ICP-OES
An overview of ICP-OES
ICP-OES is a fast multi-element solution technique with a dynamic linear range and moderate-low detection limits (~0.2-100 ppb). The instrument (Perkin Elmer Optima 5300DV) uses an ICP source to dissociate the sample into its constituent atoms or ions, exciting them to a level where they emit light of a characteristic wavelength. Up to 60 elements can be screened per single sample run and the samples can be analysed in a variety of aqueous or organic matrices. There are fewer chemical interferences than with FAAS, but some spectral interferences are possible and there are some element limitations. Sample volumes are typically 2-4mls depending upon number of wavelengths required and the total dissolved solids must be <5 %.Access and Charges
Potential users for ICP-OES should in the first instance contact Dr Lorna Eades for training on the use of the instrument. The instrument is located in room 111a, School of Chemistry (Joseph Black Building, Kings Buildings). An online booking system is in operation for experienced users, this can be accessed from the link below. New or inexperienced users must arrange time directly with Dr Lorna Eades who is available Mon, Tue, Fri 0930-1300 and Thurs 0930-1800.
Click for on-line booking.Users will be charged on the basis of their time spent on the instrument and must provide an IT form, Purchase Order Number or Cost Center prior to using the instrument.
