Spectra Basic software contains four analysis functions

Absorbance analysis mode:
A sample of synthetic acetyl salicylic acid dissolved in ethanol was analyzed using Absorbance Analysis Mode. The absorption spectrum of the sample shows that the sample has strong absorption spectra at 237 nm and 313 nm.

Concentration analysis mode: concentration and absorbance (Beer-Lambert law)
Determine the concentration of purified protein using the Beer-Lambert law in "Concentration Analysis Mode". After selecting the target wavelength in the Absorbance Analysis Mode screen, five protein standards (BSA) of 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 Analysis Mode: Time and Absorbance (Dynamic Analysis)
Use Time Analysis Mode to measure the fading of phenolphthalein in NaOH over time. For samples with different concentrations of NaOH, the absorbance at wavelengths relevant to phenolphthalein was measured over time.

Light Analysis Mode: Wavelength and Light Intensity
An additional quartz fiber optic kit is used to analyze the intensity of various spectral sources in the UV-visible spectrum. The spectrum of helium is shown below using "Light Analysis Mode"
