Measuring solid materials with a UV/Vis/NIR instrument requires both knowledge of one’s sample and the instrumental techniques available. Most analysts can get overwhelmed by the number and specificity of accessories offered by instruments for UV/Vis/NIR instruments. The dual sample compartment design of the Lambdas 650, 750, 850, 950 and 1050 has resulted in the development of numerous accessories that fit a variety of specific solid material measurement needs.

Questions abound such as:
How do I measure diffuse, specular, or total reflection?
Will I need a relative or absolute reflectance accessory?
Automated vs. manual variable angle reflection measurements, what are the trade-offs?
InGaAs or PbS detector for the NIR, just how much improvement do I get?

These are just a few of the important question users need to know the answers to before measuring a solid sample. This presentation will center on the facts and techniques that analysts need to know so that the correct accessory selection and measurements can be made.
