Arginine for stabilization?

Often, pharmaceutical formulations contain therapeutic proteins at relatively high concentration. Under such conditions, the stability of the protein as well as the formulation overall is of significant concern. Great effort is invested in optimizing stability, and particular attention goes to the choice of buffer components. Various components might form part of the ‘final’ recipe including [...]

Zetasizer WT: An upset detector for water treatment plants

Just last month we launched the Zetasizer WT, an on-line zeta potential measurement system designed specifically for water treatment plants, following years of working closely with partners in the water industry.  If you missed the launch event, you can catch up with the recording here. While the benefits of using zeta potential measurement in labs [...]

Scattering volume in dynamic light scattering – how to find it?

Every once in a while the issue of “How large is the actual scattering volume?” comes up in dynamic light scattering. To understand the background let’s look at the optical design inside the experimental setup. This design differs between different configurations, and there are two main configurations of the Zetasizer: the Non Invasive Back Scattering or [...]

The spice is right? Check your particle size!

Variety is the spice of life.  And variety is the constant theme of my webinars.  We’ve looked this year at absinthe (which makes the heart grow fonder) louching, the rheology of cheese and mayo (another cheesy subject), coffee (think of your own pun), and now the particle size of spices continuing a sort-of strange food [...]
