Answer
High-performance liquid chromatography (HPLC) is a highly effective separation technique widely used for various compounds, including sugars. It allows for the precise separation and quantification of different sugar types in a mixture. HPLC works by passing the mixture through a column packed with a stationary phase and using a mobile phase to elute the components at different rates based on their interactions with the stationary phase.

Answer
Atomic absorption spectroscopy is primarily used for analyzing metal elements in samples, and is not suitable for separating or analyzing organic compounds like sugars.

Answer
While UV-visible spectrophotometry can be used to determine the concentration of different compounds, it is not an effective method for separating sugars from one another.

Answer
Flame tests are used mainly for identifying the presence of certain metal ions based on the color of the flame produced; they are not applicable for separating organic compounds like sugars.
