Application Overview

Engineering positive Material Identification (PMI) for the real process

Alloy/material PMI using suitable calibration and configuration. The useful result is not defined by the instrument name alone: the measurement point, sample or equipment condition, range, response, pressure and temperature, possible interferences, installation, data interfaces, and reference basis determine whether a configuration is appropriate.

Blue Dragon Technology uses the Core relationship map to identify relevant instruments, then qualifies the final configuration against the project. The system boundary may also include sampling or mounting hardware, utilities, signal integration, alarms, verification, FAT/SAT, commissioning, training, spares, and controlled documentation.

Measurement Objective

What the application needs to establish

Alloy/material PMI using suitable calibration and configuration. Define the required range, units, response, accuracy or uncertainty, alarm/use case, and comparison or reference basis before configuration.

Operational Value

Why the measurement matters

Material identification

Identify elemental composition to support material selection, segregation, or verification.

Quality control

Screen incoming materials, products, ores, alloys, or process samples against defined criteria.

Field decisions

Provide rapid screening where laboratory turnaround would delay the next action.

Traceable workflows

Use suitable calibrations, reference materials, sample preparation, and confirmation methods for the required decision.

Measurement Technology

How the measurement is approached

PMI uses XRF elemental screening with an application library and calibration suited to the alloys or materials being verified. Surface condition, coatings, geometry, element limitations, reference samples, alloy library, acceptance rules, and confirmation methods determine the reliability of the field decision.

Installation Context

Typical operating locations

Fabrication shops and incoming material inspection
Refinery and chemical-plant maintenance
Piping, valves, vessels, and alloy components
Warehouse/material control
Shutdown and mechanical-integrity programs

Selection Guidance

Instrument-selection considerations

Elements of interest and required detection or quantification objective
Material matrix, homogeneity, particle size, thickness, surface condition, and sample geometry
Field screening versus laboratory analysis
Calibration, application mode, reference materials, sample preparation, and confirmation method
Required repeatability, reporting, libraries, traceability, and acceptance criteria
Radiation-safety controls, operator training, accessories, and data management
