Reading the units in a residual-solvent report

Residual-solvent results need an analyte name, units and a reporting basis. A number stripped of those labels cannot be interpreted consistently.

For research use only. Not for human or veterinary use.

Keep qualifiers such as below a reporting limit attached to the result. A test for named solvents does not establish the absence of all solvents. An archive should list what the report examined and leave untested substances outside its claims.

Reading checklist

Retain analyte names
Preserve qualifiers and units
Avoid broadening the analyte list
