Important Note: Solvents used within this spectrometer should be compatible with polystyrene (cuvette material) and ABS polymer (spectrometer housing material). Use either a glass cuvette or 12mm test tube for solutions with strong organic solvents like acetone, which will damage the plastic cuvettes and the interior of the spectrometer if spilled.

FLIR ONE works by showing you differences in heat energy, so you can detect and measure tiny changes in heat. This lets you see clearly in total darkness, find invisible energy leaks, know what’s going on outside your house at night and much more.

In this lab, students will extract pigments from spinach leaves and analyze their samples using chromatography and colorimetry.

Light from the LED-boosted tungsten light source passes through the solution and into a slit sending light through a high-quality diffraction grating. Colors separate across a sensor and an image of the slit illuminate over 1000 sensors in the array on the other side of the spectrometer. The CCD array detects the brightness of each color of light so you can further analyze the brightness of each particular wavelength. When used with the optional Fiber Optic Cable, the Wireless Spectrometer can analyze light from emission spectroscopy experiments. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source to collect data.

Opticalspectrometer

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.

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.

Students use the results of a spectrometer and a temperature sensor to control the direction of a reversible chemical reaction.
