What can cause fluctuations in analytical balance?

Answer 1

There can be many sources of error for analytical balances. Some of these include:

1. Air Currents / Drafts

2. Adsorptive layer of moisture on the sample

3. Electrostatic forces

4. Magnetic forces

5. Air buoyancy

6. Improper calibration

7. Temperature changes

8. Not level

Answer 2

Fluctuations in an analytical balance can be caused by factors such as air currents, temperature changes, vibrations, and improper handling or placement of the balance. It is important to ensure that the balance is placed on a stable surface, away from sources of disturbance, and in an environment with minimal air movement to minimize fluctuations. Regular calibration and maintenance can also help to reduce fluctuations in the balance.
