What unit of measurement does a SciAps X-550 XRF analyzer report?
Answer
A SciAps X-550 XRF analyzer usually reports elemental composition as a weight percent (wt%) or parts-per-million (ppm) concentration, depending on the selected mode and calibration, rather than a single universal physical unit.
Before you start: stop right away if…
- XRF instruments can emit ionizing radiation when testing; follow the manufacturer’s safety procedures and never point the analyzer at people.
Follow these steps
Note the selected analysis mode
On the X-550, open the current app or mode name shown before or after a test and write it down.
You should see: You know which mode produced the reading you are interpreting.
Read the unit label on the result screen
After a measurement, look next to each element value for labels such as %, wt%, or ppm.
You should see: The display shows whether results are percent by weight, ppm, or another labeled concentration unit.
Confirm against the mode documentation
Open the SciAps documentation or Profile Builder notes for that exact mode and match the reported unit to the calibration description.
You should see: The unit on screen matches the expected reporting format for that mode.

Extra tips
What to look for: Result labels such as %, wt%, ppm, or element symbols next to numeric readings on the X-550 display
Before you change anything: Confirm the exact app or analysis mode currently selected on the instrument. Do not change calibrations unless you are trained for that mode. Keep the window and sensor clear of debris before comparing readings. Use only the official SciAps manuals or software for mode-specific units.
