1. Instrument Calibration: Regular calibration of measurement instruments is crucial. Using standard reference materials can help ensure accuracy. 2. Controlled Environment: Maintaining a controlled environment can minimize the impact of temperature, humidity, and vibrations. 3. Advanced Techniques: Employing advanced measurement techniques, such as cryo-electron microscopy or high-resolution AFM, can reduce errors. 4. Training and Best Practices: Ensuring that operators are well-trained and follow best practices can minimize human errors.
