Top 7 Things You May Not Know About Microwave Sample Prep

1. Laboratory microwave digestion systems were first introduced in 1986 at the Pittsburgh Conference in Atlantic City, NJ.

2. US Customs and Border Protection uses microwave digestion to prepare pistachios for analysis to determine their geographic origin.

3. Microwave digestion systems are used routinely for preparing consumer products, including children’s toys and jewelry, for metals analysis, such as lead and cadmium, to ensure kids’ safety.

4. The first commercial microwave sample preparation systems only used power and time parameters to control digestion conditions. Temperature and pressure control were introduced later.

5. The vent and reseal design of the first microwave digestion vessels only held pressures of 100 psi compared to the 1000 or more psi that many vessels today can withstand.

6. It took six years for the US Environmental Protection Agency to promulgate Method 3051 (digestion of sediments, soils, and sludges for metals analysis), which is the most popular microwave-assisted USEPA method.

7. Microwave-assisted extraction can be used to determine the presence of polycyclic aromatic hydrocarbons (PAHs) in catfish.
