| 摘要 |
A prefabricated micro-quantity reagent dosage unit for an analytical procedure, is provided involving reaction of a chemical reagent with a reaction mixture to be analyzed. The unit comprises a composite structure which incorporates the chemical reagent and includes carrier means for carrying the chemical reagent and magnetizable material to facilitate handling of the carrier means and for effecting movement of the latter, under action of a magnetic field acting on the magnetizable material, when the carrier means is subjected to the reaction mixture. The carrier means is provided with precise micro-quantities of reagent preparatory to a single analysis and by virtue of the magnetizable material the composite structure may readily be handled for storage under conditions favorable for the durability of the reagent, simultaneously enabling transfer of the composite structure to the reaction mixture without risk of contamination of the latter. |
