Visible Range Spectrophotometer Comparison Graphs

Five identical tests were run to illustrate the quality of data you can expect from each device. The graphs below are intended to help you decide which spectrometer best fits your needs. They provide performance comparisons of Vernier Go Direct SpectroVis Plus and Vernier Spectrometer.

Why don’t all of my spectrometers and/or Colorimeters read the same absorbance value for the same sample?

Comparing Hydrogen Emissions

The emission line graphs for hydrogen gas have been prepared by overlaying two data collection runs. One run was set to capture the 656 nm peak without saturation, and other was set at a longer sample time in order to capture the emission lines near 434 nm and 410 nm.
