No More LC: Microextraction Coupled with Direct MS Analysis

Mass spectrometry (MS) is an accepted research tool for both academic and industrial laboratories. As MS continues to gain ground in clinical and industrial testing, the requirements for high throughput, high sensitivity and high accuracy analyses put more emphasis on sample preparation. Solid Phase Microextraction (SPME) is well suited for this purpose as it requires minimal sample, provides pre-concentration of analytes, and allows for quantitative determinations. This webinar will focus on the use of microextraction devices for direct MS analysis for applications that do not require chromatographic separation. Such analysis often results in very high throughput and more immediate results in comparison to traditional methods. Several Direct MS interfaces will be reviewed. The relevant overview of the literature as applied to the direct MS analysis of microextracted samples will be presented. The presentation also will discuss in more detail the coupling of Direct Analysis Real Time (DART) with a new type of solid phase microextraction devices (known as BioSPME).
