It was, his critics said at the time, like judging a wine by chemical assays.
4.
Many CSF leaks do not show up on imaging and chemical assays, thus such diagnostic tools are not definitive to rule out CSF leaks.
5.
Due to scientific chemical assay techniques, analysis has now shown that the fruit, roots and herbs of this particular Equatorial sub-area offer some of the strongest anti-oxidant protection in the world.
6.
To verify the completion of the fermentation they can be quantified by chemical assay ( glucose and fructose are " reducing " sugars that react with an alkaline copper solution called Fehling's solution ), an enzymatic method, or by infrared spectroscopy.
7.
Although in general Monotype cast type characters can be visually identified as having a square nick ( as opposed to the round nicks used on foundry type ), there is no easy way to identify the alloy aside from an expensive chemical assay in a laboratory.

:From our article, Analytical chemistry " is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials . " Specific chemical assay techniques exist for a variety of types of chemical; you may need a biochemistry lab, inorganic chemistry lab, and so on, depending on what substance you're trying to positively-or negatively detect.
9.
For example, IMC has been widely used for many years in shelf life studies of solid drug formulations in the pharmaceutical industry ( Pikal et al . 1989, Hansen et al . 1990, Konigbauer et al . 1992 . ) IMC has the ability to detect slow degradation during simulated shelf storage far sooner than conventional analytical methods and without the need to employ chemical assay techniques.
