Atomic fluorescence spectrometer

Introduction

An atomic fluorescence spectrometer is an analytical instrument used to measure the concentrations of the metals and the metalloids by the atomic fluorescence spectrometry (AFS), and it is used in the environmental, the food, the pharmaceutical, the geological, and the many other applications. The atomic fluorescence spectrometer vaporizes and atomizes the sample, such as by the hydride generation or the cold vapor generation, and the atoms absorb the light from the excitation source and emit the fluorescence, which is measured and related to the concentration; the atomic fluorescence spectrometer consists of a sample introduction and the atomization system, an excitation source, such as the hollow cathode lamp, a fluorescence detection system, and a control and a data analysis system, and it provides the concentrations of the elements, such as the arsenic, the mercury, the selenium, and the antimony, with the high sensitivity; the atomic fluorescence spectrometer is used for the analysis of the trace metals in the water, the foods, the biological samples, and the geological samples, for the environmental monitoring, for the quality control, and for many other applications, and it is an essential instrument for the trace element analysis. Atomic fluorescence spectrometers are used in the environmental laboratories, in the food industry, in the pharmaceutical industry, in the geological, and for many other applications. With their fluorescence detection, atomic fluorescence spectrometers are essential for the trace element analysis.

FAQ

Q1: What testing scenarios is this spectrometer mainly applied to?

A: The atomic fluorescence spectrometer is used in environmental monitoring, food safety testing, clinical laboratories, geological survey, pharmaceutical analysis and research institutions to measure trace and ultra-trace concentrations of elements including arsenic, mercury, selenium, lead, tin, antimony, bismuth and tellurium. It supports drinking water and wastewater heavy metal testing, food safety contaminant analysis, clinical toxicology testing, geological exploration, pharmaceutical impurity analysis and environmental pollution monitoring. The atomic fluorescence technique with hydride generation provides exceptional sensitivity for elements that form volatile hydrides, achieving detection limits far lower than conventional atomic absorption. It is essential for environmental agencies, food testing laboratories, clinical facilities and research institutions requiring ultra-trace element analysis for regulatory compliance, public health protection, geological exploration and scientific research where very low detection limits are required for toxic and essential elements in complex sample matrices.

Q2: What standards does the spectrometer comply with?

A: The instrument supports analytical methods referenced in EPA methods for heavy metals, ISO standards for water and food analysis, GB/T and HJ standards for environmental and food testing, and pharmacopoeial methods for elemental impurities. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified reference standards traceable to international standards.

Q3: What is the warranty period for the whole machine and key components?

A: The whole spectrometer is covered by a 12-month warranty. The atomizer, excitation source, detector, hydride generator and controller are covered, while lamps, tubing, reagents and standards are consumables excluded from warranty. Damage from improper sample introduction or unauthorized repair is excluded. Extended service contracts are available.

Q4: Is this device difficult to operate? Is professional training required?

A: Operation requires trained analysts familiar with atomic spectroscopy, sample preparation and hydride generation chemistry. We provide structured training, operation manuals and application support. Proper sample digestion, reagent preparation, instrument optimization and result interpretation are important for accurate ultra-trace analysis.

Q5: What is the typical lead-time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is regular calibration required? What is the recommended calibration cycle?

A: Calibration with certified standards should be performed before each analytical batch. Hollow cathode or electrodeless discharge lamp replacement follows usage. Full instrument performance verification annually. Hydride generator tubing and fittings inspected and replaced periodically. Daily performance verification with a quality control standard recommended for regulated laboratories.

Q7: Are supporting consumables universal?

A: Lamps, reagents, standards and tubing are available from multiple qualified suppliers, though instrument-specific parts should be verified. Long-term consumable and reagent cost is moderate depending on sample volume and element types.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes element configuration, sample introduction type, autosampler capacity and software features. Additional lamps, kits and accessories can be ordered separately. Custom orders extend delivery lead-time.

Q9: Does the purchase include on-site installation and commissioning service?

A: Yes, atomic fluorescence spectrometers include on-site installation, commissioning, calibration and operator training by certified application specialists. Site preparation guidance is provided before delivery to ensure ventilation, power and gas supply requirements are met.

Q10: What types of samples are compatible with this equipment?

A: The spectrometer analyzes liquid digested samples including water, food, biological, geological and environmental samples within the measurement range. Solid samples require acid digestion before analysis. Mercury analysis requires special cold vapor technique and contamination control. Users should follow proper sample digestion procedures, use high-purity reagents and standards for ultra-trace analysis, maintain hydride generator performance, control contamination from glassware and reagents, and perform regular calibration and quality control to ensure accurate, reliable trace element results at very low detection limits.
