This study describes the application of simultaneous absorbance and fluorescence excitation-emission matrix (EEM) analysis for the purpose of identification and classification of freshwater planktonic algal species.
Analysis of Chlorine, Bromine and Iodine in Water using ICP-AES
The analysis of Br, Cl, and I is possible with ICP-AES at low limits of detection due to an adaptation of the instrument. This adaptation doesn't affect the determination of other elements and will generally improve analytical performance for any elemental lines below 200 nm for example, Pb at 168 nm.
The analysis of brines can be easily performed using the Ultima Expert. Low detection limits are obtained due to the ability of the system to perform the analysis without any dilution thanks to the 3 mm i.d. injector associated with radial viewing and the Total Plasma view that minimize matrix effects and enhance sensitivity. The sheath gas device allows perfect short and long-term stability of the system for routine analysis, without any internal standard, recalibration, or drift correction procedure. Good long term stability allows the use of the best plasma parameters and integration times for enhanced performance.
