In order to detect analytes which are minor components of a complex gas mixture the sensitive layers should be highly selective to these analytes.
Pervaporation (PV) is a separation process in which minor components of a liquid mixture are preferentially transported by partial vaporization through a non-porous permselective (selectively permeable) membrane.
Decreasing the limit of detection of the forensic process to one copy of DNA is a powerful mechanism by which to increase the information content on minor components of a mixture, which is particularly important for probabilistic system inference.
For some peptides in dilute and simple mixtures, the relative ion flux depends significantly on handling and surface exposure, but when the target and calibrant are minor components of a complex mixture of endogenous MHC I peptides, a constant relative flux is more likely to be observed.
Because drug-resistant HIV-1 variants often exist as minor components of an otherwise drug-susceptible HIV-1 patient infection, PCR amplicons from these constructs were paired and mixed in different proportions (a "solute" template was diluted by a "solvent" template) for analysis by multiplex OLA.
"But when you consider how many MRSA infections are occurring in North America at the moment, if they're a minor component of a major disease, that's still something we need to be aware of".
One example of wax crystals determined by a minor component of a complex mixture is the transversely ridged rodlets, shown in Fig. 7g, which contain high amounts of hentriacontane-16-one (palmitone) [48].
In contrast, trainings for response professionals might only discuss household preparedness as a minor component of a program largely focused on occupational responsibilities for whole community preparedness and response.
Since that first incredible discovery in 1974, archaeologists have unearthed approximately 2,000 full-sized terracotta warriors and horses from three ancient pits, yet the terracotta site is in fact only a minor component of a much grander tomb construction under which lie thousands of treasures waiting to be excavated.
Unfortunately, this strategy cannot be used when the target is difficult to produce in sufficient quantities for FP, is a minor component of a complex mixture, or is an integral membrane protein.
In one recent study, these factors not involving cattle movements were found to be a minor component of a full contact network, whereas unrecorded movements on and off shared grazing were more important (M.C. Vernon, unpublished).
