20140110933 | LOW CARRYOVER HIGH PRESSURE FLUIDIC FITTING - Described is a fitting for coupling fluidic paths which facilitates secure and low leak rate fluid flow through a fluidic path junction such as a junction in a liquid chromatography system or other chemical analysis instrument. Fluid containing various mixtures of chemical samples can pass through the junction at high pressure with little or no trapped residue remaining in a volume at the connection. According to various embodiments, a face seal is achieved between two separate fluidic path features. In some embodiments, the sealing of the fluidic paths is aided by the use of a compliant polymer seal. The seal facilitates intimate contact between adjacent surfaces and significantly limits or prevents the entry of fluid under high pressure into an unswept volume. Thus the risk of carryover and its adverse effect on measurements is reduced or eliminated. | 04-24-2014 |
