GermaniumLocation: Group 14, Period 4 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: Stable in HCl, HF, H3PO4, H2SO4, and HNO3 as the Ge(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. Stability: 2-100 ppb levels - stability unknown alone or mixed with all other metals as the Ge(OH)x(F)y2-. 1-10,000 ppm single element solutions as the Ge(OH)x(F)y2- chemically stable for years in 2-5% HNO3 / trace HF in a LDPE container. Ge Containing Samples (Preparation & Solution): Metal (soluble in 1:1:1 H2O / HF / HNO3); Oxide - GeO (readily soluble in HCl or NaOH), GeO2 (fuse in Pt0with Na2CO3 followed by HCl solution of the fuseate); Geological Samples( fuse in Pt0 with Na2CO3 followed by HCl solution of the fuseate); Organic Matrices (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). |
