For analysis of phenolic acids the BGE was 25 mM sodium tetraborate
decahydrate (pH 9.
Borate ions generated by dissociation of di-sodium tetraborate
were believed to be the reactive species responsible for crosslinking, whereas the free [Na.
The best results were obtained by using a mixture of sodium tetraborate
and SDS as surfactant (MEKC mode).
Thus, the addition of sodium tetraborate
decahydrate (borax) to the 5% attractant concentrate did not influence the capture of C.
1] sodium tetraborate
in concentrated sulfuric acid were added to a test tube immersed in an ice-water bath.

The reaction was stopped by adding potassium tetraborate
Hanover, PA) as a 300 mL aqueous solution of 9% NuLure (vol:vol) and 3% borax (wt:vol; sodium tetraborate
La determinacion cuantitativa de los oxidos mayores, de elementos traza y de las tierras raras se obtuvo por el metodo de ataque Fus-ICP (Lithium Metaborate / Tetraborate
Fusion ICP) y para el resto por espectrometria de emision con plasma (ICP-MS).
Determination of trace metals in siliceous standard reference materials by electrochemical atomic absorption spectrometry after lithium tetraborate
8 g of the fusing agent, namely, oxalic acid, lithium carbonate, lithium tetraborate
(1:1:1), in a platinum crucible, which was then covered and placed in a muffle furnace at 925degC for 10 min.
The substances, which include trichloroethylene; boric acid; disodium tetraborate
, anhydrous; tctraboron disodium heptaoxide, hydrate; sodium eliminate; potassium chromate; ammonium dichromate; and potassium dichromate, are proposed because of their potentially serious effects on human health.
