Hi,

I am currently trying to develop a standardized method for sample scanning to reduce the variance of the spectra readings within a sample (i.e. I scan the material 10 times, I want the 10 resulting spectra to have less variance).

 

My goal is to measure the dry matter composition of plant material. The material is fairly heterogeneous. Do you have a recommendation to standardize the scanning process? Could a glass or glass like material be used to put pressure on the sample to reduce the variance? What type of glass would be ok (and easy to find?).

 

Any other ideas to reduce the variance caused by particle size of the heterogenous material?
Thank you,

Laurie
