ICP-AES

Perkin-Elmer Optima 5300 dual view ICP-AES

Uses
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.

 

Location: Room 1.27 |  Member of Staff: Mr Paul Lythgoe or Mr Alastair Bewsher

Handbook:  ICP-AES-Icpbook  

Sample Preparation

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).

Training & Booking

Training Required
For sample preparation 1 day; Please note that, due to the requirements of clean room protocols, access to the Clean Room for ICP-AES & ICP-MS will be limited to authorised personnel only.

Booking System
Please contact  Mr Lythgoe.  Availability depends on demand, but booking at least a week in advance is advised.
