LECO Corporation's Pegasus 4D GCxGC-TOFMS provides four dimensions of analytical resolution for a more comprehensive analysis of complex samples such as biofuels. The enhanced peak capacity of GCxGC separation helps eliminate co-elution issues associated with one-dimensional GC analysis of biofuel sample types. In addition to the increase in chromatographic resolution, the use of TOFMS provides users with the ability to acquire full mass range spectra without sacrificing speed or sensitivity, according to the company. Standard with the TOFMS instrument, LECO's ChromaTOF operating software includes a variable modulation feature that allows users to modify modulation setting within each chromatographic run to further maximize chromatographic resolution.
