Instrumental Method - GCSE Chemistry Definition

The term 'instrumental method' in GCSE Chemistry refers to techniques that use special machines to analyse chemical substances. These methods help scientists to identify what chemicals are present in a sample, how much of each chemical there is, and their properties. Unlike simpler methods, instrumental methods are usually faster, more accurate, and can detect even very small amounts of a chemical. Examples include gas chromatography and mass spectroscopy. These methods are often used in laboratories and industries to ensure that products like medicines and food are safe and made to the right standard.
