Perkin-Elmer Optima 5300 dual view ICP-AES
Analysis of a wide range of elements (list available) in solution, sequentially. Detection limits vary from element to element and depend upon method, nature of sample and standards used, but 10-100 ppb is potentially achievable for a wide range of elements. Analysis of 24 water samples + 12 standards for Na, K, Ca, Mg, Si, S, P, Fe and Mn might typically take 1/2 day of instrument time.
Liquid samples should normally be aqueous, acidified (typically 2% HNO3 or equivalent), filtered (removing particles > 0.45 um) and with a total dissolved solids content of less than 10,000 ppm. Samples not conforming with these requirements may require pretreatment. Non-compliance with these requirements must be drawn to the attention of AGU staff, not least of all to prevent damage to equipment.
Solid samples dissolved by mixed acid digestion, often involving HF. This procedure must be done in the Chemical Laboratory (Room 1.18) in consultation with Mrs Davies. Special training is required (see Dr Polya or Mrs Davies to make arrangements).
