Chromatography is used for the purification of

Options

A. very reactive
B. available in minute quantities
C. present in abundance
D. highly electropositve

Explanation

**Step-by-Step Solution:**

1. **Understanding Chromatography**: Chromatography is a technique used to separate and purify components of a mixture based on their different affinities to a stationary phase and a mobile phase.

2. **Purpose of Chromatography**: The primary purpose of chromatography is to separate and analyze compounds that are present in very small quantities. This makes it an essential technique in various fields, including chemistry, biology, and environmental science.

3. **Application of Chromatography**: Chromatography is particularly useful for the purification of compounds that are present in minute quantities. This includes substances like pigments, drugs, and other organic compounds.

4. **Identifying the Correct Option**: Given the context of the question, we need to identify which option correctly states what chromatography is used for. The correct answer is that chromatography is used for the purification of compounds available in minute quantities.

5. **Conclusion**: Therefore, the correct answer to the question is that chromatography is used for the purification of compounds that are present in very small amounts.

**Final Answer**: Chromatography is used for the purification of compounds available in minute quantities.
