Instrument Description:
An instrument used to measure the relative absorption of electromagnetic radiation of different wavelengths in the near infra-red, visible and ultraviolet wavebands by samples.
PI supplied instrument name: Aglient 8453 UV-visible spectrophotometer
Dataset-specific description
For extraction, filters were immersed in sulfuric acid (80%) for 2 h and their absorbance was then measured spectrophotometrically (Agilent 8453 UV-visible spectrophotometer) at fixed wavelength of 787 nm.
