1. The determination requires only six minutes and features a 15-picogram detection limit . 2. Detection limits seem to be around 0.01 % to 0.03 % of volume.3. Other approaches for defining the detection limit have also been developed. 4. There are a number of different " detection limits " that are commonly used. 5. MRSA and " S . aureus " counts fell below detection limits within 180 minutes. 6. For low detection limits , interfering species and high precision, the counting time can increase substantially. 7. All measured values have been below the detection limit . 8. But other kits with detection limits similar to the older Merck kit continue to be used. 9. In principle, detection limits could be well below parts per trillion ( ng / mL ). 10. The highest-numbered transition metal to be observed in concentrations above the detection limit was hafnium ( ).
