A propos de cet article
Laboratory fortifying stock (LFS) solutions. Assurance® mixed multi-element standards for AA & ICP.
Standards may be diluted in the same matrix as specified; however, caution must be exercised in the choice of the source for your diluents. Diluting the matrix may cause some standards to precipitate. Also, an impure or unknown diluent turns your standard into an unknown. We recommend using only SPEX CertiPrep Matrix Blanks when diluting your standards.
Used for spiking the laboratory fortified blank and the laboratory fortified sample matrix. Two (2 mL) of the LFS solution must be added to a 100 mL aliquot of the laboratory fortified blank. This blank must be carried through the entire sample preparation procedure and analysis scheme. Note: LFS Solution 1 does not contain Ca, K, Mg, or Na because their concentration will vary from one environmental sample to the other.
