A considerable improvement in the detection limit of a liquid-membrane ion-selective electrode has been achieved by using a metal-ion buffer as internal solution.
22.
Low detection limits and high selectivity require engineering the CNT surface and field effects, capacitance, Raman spectral shifts and photoluminescence for sensor design.
23.
The minimum detection limits of the kit most widely used in the surveys is advertised as 100 parts per billion ( ppb ).
24.
There are multiple possible configurations and a low-albedo super-Earth at that distance would have an apparent magnitude below the current all-sky-survey detection limits.
25.
Even with pipeline leak volumes within SCADA detection limits, sometimes pipeline leaks are misinterpreted by pipeline operators to be pump malfunctions, or other problems.
26.
The additional sample flow generated by the VPM adds two orders of magnitude to the lower detection limit of the qNano and qViro instruments.
27.
By introducing several MeCAT labels to a biomolecule and further optimization of LC-ICP-MS detection limits in the zeptomol range are within the realm of possibility.
28.
Carbon nanotubes are useful sensing materials because they have low detection limits, and quick response times; however, bare carbon nanotube sensors are not very selective.
29.
Although the mass range was limited to slightly over 120 u, fragmentation of some of the heavier molecules negated the need for a higher detection limit.
30.
Detection limits are typically in the parts per billion range if there is limited sample or parts per trillion if there is an unlimited sample size.
