Mounting Surface Description**
* On NG-6 FCS, the beam center can be varied by up to 50mm (1.97"). Similar adjustments can be made on other instruments, but special arraingements are required.

** Describes the device mounting surface, NOT the appropriate sample holder, e.g. CCR sample holders normally have clearance slots that mate with the specified tapped holes.

--> Caution: Some instruments (DCS & HFBS) have unique equipment that have different measurements than the standard equipment. <--
