Safety equipment used includes gloves, goggles, lab coat, and closed-toe shoes.

• Gloves are used to protect hands from chemicals and other hazards.

• Goggles are worn to protect eyes from splashes and fumes.

• Lab coat is worn to protect clothing from spills and splashes.

• Closed-toe shoes are important to protect feet from spills and falling objects.

HPLC columns are used in High Performance Liquid Chromatography to separate and analyze compounds in a sample.

• Types include reversed-phase, normal-phase, ion-exchange, size-exclusion, and affinity columns

• Reversed-phase columns use a non-polar stationary phase and are commonly used for separating hydrophobic compounds

• Normal-phase columns use a polar stationary phase and are used for separating polar compounds

• Ion-exchang...read more

There are three main types of solubility: miscible, immiscible, and partially miscible.

• Miscible: substances that are completely soluble in each other in all proportions (e.g. ethanol and water)

• Immiscible: substances that do not dissolve in each other (e.g. oil and water)

• Partially miscible: substances that are partially soluble in each other (e.g. acetone and water)
