DTU National Food Institute wants to procure a LECO Pegasus BT 4D TOF Mass spectrometer with a cryogen free thermal modulator and an L-PAL3 autosampler with headspace. The modulator is integrated in a Agilent 7890B gas chromatograph and the TOF MS. The TOF MS can scan from 0-1500 amu and with a scanning speed of up to 500 spectra per second, the instrument is very suitable for GCxGC analysis. The modulator oven can independently be temperature programmed during the GC-run as well as the modulator time between 1s and 65s.
The ion source is open and with a ‘StayClean’ design. MS vacuum system can handle column flow up to 5 ml/min.
The Agilent 7890B GC has a split/splitless injector and has an extra FI-detector installed.
LECO ChromaTOF software is capable of controlling the entire system and has an advanced, yet easy to use, deconvolution function for data management of GCxGC data. Software license for both instrument and off-line data handling. NIST 17 MS library is included.
