The performance of this method was validated by assessing the Standard Reference Materials (SRMs) from the US National Institute of Standards and Technology (NIST) and China National Institute of Metrology (NIM) as well as by comparing these results with those obtained using inductively coupled plasma mass spectrometry (ICP-MS) after complete sample digestion by microwave method.
For many years, graphite furnace atomic absorption spectrophotometry (GFAAS) has been a reliable technique and the preferred method for this heavy metals analysis of tea leaves.
With an inherent toxicity, a tendency to accumulate in the food chain and a particularly low removal rate through excretion, lead (Pb), cadmium (Cd) and arsenic (As) cause harm to humans even at low concentrations.
Contamination of industrial and municipal water supplies with arsenic (As), selenium (Se), and mercury (Hg) can occur from natural deposits, industrial discharge, runoff from mining, landfill and agricultural operations.
Ingestion of trace elements from food can be linked to nutrition, disease, and physiological development. Whether they are needed for proper nutritional value or contain toxic elements, the presence of major and minor elements in food needs to be verified to help determine health effects for the consumer. Acute or chronic exposure to heavy metals can lead to damaged nervous system function and have detrimental effects on vital organs. Food safety laboratories performing these analyses are often high-throughput and require a detection tool that is efficient and cost effective.
This work demonstrates the ability to measure trace levels of various metals in ultrapure acids and photoresist stripper solutions by graphite furnace atomic absorption.
Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.
Precise and accurate measurements at the regulated levels are an important factor for assuring safe drinking water. U.S. EPA Method 200.91 is the method cited by EPA, Health Canada, and the WHO for the use of graphite furnace atomic absorption spectroscopy (GFAAS). In evaluating a GFAAS system for determination of these elements, it must provide good sensitivity, low noise, limited drift, and accuracy in matrices with high salt content (hard water) that might be found in drinking waters. In this work, the PinAAcle™ 900T, with a unique optical system, is evaluated for the use of EPA Method 200.9 for As, Cd, Pb, Se, and Tl in drinking waters.

With instruments that are the industry standard worldwide, PerkinElmer accessories, consumables, methods and application support meet the most demanding requirements and are the preferred choice in thousands of laboratories globally.
Consumers are exposed to low levels of heavy metals on a daily basis and long term exposure can have negative health impacts. Since the elements themselves are distributed unevenly throughout, for example, cereal grain, with the germ and the outer layers having the highest concentrations, analyzing these grains to detect low analyte levels with accuracy and controlled reproducibility is a challenge.
The atomic absorption analysis technique provides a high performance option with features like a closed-furnace design that is sealed at both ends with easily removable bayonet-mount windows. In addition, independently controlled external and internal gas streams provide maximum flexibility, tube life, and sensitivity.
Systems like the PinAAcle™ 900 AA spectrometer make it faster and easier to get from sample to results by reducing your grain method development time, while PerkinElmer consumables and superior services will keep your lab at peak performance.
This guide provides a basic overview of the most commonly used atomic spectroscopy techniques and provides the information necessary to help you select the one that best suits your specific needs and applications.
This document provides detailed instructions regarding the space, accessories and utilities required to operate PerkinElmer’s PinAAcle family of atomic absorption (AA) spectrometers (500 and 900 series) and other major AA accessories.
