Whether you require a single dedicated element or a multi-element. The developed method also provides low usage of sample solution in contrast to conventional nebulizer in the FAAS system.Ĭoncentric nebulizer Flame atomic absorption spectrophotometry High performance liquid chromatography T-shaped slotted quartz tube Vitamin B12.Ĭopyright © 2022. For maximum flexibility from your Thermo Scientific iCE 3000 Series Atomic Absorption spectrometer, a huge range of pre-coded and un-coded Thermo Scientific Hollow Cathode Lamps are available, to handle your chosen elements for analysis. The hollow cathode contains some of the analyte know to be in the sample. Two different vitamin tablets were analyzed by the optimized hyphenated system. The lamp is filled with 1-5 Torr of an inert gas. A successful separation and detection of the analyte was achieved within 3.0 min that offers high sample throughput. Recovery studies were also conducted to verify the accuracy and applicability of the developed method for vitamin tablets and excellent percent recovery results (~ 100%) with low standard deviation values were obtained when matrix-matching calibration strategy was performed for each vitamin tablet. Hollow cathode lamps emit light that is specific to the element, and this light is directed through the flame to allow for measurement during atomization. Limit of detection (LOD) and limit of quantitation (LOQ) for the HPLC-NI-T-SQT-FAAS system were calculated to be 1.6 and 5.3 mg/kg as Co, respectively. After optimizing some parameters such as mobile phase flow rate and pH, nebulizer gas flow rate, T-SQT height and injection volume, linear range for the analyte was determined between 4.7 and 92 mg/kg as Co. Vitamin B12 was selected as an analyte to show the applicability of the new hyphenated system. The Hollow cathode Lamp is made with an element (metal) as the cathode encased in a bulb with a low pressure inert gas. T-SQT was also used to intensify the interaction of atoms with the hollow cathode lamp light. A glass concentric nebulizer was linked to T-shaped slotted quartz tube (T-SQT) using a tubing to transfer the liquid solution eluted from the chromatographic system into the atomization region of FAAS system. For maximum flexibility from your Thermo Scientific iCE 3000 Series Atomic Absorption spectrometer, a huge range of pre-coded and un-coded Thermo Scientific Hollow Cathode Lamps are available, to handle your chosen elements for analysis. The deuterium lamp and its cover become very hot during operation. A novel nebulizer interface (NI) was proposed to combine high performance liquid chromatography (HPLC) and flame atomic absorption spectrophotometer (FAAS).
