chemical purity

Other unique motive, such as optical reflection, chemical purity etc.

One of the most important features of bacterial cellulose is its chemical purity.

Despite the lack of windows the air was fresh and sweet, a special engineer being responsible for its circulation and chemical purity.

To these concrete five might be added a vaguer sixth, having to do with maintaining a chemical purity in the reaction between product and appraiser.

Industrial ethanol is ethanol standardized for its specifications: chemical purity or technical properties.

Chemical purity helps a clear substance be clearer, but it cannot help an inherently absorbing substance like graphite become clear.

For industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity.

Overall, magnetosome crystals have high chemical purity, narrow size ranges, species-specific crystal morphologies and exhibit specific arrangements within the cell.

Bolivian regulations have further tightened in recent years and singani is held to significantly stricter standards of chemical purity than what may be allowed in other countries.

Stewart's Nature critique focused not on an analysis of Ungar's behavioural claims, but on the chemical purity and composition of the presumed scotophobin.

The level of chemical purity needed is extremely high because the presence of impurities even in very small proportions can have large effects on the properties of the material.

There are, most numerous of all, women who wink discreetly at husbandly departures, overt or in mere intent, from the oath of chemical purity taken at the altar.

A rare characteristic of the stone is its perfect chemical purity: it is ranked as a type IIa diamond, a category which includes less than 1% of all diamonds.

What these virtuous bel dames actually desire in their hearts is not that the male be reduced to chemical purity, but that the franchise of dalliance be extended to themselves.

For example: heroin is almost immediately metabolised into another substance and further to morphine, making detailed investigation into factors such as injection marks and chemical purity necessary to confirm diagnosis.

Because of the required level of chemical purity and the perfection of the crystal structure which are needed to make semiconductor devices, special methods have been developed to produce the initial semiconductor material.

The BSC's certification label on a bottle of dye indicates that the contents are from a batch that passed the tests for chemical purity and for efficacy as a biological stain.

In 1912, Professor L. Erskine Hill of London Hospital stated, "Experimental evidence is strongly in favour of my argument that the chemical purity of the air is of no importance."

This label can be considered ambiguous in so-far as it could be interpreted as meaning that the chemical purity of the compounds is inadequate, when, in fact, this is not the point that is being labored.

This reaction type is of interest to green chemistry because it greatly reduces the usage of organic solvents, reaction product isolation is relatively easy, and it increases the yields and chemical purity with little extra expenditure, if not less.
