Substance in chemical analysis

Usage examples of reagent.

Perhaps she had the HI genes and there had been a mistake in the original specimen, a mix-up perhaps, or bad reagents, misapplication of current to the electrophoresis column: any sort of thing like that.

This reagent not only diminishes the excitability, but causes a very great prolongation of the period of recovery.

Dong touched a button, and the splicer spat out a cassette containing the material he had been working on and the reagents he had been using.

The heterogeneousness of the pulp of the papers, and the kind of size with which they are impregnated, lead to differences in the results which are observed with the same chemical reagents.

The requirements in this direction of some inks, however, though of rare occurrence, are to be met by the employment of other and particular reagents.

The three inks were happily mixtures containing different constituents, and so by utilizing the reagent of one which did not affect the other, gradually the encrusted upper inks were removed and later the original writing appeared sufficiently plain not only to be read but to identify it.

Oxidation is performed with greater convenience by wet methods, using reagents, such as nitric acid, which contain a large proportion of oxygen loosely held.

It was a pleasant little room, with three windows--north, west, and south--and bookshelves covered with books and scientific publications, and a broad writing-table, and, under the north window, a microscope, glass slips, minute instruments, some cultures, and scattered bottles of reagents.

The Vochysiaceae family, for example, accumulates aluminium from the soil, and its wood turns blue if we apply a special reagent.

We researchers, on the other hand, leave ours more casually open, swinging round us as we sprint down the corridor from office to lab, though that tradition is fading a bit now as biologists spend less and less time amongst chemical reagents and living things and more in the computer room watching complex multicoloured displays on the screens of the image analysis gear.

A lot of my own time is taken up with money, an almost obsessive issue for most British-based researchers these days: how to find the funds for the salaries of the post-docs, the grants to the students, the capital costs of new equipment, the consumable budget to buy the isotopes and the reagents.

Its empty reagent magazine was supposed to hold two dozen small vials of nucleotides and enzymes and other biochemicals.

But it was useless without the vials of nucleotides, polymerases, and other biochemical reagents.

You could probably break it down in stages by devising a cycle of reagents in just the right sequence, but that would take a complete processing plant specially designed for the job!

But these reagents, which I shall find, and for that matter, upon which I already have my hands, will not turn the living body to blue or red or black, but they will turn it to transparency.
