A useful laboratory inquiry begins with a specific question. The same powder can raise several different questions: its chromatographic profile, the amount of a named analyte, or the evidence supporting an identity. Describing the question first helps establish whether a suitable scope is available.
Identify the material
Include the material name, batch or lot identifier, approximate quantity and any known formulation. State whether the information comes from a label, supplier specification or an earlier report. Keep the original source identifiable.
Describe the result you need
Explain what decision the measurement is intended to support. Avoid using “purity” as the only description when you need a specific quantitative result. Chromatographic area percentage and analyte mass per vial are different measurements.
Share the relevant documents
- Supplier batch information or certificate, if available.
- Previous analytical records and the method used, if known.
- Known storage and handling history relevant to the sample.
- Any confidentiality or reporting requirements.
Confirm acceptance before shipment
Feasibility, references, handling, preparation and deliverables need to be agreed before material is sent. An inquiry is the start of that discussion; it is not an automatic sample acceptance.
