Foss-NIRSystems Model

The spinning solution composition was measured off-line using a Foss NIRSystems Model 6500 VIS-NIR analyzer (wavelength range 400-2500 nm), equipped with a... 

Spectra recorded on Foss/NIRSystems Model 6500 instrument. Bands were identified using second derivative 2 4 4 1 L = strong band, M = moderate intensity band S = small band All of the bonds below 1100 nm are small. 

Liquid samples can also be scanned directly in scintillation vials. Some instruments offer special attachments for this type of presentation, such as the Rapid Content Analyzer attachment for the Foss/NIRSystems Models 6500 and 5000. 

An example of the effects of these transformations is shown in Table 23.6. Note that all of the data have been retransformed to tristimulus values before calculation of the SEP values. All of the quoted NIR data have been obtained from a Foss-NIRSystems Model 6500. 

Diffuse reflectance measurements were made using a Foss NIRSystems Model 6500 spectrophotometer scanning from 400 to 2500 nm with a 2 nm resolution. The SmartProbe attachment was linked via a 1.5-m fiber-optic cable and mounted a fixed 1 mm above the surface. Using this configuration, light was normally directed onto the surface of the lane where it penetrated the sample... 

The same instrumentation used in the counterfeit currency study was used here (Figure 38.10). The remote reflectance probe of the FOSS/NIRSystems Model 6500 was turned upside down so samples could be placed on its 2" x 2" window, always covered with a black cloth during scanning.
