What is the Minimum quantity required to detect opium in it?

The minimum quantity required to detect opium can vary depending on the method of analysis used. For example, gas chromatography-mass spectrometry (GC-MS) can detect opium at levels as low as a few nanograms per milliliter in biological samples. In environmental samples, such as soil or water, detection limits may range from micrograms to milligrams depending on the extraction and analysis techniques employed. Overall, sensitivity and detection limits can differ significantly based on the specific testing method applied.
