Mississippi State University
Notice of Proposed Sole Source Purchase
267-047
Mississippi State University anticipates purchasing the item(s) listed below as a
sole source purchase. Anyone objecting to this purchase shall follow the
procedures outlined below.
1. Commodity or commodities to be purchased (make, model, description):
X-Ray Tube, 2.2kW, Cu, Ceramic,LFF,Canon,and Corrosion Inhibitor(BTA),10mL
This is a direct replacement X-ray Tube for the Rigaku SmartLab X-ray Diffractometer (XRD)
currently located at the Mississippi State University Institute for Imaging and Analytical
Technologies.
2. Explanation of the need to be fulfilled by this item(s), how is it unique from all other
options, and why it is the only one that can meet the specific needs of the department:
The requested 2.2 kW Cu Ceramic LFF X-ray tube is a specialized replacement component for
the existing Rigaku SmartLab X-ray Diffractometer. The replacement tube must meet Rigaku's
specifications to ensure compatibility, performance, and safe operation.
Rigaku Americas Corporation has confirmed that its equipment incorporates proprietary
designs and requires Rigaku factory components for replacement parts. The specified X-ray
tube is manufacturer specific. Therefore, non-Rigaku alternatives are incompatible with the
existing system and will adversely affect its performance or safety.
Accordingly, a Rigaku factory replacement tube is required to restore and maintain the proper
operation of the existing SmartLab XRD.
3. Name of company/individual selling the item and why that source is the only possible
source that can provide the required item(s):
Rigaku Americas Corporation is the original manufacturer of the SmartLab 3KW XG X-ray
diffractometer and the authorized source for replacement components specified for the

system. Rigaku has confirmed in writing that its equipment incorporates proprietary designs
and that replacement parts must meet Rigaku factory-quality requirements. Rigaku also
confirmed that it has no partnerships or agreements with other service providers within the
United States and does not certify or endorse non-Rigaku personnel or representatives to
maintain or service its equipment. Accordingly, the required 2.2 kW Cu Ceramic LFF X-ray tube
must be procured through Rigaku Americas Corporation to ensure compliance with the
manufacturer's specifications and requirements.
4. Estimated cost of item(s) and an explanation why the amount to be expended is
considered reasonable:
Estimated cost: $9,872.70
The requested component is a specialized replacement X-ray tube specified for the existing
Rigaku SmartLab XRD system. It is not a generic commercial component that can be
competitively substituted without potentially affecting compatibility, performance, and safety.
Rigaku has confirmed that replacement parts for the system must meet Rigaku factory-quality
requirements.
The expenditure is necessary to restore the existing XRD system to operational condition and
maintain the department's analytical capabilities. The estimated cost of $9,872.70 is considered
reasonable given the specialized nature of the component, its manufacturer-specific
requirements, and the need to ensure compatibility and safe operation with the existing
system.
5. Explanation of the efforts taken by the department to determine this is the only source
and the efforts used to obtain the best possible price:
The department investigated alternative sources for the specified X-ray tube. The department
contacted Canon Medical Components USA regarding the 2.2 kW, Cu, Ceramic, LFF X-ray tube.
On August 18, 2026, Canon confirmed that it could not supply the customized tube and
directed the department to the system manufacturer, Rigaku Americas Corporation.
The department subsequently obtained pricing directly from Rigaku Americas Corporation.
Given the specialized, manufacturer-specific requirements of the component and the need to
restore the existing SmartLab XRD system, the department requested the best available pricing
from the manufacturer. Rigaku provided pricing of $9,872.70 for the required replacement
tube.
