Step 1: Understand what HPLC stands for. HPLC means High-Performance Liquid Chromatography.
Step 2: Know that HPLC is a technique used to separate and analyze different components in a mixture.
Step 3: Learn that detectors are important in HPLC because they help identify and measure the components after separation.
Step 4: Recognize that there are different types of detectors used in HPLC, such as UV-Vis spectrophotometers, fluorescence detectors, and refractive index detectors.
Step 5: Identify that among these, UV-Vis spectrophotometers are the most commonly used type of detector in HPLC.
