Iron 1000ul/mL

Iron

Location:  Group 8, Period 4
Atomic Weight:  55.847
Coordination Number:  6
Chemical Form in Solution:  Fe(H₂O)₆³⁺

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, HNO₃, H₂SO₄, HF, H₃PO₄. Avoid basic media. Stable with most metals and inorganic anions in acidic media.

Stability:  2-100 ppb levels stable for months in 1% HNO₃ / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5% HNO₃ / LDPE container.

Fe Containing Samples (Preparation & Solution):  Metal (soluble in HCl); Oxides (if the oxide has been at a high temperature then Na₂CO₃ fusion in Pt⁰ followed by HCl dissolution, otherwise dissolve in dilute HCl); Ores (see Oxides above using only the fusion approach).
