Filter Testing

Filter testing efficiency

The AccuSizer liquid particle counter is used to test a wide range of filters. This may involve using two sensors upstream and downstream of the filter in order to calculate the efficiency at given size ranges. A common calculation used for filter testing is the beta ratio:

Pssnicomp - Equation

Optimum filter replacement conditions

Other customers place the AccuSizer system in the process and at point of use to determine optimum filter replacement conditions and to protect against upset conditions that are detrimental to product quality and yield, such as monitoring CMP slurries in the microelectronics industry.

Liquid Filter Testing

What is Liquid Filter Testing Filtration is the process of separating solids from fluids. In the case of liquid filtration testing, the goal is to remove solid particles from a liquid. The original fluid is called the feed and the fluid that passes through the filter is called the filtrate (as shown right). Liquid Filter…
