Experimental Guidelines - DWS Sample Preparation

 
 

V) Equilibration

 

After inserting the cuvette with the sample into the sample holder, wait 10-15 minutes so that the temperature of the sample is the same as the temperature of the thermal chamber. Note also that some samples require a significantly longer equilibrium time because the stress induced from filling the sample into the cuvette needs to relax. This effect is called thixotropie and is common for highly viscoelastic samples.
