Class: XRFDataGenerationActivity

X-ray Fluorescence (XRF) elemental analysis activity.

__

XRF measures elemental composition by detecting characteristic X-ray emissions

from a sample bombarded with high-energy X-rays. Typical output: concentrations

of 10-30 elements per sample (Ni, Pb, As, Cr, Fe, Ca, K, etc.).

__

Data product: XRFElementalProduct (one row per element per sample)

__

Workflow pattern: Direct instrument output (no computational processing step)

_ processedSample -> XRFDataGenerationActivity -> XRFElementalProduct (workflow_id = NULL)_

__

Protocol information: Stored externally; link via protocol_url attribute.

Example protocol parameters (stored in external SOP or DataProcessingActivity

if computational correction is needed):

_ - Beam voltage (kV), beam current (mA)_

_ - Measurement duration (seconds)_

_ - Matrix correction method (fundamental parameters, empirical)_

_ - Calibration date_

_ - Operator ID_

__

Required enum additions to enums.yaml:

_ routemethod:_

_ xrf_analysis: # Add to routemethod permissible_values_
