Solution Analytical Facilities

ICENS operates a Perkin Elmer Model 5100PC Atomic Absorption spectrometer fully equipped for flame (air-acetylene or nitrousoxide - acetylene) and graphite furnace atomization. Background correction in flame measurements is achieved with deuterium and tungsten continuum sources.

The transversely heated, platform based furnace is complemented by Zeeman Effect background correction for exceptional (sub ppb) detection limits.

.Autosamplers are used with both flame (AS-90) and furnace (AS-71) to give reproducible sample introduction.

The instrument is used for the determination of some 19 elements in liquid samples such as natural waters, body fluids (blood and urine) and soil extracts.

Ion Chromatography

ICENS operates a Dionex 4500i Ion Chromotography unit equipped with an automatic sampler, gradient pump module, and both conductivity and UV/VIS detectors.

Flow Injection Analyzer

ICENS operates a LaChat Quikchem 8000 two channel ion analyser, equiped with a random access autosampler.

 Nitrate/Nitrite, Phosphate, Silicate and ammonia are determined using colorimetric methods. Two ions can be determined simultaneously. Detection limits are in the sub-micromolar region and and sampler throughput is approzimately 60 samples per hour.

 This technique can be used for analysis of brackish samples. For information on analytical service with this equipment click here.
