Electrostatic charges during weighing pose a significant challenge. Electrostatically charged samples or containers can be difficult to weigh. Static charges can cause unstable balance readings and measurement drift, leading to slow and inaccurate weighing results. Understanding what causes electrostatic charges during weighing, and how to avoid or eliminate them, is critical to avoiding disruption to weighing processes.
This white paper covers everything a balance user needs to know about electrostatic charges during weighing:
A negative charge on the measuring flask and a positive charge on the balance housing cause a force to be exerted between the balance and the vessel. The vertical component of this force adds to the weight of the flask and influences the weighing result.
The effects on the weighing accuracy could be:
State-of-the-art XPR analytical balances simplify the handling of static samples, ensuring the highest accuracy and most reliable weighing results. They are equipped with Automatic Static Detection technology - StaticDetect™ - a patented innovation to help balance users avoid weighing problems caused by electrostatic charges.
