Microwave extraction is becoming the choice for the extraction of a diverse array of solid matrices for organic analyte analysis by GC, GC-MS, HPLC, and other analytical techniques. Since it operates at a far higher temperature and pressure than traditional Soxlet and sonication technologies, it can be applied to a broader range of samples. One of the biggest benefits is realized in the reduced amount of time the extraction takes for multiple samples in a single extraction operation. With microwave extraction, samples are enclosed in high quality Teflon vessels together with solvent and heated to a controlled temperature with microwave power. With the flexibility of vessel options, choices of sample size, temperature/pressure, amounts of solvent, and number of samples make this an attractive technology for high-throughput sample preparation as well as the ability to process more difficult samples. This technology can also be applied to open-vessel applications depending on the matrix and substrate analyzed. One of the major benefits seen with this approach is moving to solvent-free applications.
