ATAS GL is producer of the World most versatile GC injector. The OPTIC 3 is a multi mode inlet for gas chromatography. With the OPTIC 3 we can handle techniques like pyrolysis GC MS (py GCMS), large volume injections (LVI) and thermal desorption (TD). We can handle both solid and liquid samples for pyrolysis. Also for thermal desorption we can put a solid sample into our liner.
