16. Turn off the instrument.

17. Plug in the DRA using the connector at the back of the sample compartment.

18. Fully open the iris and replace the accessory cover.

19. Turn on the instrument and allow it to initialize.

Powder cell

In some cases, a reflectance measurement may deliver better diffuse reflectance spectra

when the sample is ground to powder form. As shown in Figure 38 and 39, the powder

cell is designed to fit inside the reflectance sample holder in the same manner as the

reflectance standard. Each sample holder comes as a set: one cell with a Spectralon insert

for use as a reflectance standard, and an empty cell for loading the powdered sample. The

quartz window for each cell is compatible with each DRA accessory across the entire

250-2500 nm wavelength range.
