Abstract:
A quick connect high pressure liquid chromatograph fitting assembly for coupling first and second analytical miniature fluid conduits, comprising:(a) a first fitting defining a central passage adapted for receiving therein a first analytical miniature fluid conduit defining an internal diameter of no greater than 0.040 inch, the first fitting defining at least one first radial engaging surface;(b) a second fitting defining a central passage adapted for receiving therein a second analytical miniature fluid conduit defining an internal diameter of no greater than 0.040 inch,(c) a polymeric sealing element;(d) a nut provided on the second fitting, wherein the nut defines at least one second radial engaging surface, wherein the nut is selectively rotatable less than 360.degree. relative to the first fitting to engage the first and second engaging surfaces to compress and seal the polymeric sealing element between the first and second fittings for fluid flow communication between the first and second analytical miniature fluid conduits; and(e) a biasing member engageable between the first and second fittings to bias the second fitting towards the first fitting upon engagement of the first and second fittings, said quick connect high pressure liquid chromatograph fitting assembly defining a zero dead volume fluid path for coupling said first and said second analytical miniature fluid conduits and being capable of withstanding a maximum internal fluid pressure of greater than 6000 p.s.i..
