too much or too little chemical can be injected into a reaction, resulting in adverse outcomes, expensive reagent overuse and safety issues. In fact, inaccurate flow measurement can mean the difference between profits and lost revenue.

Why is precise dn/dc measurement important?

Why is precise dn/dc measurement important?

Light scattering is a trusted detection method for measuring molecular weight and therefore a widely used tool for analyzing biopolymers, polymers and proteins by GPC/SEC. One of the most important parameters to ensure top quality light scattering data is the refractive index increment (dn/dc). Accurately determining the dn/dc value is vital because it is the link that translates raw refractive index data into sample concentration. The most accurate method of determining dn/dc is to use a stand-alone batch instrument, such as our HK series differential refractometer, and to take measurements at different concentrations.
