Answer 2

Answer:

Semi-micro analysis refers to a sample size of 2) 10mg-100mg

Explanation:

• The semi-micro analysis is the analysis of substances with microscale mass. Samples for this type of analysis typically have a mass of 10mg-100mg and a volume of 1.0 mL.
• These techniques work with very small sample volumes, so contamination must be avoided. Semi-micro analyzes are often categorized as regular qualitative analytical techniques, and these techniques are easy to use.
• They are relatively cheap. However, the accuracy of the final result is affected by impurities in the sample. Therefore, samples should be handled carefully and cleanly.

Absolute sample volume: Macro analysis: 0.1 to several grams.
Semi-micro analysis: 10-100 mg.
Trace analysis: 1-10 mg.
Ultratrace Analysis: < 1mg
