Comprehensive Libraries To Match Analysis To Grades
Concentrations Measured From ppm To Percentages
When nothing can be assumed or left to chance.
X-Ray Florescence is the preferred method of analysis where there must be no risk of degradation to integrity such as through wet chemical analysis (acid) or appearance Optical Emission Spectroscopy (OES) of the material
Critical engineering projects cannot allow room for error, one mistake, one short cut can
jeopardise safety, lives, investment, the environment. This is why Positive Material Identification is specified as part of quality assurance procedures.
X-Ray Florescence will identify the base and metallic alloying elements. Holt Bros’ utilise the latest X-Ray florescence technology to identify traces of elements from Aluminium onwards in atomic mass. Our libraries of alloy compositions match the test results with known alloy specifications to provide a positive match to the material requirement. Because of the lower atomic mass limitations of XRF carbon content of steel alloys is commonly determined by OES.
XRF testing is fast, portable and accurate. Every component within a build that can be touched by the hand held test gun can be verified. Internal components are tested before enclosure in tanks or casings.
Every test carries a unique identifier linking it to the job, the tester, the analyser, the client/customer. The control of the records and documentation is under Holt Bros’ Aerospace standard record keeping and controls AC7004 as well as ISO9001.
The immediate on site analysis and reporting when using XRF means that any corrective action can be undertaken without delay minimising lost time and cost.
When incongruities arise, stocks of raw materials can be immediately checked as part of root cause analysis and to provide certainty for on going work.
Retests can take place as soon as corrective actions have been completed and any client requirements adhered to.
Confirmation of use of specified critical materials. Independent of markings or certification.
Prevention of the inclusion of dangerously inappropriate materials—from whatever cause.
Documentary evidence of checks on the actual build. Demonstrating due care and compliance to third party authorisers and project principles
Peace of mind and the elimination of doubt
