What is the suitable size range of a sample for micro analysis?

• A. 1-10 mg
• B. 10-100 mg
• C. 100-200 mg
• D. 200-300 mg

Answer: (B)

Microanalysis typically involves the examination of very small quantities of a sample, usually in the range of micrograms or milligrams. This technique is essential when only a limited amount of material is available or when the analysis requires a high degree of sensitivity. The most suitable size range for micro analysis is usually considered to be between 1 mg and 10 mg. This is due to the fact that techniques used in microanalysis often require small samples to minimize contamination and maximize analytical sensitivity. Within this range, methods can effectively determine the composition and structure of the sample, allowing for accurate assessments without the need for larger amounts of material. The choice of 10-100 mg mentioned in your answer aligns with general analytical practices rather than specifically microanalysis, as it tends to deal with larger sample sizes which are more appropriate for standard analytical methods rather than the highly sensitive and precise requirements of microanalysis. Therefore, the best characterization of microanalysis is captured by the smaller sample size range.
