“Chloride binding by the proteins was assayed spectroscopically by monitoring the chloride-induced blue-shift of their absorbance spectra.”

“Total phosphorus was determined spectroscopically, using persulfate-oxidized samples, by molybdate blue absorption.”

“The approximate enzyme concentration was determined spectroscopically as previously described.”

“Their photobleaching behavior was studied using spectrally resolved emission spectroscopy.”

“Besides a high degree of oversampling, the available noise power is also spectrally shaped.”

“The galatheid crabs had particularly high reflectances, relatively spectrally neutral on the small carapaces, and quite red on the large legs.”

“A total of 24 females and 137 great calls were of sufficient quality to be spectrographically analysed from the four populations.”

“In that event a speck as small as the head of a pin can be analyzed spectrographically.”

“Enter Pembient, a biotech startup developing products that are genetically and spectrographically similar to rhino horn.”

“The concentration of unbound protein in the supernatant was determined spectrophotometrically at 410 nm.”

“The DNA was then dissolved in distilled water and quantified spectrophotometrically.”
