What does a protein skimmer do? Protein skimmers actively remove waste products from fish, plants, and invertebrates (along with any dead organisms or uneaten food) before it has a chance to break down and compromise water quality.
Protein absorbs strongly at 280 nm due to a number of its constituent amino acids. The peptide bonds found in the amino acids also absorb at 205 nm. The UV absorbance of protein can be used both to quickly image and acquire spectra of microscopic samples non-destructively. The spectra can also be used to determine protein concentrations and the relative amounts of protein to DNA or RNA.
