Overview

The new Advanced Platform design suspends the platform in the tube using three small pins in a triangular layout. This has the advantage of minimizing wall contact and reducing thermal conduction from the tube walls resulting in even and rapid heating almost exclusively from thermal radiation, an ideal platform.

Features and Benefits:

  • Even and rapid heating
  • Improved sensitivity for some applications
  • Improved batch to batch reliability
  • Exclusive and patented design - only from PerkinElmer!

The tubes are compatible with PerkinElmer PinAAcle 900T, PinAAcle 900Z, AAnalyst 600, AAnalyst 800, Model 4100ZL, Model 4110ZL, Model 5100ZL, SIMAA 6000 Zeeman AA instruments.

Application Note

Fast Digestion Analysis of Lead and Cadmium in Rice Using GFAAS with Deuterium Background Correction

Toxic elements, such as lead (Pb) and cadmium (Cd), are entering the food chain through environmental contamination. Rice, as the most widely consumed cereal grain in Asia, can quickly pick up Pb and Cd from soil, thereby seriously endangering human health through diet. These toxic element levels need to be carefully monitored. Maximum levels of Pb and Cd are strictly regulated in Asian countries, especially in China; therefore, it is extremely important to develop a simple, reliable method for trace levels of Pb and Cd in rice. The allowable maximum levels of Pb and Cd in grains in EU and China are required to be below 0.2 mg/kg (Commission Regulation EC 1881/2006 and Chinese GB 2715-2016 Hygienic Standard). Graphite furnace atomic absorption spectroscopy (GFAAS) is the officially recommended technique for detection of trace elements in various food stuffs (GB/T 5009.15-2017, GB/T 5009. 12-2017 and EN 14083:2003). Food samples are usually pretreated before GFAAS analysis using various methods: microwave digestion, hot block digestion, dry ashing, and hot plate digestion. These conventional digestion procedures are usually complicated and time-consuming (2-4 hours or longer). Plus, they require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. However, fast digestion can effectively speed up the sample preparation procedure while reducing the use of corrosive reagents and the chance for contamination.

Fast Digestion Analysis of Lead and Cadmium in Rice Using Graphite Furnace Atomic Absorption

Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. In this work, a rapid, accurate method for trace-level analysis of Pb and Cd in rice grains is established and verified using fast digestion with GFAAS.
