1000ug/mL CESIUM 125mL

Cesium Expanded View


Location:  Group 1, Period 6
Atomic Weight:  132.9054
Coordination Number:  (6)
Chemical Form in Solution:  Cs+(aq)
(coordination number in parentheses is assumed, not certain)

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 dilute HCl, HNO3, H2SO4 and HF aqueous matrices. Stable with most metals and inorganic anions. Forms insoluble Cs2[PtCl6].

Stability:  2-100 ppb levels stable for months in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 0.1% HNO3 / LDPE container. Will crystallize out of higher (~ 5%) levels of HNO3 at > 1000 µg/mL.

Cs Containing Samples (Preparation & Solution):  Metal (dissolves very rapidly in water); Ores (sodium carbonate fusion in Pt0 followed by HCl dissolution - blank levels of Cs in sodium carbonate critical); Organic Matrices (Sulphuric / peroxide digestion or nitric / Sulphuric / perchloric acid decomposition).
