13 Ways to Stop an Unseen Force from Disrupting Weighing
News Oct 03, 2015
Mettler Toledo has announced the publication of a new paper entitled “13 Ways to Eliminate Electrostatic Forces that Disrupt Weighing.” The article describes 13 different strategies to stop static and preserve accuracy, which can be particularly critical when dosing small amounts of potent, powdered substances.
Electrostatic charges have the capacity to alter weighing results by as much as a few hundred milligrams. On a day-to-day basis in a pharma or chemical lab, however, the interplay of static between an object and weighing cell tends to be more subtle. Without even realizing it, an operator can produce solutions with inaccurate concentrations. These poorly-produced solutions negatively affect downstream lab and production processes.
This new Mettler Toledo paper helps readers avoid these out-of-specification results with no- and low-cost fixes using everyday items and strategies to keep static from starting or help it dissipate, such as letting lab vessels rest after cloth-drying. It also discusses technological solutions that permanently eliminate the possibility of static affecting balance results.
