OF

We offer a wide selection of superior quality products designed to work with your PerkinElmer instruments. Our precision designed products deliver the peace of mind that comes from knowing that you’ll get the results you need. Choose from our variety of hollow cathode lamps, nebulizers, graphite furnace autosampler supplies, HGA & THGA graphite components, and flow injection system supplies.

Bulbs & Lamps

For both analytical or biological analyses, we provide the highest quality bulbs and lamps to help with your testing needs.
  • Bulbs: For the optimal performance from our high content imaging, digital pathology, and tissue imaging systems, we have the right bulbs for your instruments.
  • Lamps: From AA lamps, like single and multi-element hollow cathode (HCL) and electrodeless discharge (EDL), to LC and UV deuterium, tungsten, and xenon lamps, we have what you need to perform your analysis. Each lamp is designed to match the performance of your instrument and is tested to meet our high standards.

Flow Injection System Supplies

We offer a complete line of genuine replacement parts for the FIAS, FIMS and MHS systems. Keeping your system in good working order by using only the best replacement parts is the first step in assuring quality analytical performance. Regular maintenance and/or replacement of consumables such as tubing, connectors and adapters will maximize the lifetime and productivity of your flow injection system.

Graphite Tubes

The production of high-quality graphite components requires stringent quality control. To ensure high quality and consistency, a specific grade of high-density base graphite material has been developed for PerkinElmer’s exclusive use. This base graphite material is used for the manufacturing of all PerkinElmer graphite tubes. Selection and careful control of raw materials are extremely important. The composition and the microstructure of the base graphite material determine the specific resistivity of the tube and its heating characteristics. When you purchase graphite supplies from PerkinElmer, you get the results of our many years of experience with quality graphite parts.

Nebulizers

All of our nebulizer assemblies are adjustable for optimized performance and include easily-interchanged capillary assemblies for simple, reduced-cost maintenance. Our nebulizers are manufactured to exacting tolerances to provide maximum sensitivity. Universal, or, ‘standard’ nebulizers are less expensive than the corresponding high-sensitivity nebulizers and provide a lower level of sensitivity. The universal, or, ‘standard’ nebulizers typically provide better precision and reduced ‘carryover’ interference when used with solutions that contain high dissolved solids content of higher analyte concentrations.

Sample Cups

Graphite furnace sample cups are of heavy-duty construction to prevent cracking or tipping. Their conical design allows for use of nearly the entire sample. With a diverse choice of materials, we have every solution your labaratory may need.

    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. 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.

    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.
