The performance of a low consumption thermospray nebulizer for specific use in micro-HPLC and general use in FT with ICP-AES detection

Elemental matrix effects in ICP-AES

“…When using a desolvation system, the signal reduction induced by potassium increased with the temperature of the spray chamber. 196 Besides the aerosol heating and condensation temperatures, some other variables must be considered in order to minimize the matrix effects when using a desolvation system. Thus, using an ultrasonic nebulizer coupled to a desolvation system, Masson et al 165 found that the lower the liquid flow rate the stronger the matrix effect observed in an axial ICP-AES.…”

Effects of Matrix Elements on the Analyte Emission Signals in Inductively Coupled Plasma Optical Emission Spectrometry Using a Thermospray Sample Introduction System

“…To maintain a stable plasma, the increased solvent plasma loading can be effectively reduced using different desolvation devices. 10,20 However, the problem of matrix effects is still the limiting factor for the determination of trace elements in complex m atrices. 1,9 -11,14 De Loos-Vollebregt et al 11 observed signal enhancement for atom and ion lines of Cd, Mg, and M g in the presence of Na, K, and Ca, whereas in the presence of HCl, HClO 4 , and H 3 PO 4 the same authors reported signal depressions.…”

Trends and Developments

“…The column effluent was connected directly to the spray chamber of the detector. Other workers have developed a thermospray nebuliser as an interface for coupling micro-HPLC with an ICPAES detector (Elgersma et al, 1991). A thermospray nebuliser was used as an interface for coupling HPLC with ICPAES (Laborda et al, 1991).…”
