  • Description

    •GCxGC provides high peak capacity by trapping compounds eluting from the first chromatographic column and then systematically injecting them into the second column to obtain the second separation.
    • LECO's LN2 modulator delivers the ability to modulate these volatile analyses.
    •The Pegasus 4D, data acquisition rates of 100 to 500 spectra/second are commonly utilized, giving sufficient data density to obtain spectral deconvolution of the chromatographic peaks, using acquired data.
