UV-Vis-NIR Powder Cell Kit
Powder cell kits are used for diffuse reflectance spectroscopy (DRS). The powders cell is used to hold powder samples, or pastes, against the reflectance port of the internal or external DRA. The kit contains a prepacked PTFE cell, for use as a reflectance standard, and an empty powder cell holder for sample measurements. Each cell has a quartz window and for measurements across the 250–2500 nm wavelength range.
The powder cell holders accommodate a range of sample volumes. The large powder cell for the external DRA holds powder volumes from approximately 2 to 20 mL, while the small powder cell for the internal DRA can hold volumes from 0.2 to 2 mL dependent on the particle size and opacity.
