Samples go to a UKAS accredited laboratory with full chain of custody, and we interpret the results into practical actions for you.
What the reported symptom tells us
sample results needed after a risk assessment or an incident. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.
