The discussion centers on the challenges of using a Raman TruScan with a 785 nm laser for material identification due to excessive fluorescence, resulting in poor signal quality. In contrast, another lab successfully obtains consistent signals with the same equipment and sample. Possible reasons for the differing outcomes include variations in sample preparation, instrument calibration, or environmental factors. The conversation also hints at the potential relevance of Arduino sensors for on-the-spot purity detection of street drugs. Overall, the thread highlights the complexities of achieving reliable Raman spectroscopy results.

Two raman instruments of the same model not giving reproducible results
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
