New revolutionary injection system The Fractovap 4160 Séries is the first gas chromatograph introducing a dual capillary dedicated injection system. It in fact provides the new revolutionary on-column injector, besides the well established split-splitless injector, which definitely avoids any discrimination between low and high boiling point components contained in the same mixture.

Unique variable length temperature adjustable on-colum trapping syst This system allows the concentrais effects of the sample componer controlled. Very usefu;

compo glass capillary head space analysis. Zero dead volume true all glass system Nothing but glass capillary colt between the injection and dete; No glass lined tubing configure cause dead volumes and active centres responsible for sample decomposition of thermolabile compounds. New accurate all metal pneumatic system Accurate and precise gas regulations are ensured by all metal diffusion-proof bleeding-free pressure controllers for the dual circuit of the carrier gas, auxiliary gases and standard make-up gas fine. All lines are provided with metal shut-off valves for easier leak-check and flow-rate measurements. Interchangeable pneumatic plumbing allowing constant pressure or flow operations are also available. Ultra rapid amplifier Specially capillary column designed ultra rapid (50 msec constant time) high sensitivity and linear dynamic range electrometric amplifier to ensure reliable results even with very fast peaks.

Can any other GC be greater than this? The reply card enclosed to this journal will bring you the answer together with full details of what new technology has created and how surprisingly priced it is.
