How do you measure the diffuse reflectance spectra of any solid sample?

Hello
Thanks for this video.
May I know what is the minimum quantity of the material for analysis?

[@gaureearolkar1522]

is it surface characterization technique or bulk?

Is it possible for black materials to have negative absorbance?

[@perkinelmer]

Negative absorbances are not possible, even for black materials. The lowest possible value would be zero. We should have an app note out shortly about this topic so keep an eye out for that. Hope that helps!
