Page 12 II. Product description 2.1.1 Measurement Charged colloids and particles of a size > 1nm can attract oppositely charged ions from the surrounding water. Separating these so called counterions from the particle creates a measurable potential difference. If such ion separation is achieved through a liquid flow, the potential is called streaming potential with the unit After a sample has been filled into the Mütek™...

V. Measuring 5.4 Sample preparation For stock systems including both colloidally dissolved material and solid particles, different ways of sample preparation will give different data on the charge condi- tions prevailing in a sample (see 4.4.3 "Sample specifi- cation", page 24).
