Analyze Solution: Absorbance vs. Wavelength
A sample of synthesized acetylsalicylic acid dissolved in ethanol was analyzed using the Analyze Solution screen. The sample's absorption spectrum indicates that the sample absorbs strongly at 237 and 313 nm.
Concentration: Absorbance vs. Concentration (Beer's Law)
The concentration of a purified protein was determined using the Beer-Lambert law within the Concentration screen. After selecting a target wavelength in the Analyze Solution screen, five protein standards (BSA) with known concentrations were analyzed. A linear fit was applied to create a standard curve, and the concentration of the unknown protein was determined to be 0.215 mmol/L.
Time: Absorbance vs. Time (Kinetics)
The fading of Phenolphthalein in NaOH was measured over time using the Time screen. The absorbance of the wavelength associated with Phenolphthalein was measured over time for samples with varying concentrations of NaOH. The results for a sample containing 0.3M NaOH and Phenolphthalein are provided below.
Analyze Light: Intensity vs. Wavelength
The Quartz Fiber Optic Cable Set was used to analyze the intensity of various spectral sources across the UV-Visible spectrum. The spectrum for Helium is shown below using the Analyze Light screen.
Applications

Product Guides & Articles
Spectrometers
A spectrometer is a device that allows scientists to dissect light into its constituent colors, akin to separating the vibrant hues of a rainbow. By precisely dispersing the light, spectrometers provide a unique window into the physical and chemical properties of objects.
Spectroscopy
Spectroscopy is the investigation and measurement of spectra produced by matter interacting with or emitting electromagnetic radiation. During a spectroscopy experiment, electromagnetic radiation of a specified wavelength range passes from a source through a sample containing compounds of interest, resulting in absorption or emission.
