Subject: Fortified materials / solutions chem. Fortified materials / solutions:These are materials or solutions which have been fortified with the analyte(s) of interest. The fortification is usually made by spiking. These materials or solutions may already contain the analyte of interest so care is needed lest fortification inadvertently leads to levels outside of the range of applicability of the method. Fortification with a known amount of analyte enables the increase in response to the analyte to be measured and calculated in terms of the amount added (assuming 100% recovery), even though the absolute amounts of analyte present before and after the fortification are not known. Note that most methods of fortification add the analyte in such a way that it will not be as closely bound to the sample matrix as it would be if it was present naturally. Therefore, recovery determinations obtained by fortification can be expected to be over-optimistic. Подскажите, кк лучше перевести данный термин? Можно ли сказать Обогащенные вещества(материалы)/растворы? Или вещества(материалы)/растворы повышенной концентрации? И как тогда перевести термин Fortification? |

fortify - увеличивать концентрацию р-ра (есть в хим. словарях) По тексту, чтобы это проделать, возможны 2-вар: а)добавить в аналит спирт или б)воздействовать на в-во механически. И оба варианта называются - spike analyte of interest?! - предмет изобретения? |
