- 1000ug/mL SILICON 500mL
SiliconLocation: Group 14, Period 3 Storage & Handling: Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container. Chemical Compatibility: Soluble in HCl, HF, H3PO4, H2SO4, and HNO3 as the Si(OH)x(F)y2-. Avoid neutral to basic media. Unstable at ppm levels with metals that would pull F- away (i.e. - do not mix with Alkaline or Rare Earths, or high levels of transition elements unless they are fluorinated). Stable with most inorganic anions with a tendency to hydrolyze forming silicic acid (silicic acid is soluble up to ~ 100 ppm in water) in all dilute acids except HF. Stability: 2-100 ppb levels - stability unknown - (alone or mixed with all other metals) as the Si(OH)x(F)y2-. 1-10,000 ppm single element solutions as the Si(OH)x(F)y2- chemically stable for years in 2-5% HNO3 / trace HF in a LDPE container. Si Containing Samples (Preparation & Solution): Metal (soluble in 1:1:1 H2O / HF / HNO3); Oxide - SiO2, amorphic (dissolve by heating in 1:1:1 H2O / HF / HNO3); Oxide-quartz (fuse in Pt0 with Na2CO3); Geological Samples (fuse in Pt0 with Na2CO3 followed by HCl solution of the fuseate); Organic Matrices containing silicates and non volatile silicon compounds (dry ash at 450°C in Pt0 and dissolve by gently warming with 1:1:1 H2O / HF / H2SO4 or fuse / ash with Na2CO3 and dissolve fuseate with HCl / H2O); Silicone Oils - dimethyl silicones depolymerize to form volatile monomer units when heated (measure directly in alcoholic KOH / xylene mixture where sample is treated first with the KOH at 60 - 100°C to "unzip" the Si-O-Si polymeric structure or digest with conc. H2SO4 / H2O2 followed by cooling and dissolution of the dehydrated silica with HF). Note that the direct analysis of silicone oils in an organic solvent will result in false high results due to high vapor pressure of volatile monomer units such as hexamethylcyclotrisiloxane. The KOH forms the K2+Si(CH3)2O=NaCl, which is not volatile at room temperature. |
