Cleaning 
To clean the Diffuse Reflectance accessory sample holder in 
preparation for analysis: 
1  Remove the sample holder from the accessory and dispose of the 
KBr/sample mixture accordingly.  
2  Remove all residual dust with a swab or appropriate device.  
CAUTION 
Do not scratch the diffuse gold reflectance mirror. 
 
CAUTION 
Do not contaminate the gold mirror with water, as it will hold moisture and be 
evident in your spectral response. 
 
CAUTION 
Do not break the spectrometer seal and attempt to clean interior surfaces. 
Breaking the seal will void the warranty.
