How does the Levy* Signature GC provide these benefits? 
We start with the most advanced GC in the world, the Agilent 6890N, but that’s just the beginning.  A host of carefully selected and expertly installed hardware additions result in the consummate GC package.  These added features, chosen and implemented personally by Dr. Joseph Levy are based on his 26 years of practical experience.  Dr. Levy, a consultant to Tovatech, is widely recognized as one of the foremost GC specialists, trainers and troubleshooters in the world.  Dr. Levy guarantees that the Levy Signature GC will achieve optimum performance.

Optimized inlet
The inlet is typically the most problematic component of a GC. Customized modifications enhancing both performance and ease of maintenance include:

• Temperature programmable split/splitless inlets with solvent venting massively enhance sensitivity.
• EZ twist top inlet allows for trouble-free maintenance with easy access to the inlet liner.  Change inlet liners easily.
• Optimized and deactivated glass wool liners provide adequate buffer volume to allow for solvent expansion in the inlets.
• Higher inlet pressures help minimize residence times of vaporized analytes and compress vapor clouds providing enhanced transfer to the column.

Conditioned application-specific columns
The proper conditioning and optimization of capillary columns will guarantee easy method implementation.  Moreover, proven steps in successful capillary column installation will eliminate problems associated with excessive analyte diffusion that promote peak distortion.

Streamlined preventative maintenance
The development of EPC (electronic pneumatic control) has given GC the greatest precision capability in history.  However, proper preventative measures are required to safeguard this precision.  The Levy Signature installation specialists will familiarize the users in doing these very important procedures.  The leak test kit allows for easy preventative and diagnostic tests to assess all of the possible leak points in the entire inlet body as well as the EPC flame ionization detector module. 

Complete package: Installation, training, technical support, service
With the Levy Signature guarantee you know your GC will be customized for your application, thoroughly tested, and expertly installed in your laboratory.  The team installing and implementing the system in your lab will be personally trained and certified by Dr. Levy.  You will have ongoing technical support and training, in addition to a warranty and optional service contract.
