We know that electronic scales, mechanical scales, balances, and other tools are commonly used for weighing, and the need to eliminate human error and obtain fast and accurate measurements has created an insatiable demand for precision weighing balances. However, these balances do not always give accurate results because the environment and other external factors can affect them. A static charge is an example of a limiting factor.

    Ideally, the positive and negative charges in an object are in equilibrium or equilibrium. When this balance is disrupted, static charges begin to build up. This imbalance occurs when objects touch or rub against each other, causing friction and electron transfer. Note that while insulators don't allow electrons to flow and can't charge, conductors are easily charged but can transfer charge to another object. In laboratories where precision and analytical balances are widely used, electrostatic charges can be generated when: cleaning or wiping down laboratory equipment, handling weighing pans and weighing boats, and wearing protective gear.

    How does static charge affect precision weighing? The electrostatic charge constitutes electrostatic force and electrostatic field. The electrostatic force is responsible for the movement of dust particles and even small objects, while the electrostatic field causes the attraction or repulsion of the particles. As a result, high electrostatic charges can attract unwanted particles into laboratory samples, leading to contamination, weighing errors, and inaccuracies.
