A: Optical density (OD) in a UV spectrophotometer measures the absorbance of ultraviolet light by a sample, indicating the concentration of substances like DNA, proteins, or bacterial cultures. It quantifies how much light is blocked as it passes through the sample. This value is logarithmic and unitless, often reported as absorbance (AU).
A: A spectrophotometer measures optical density by passing UV or visible light through a sample and detecting the transmitted light. The difference between incident and transmitted light correlates with the sample's absorbance. This data is converted into an OD value using the Beer-Lambert law.
A: UV light is used in optical density spectrophotometers because many biological molecules (e.g., nucleic acids, proteins) absorb strongly in the UV range (260-280 nm). This allows precise quantification of these compounds. UV measurements are especially critical for applications like DNA purity assessments.
A: Optical density (OD) and absorbance are often used interchangeably in spectrophotometry, both representing light absorbed by a sample. However, OD may include scattered light effects, while absorbance strictly follows the Beer-Lambert law. In practice, both terms refer to the logarithmic attenuation of light.
A: Calibrate a UV spectrophotometer by zeroing it with a blank solution (e.g., solvent or buffer) to establish a baseline. Verify accuracy using standards with known OD values, such as absorbance calibration filters. Regular maintenance, like lamp replacement and cuvette cleaning, ensures consistent results.
