Choosing a particle sizer has never been more difficult. There are several different particle sizing techniques to choose from and variations within each technique. Often manufacturers claims of specification and performance have become inflated, particularly confusing for the first time buyer. Our new guide discusses how different applications are often best served by different particle sizing techniques and is written by experts to provide an informed and unbiased guide to help you choose your next particle sizing system.

The refractive index (RI) detector is the most common detector in gel permeation chromatography/size-exclusion chromatography (GPC/SEC). The advantage of this universal detector is that it detects everything; the disadvantage is that it detects everything. A recent instalment of LCGC’s “Tips & Tricks” feature offers some advice when working with RI detectors.

Determination of concentration of samples which do not show absorption in the UV Range can be accomplished by using a differential refractive index detector (DRI). For some process applications however, standard DRI's lack the dynamic range required to measure sample concentrations that are typically higher than in common analytical tasks. Learn more about how we developed an adapted DRI detector to fulfil this application for a polymerisation monitoring customer.

Let There Be Light: Characterizing Physical Properties of Colloids, Nanoparticles, Polymers & Proteins Using Light Scattering
This book is about characterizing the physical properties of submicron particles such as colloids, nanoparticles, polymers and proteins when suspended or dissolved in liquids. Characterization includes determination of size, charge (zeta potential), and molecular mass. Detours into rheology of dilute solutions and suspensions using dynamic light scattering and charge on macroscopic surfaces using phase analysis light scattering are included because these same techniques are used in size and charge characterization of fine particles.
