Notes

Results will be reported from the elemental analysis for the element only; the stated identity of the actual sample contents is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. An elemental result provided may be converted to the desired compound by multiplying the result by the appropriate stoichiometric factor.

A 91B report specific to the compound (including the stoichiometric conversion) may by be provided upon request by contacting the laboratory. The stoichiometric factor for stibine from antimony is 1.025.
