The Rapid Analysis Probe is specifically designed for speedy spectral collection of powders and other fine-grained materials such as small uniform seeds and grains. Its beveled tip and metal jacket greatly speed up the spectral collection process of fine grained materials to optimize workflow. Simply insert the Rapid Analysis Probe into your fine-grained media, collect the spectrum, use a chemical wipe to swipe the probe clean and move on to the next sample. It’s that easy! The Rapid Analysis Probe comes with a gimbaled white reference for high performance calibration. It can be used for quantitative predictive models.
If using this probe with a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is necessary. The Fiber Optic Illuminator provides the light source needed for sample collection.
