BACK

Trek offers a unique, small, and portable Q/m analyzer which utilizes the "draw-off" toner transfer method to yield repeatable high accuracy toner charge measurements. The Trek Model 210HS-2B Charge-to-Mass Ratio (Q/m) Test System* is used to quickly and accurately determine the charge-to-mass ratio characteristics of both single and dual component electrophotographic toners and other charged particulates. Interchangeable mesh filters accommodate various sizes of charged particles. The system is highly portable for use directly on the production line as well as in the laboratory.

The Trek Model 210HS-2B system employs a unique specimen separation and transfer technique which avoids the creation of measurement errors due to the undesired additional charging of the toner as caused by the rapid air movement associated with "blow-off" type measurement systems.

The Trek Model 210HS-2B is configured as a separate main indicator unit, a plug-in sample cell unit, and a plug-in absorption nozzle unit to allow for different configurations in response to various user applications. When stronger suction is required, such as for single component toners, an optional external pump is used which is controlled by the Main Indicator Unit.
