Muhammad Ismail Popular answer

You can use even a micro gram of sample to measure its UV

Muhammad Ismail

Tuhin Khan

In general yes. But you need to ensure that the sample has not degraded by some other means (e.g., improper storage).

Yuwei Fan

It is a non-destructive analysis if the sample is not reactive under UV light. You can recover the sample for other application and testing.
