Raman Spectroscopy help

TL;DR

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?

Hope I’m not being presumptious if I make a half-baked attempt at merging our threads:

Arduino sensors for detecting purity of streetdrugs on the spot

You might find something of value in there, in spite of my arrogance.
