As new compounds are found in samples submitted to the laboratory, research is done to identify the substances and we include them in our routine screen. If there is possible contamination outside of our routine screening, Diversified offers complete analytical services to identify the substance and solve the problem. We also confirm other laboratory results using advanced gas chromatography and mass spectrometry techniques.

For routine screening purposes, the limits for reporting specific values range from 0.002 ppm to 2.50 ppm, depending on the pesticide in question and the type of sample analyzed. A comprehensive summary of reporting limits and detectability limits for routine screens are available upon request. In addition, special methodologies can be employed to lower the limits for quantitative reporting to one tenth of the levels shown.
