Leco massspectrometers

Leco’s mass spectrometers are all Time-Of-Flight (TOF) analyzers. This allows high scanning speeds (up to 500 complete scans/sec and can therefore be used for general GC systems or two-dimensional (GCxGC) GC analysis.

Common to all systems is the “Open source” ion source which in practice has proven to require little maintenance and therefore makes the mass spectrometers very reliable in daily operation.

Because of the TOF analyzer, the system always runs in “full scan” mode without loss of sensitivity.


The ChromaTOF software is common for the management of all systems, from Pegasus BT to GCxGC-HRT, and on the Riva GC meetings referred to as “The beautifully comprehensive software”.

It is robust, covers all platforms and has all the tools for both research and routine analysis, including a very powerful deconvolution algorithm.

Therefore, no additional learning is needed when going from one type of system to another. Speciel for GCxGC (comprehensive GC).

Especially for GCxGC (comprehensive GC) Leco’s total integration of GCxGC-MS and the software is unique.

There are other manufacturers who produce the same type of GCxGC systems, but the combination of the high scanning speed of the TOF, the robust system and not least the robust software, we consider Leco’s systems to be clearly the best on the market.

Leco’s GCxGC systems are available on Leco Pegasus HT-C and Leco Pegasus HRT platforms.
