hiiiiiiiiiiiiiiiiiiiiiiiiiii

Answer 2

(B) Refractive Index Detector is a detector used in HPLC.

• HPLC Refractive Index is an index which is used with high-pressure liquid chromatographs. These are used when detecting substances which have limited or no UV absorption.
• The chemical components which are included in this are alcohols, sugars, fatty acids, polymers and carbohydrates.
• Refractive Index detectors are also used in polymer analysis. Refractive Index detectors are considered universal detectors.
• However, they lack in sensitivity and that is a minus point. They are also dependent on temperature and thus, they are not suitable for gradient elution.
• HPLC RI detectors can be a simple and effective way to detect analytes that do not absorb UV light.
