Patent number: 8322577Abstract: A plunger for a syringe used to inject gas and liquid chromatography samples has an end portion surrounded by a flexible sleeve. The sleeve forms a seal in the bore of a barrel traversed by the plunger, the bore being in fluid communication with a cannula attached to the end of the barrel. The plunger has an end surface that is exposed and is flush with an annular end surface of the sleeve. The plunger end surface, and not the sleeve, contacts the cannula upon injection and avoids imposing cyclical hoop stresses on the barrel which tend to crack the barrel after a finite number of cycles. In a further embodiment, a thin layer of sleeve material covers the end surface of the plunger. The thin layer avoids inducing significant barrel stress.Type: GrantFiled: April 24, 2009Date of Patent: December 4, 2012Assignee: Agilent Technologies, Inc.Inventor: Ponna Pa

Patent number: 8280211Abstract: An all-optical sampling device using four-wave mixing in third-order optically nonlinear materials is described. The four-wave mixing based sampler comprises a waveguide combiner, which adds a gate optical signal to a signal of interest to be sampled. In a four-wave mixing region, a sampled signal at the output optical frequency is produced. All of the optical signals are sent to a passive optical filter, which preferentially discards the gate and signal optical frequencies, but preserves the sampled signal at the output optical frequency. The sampled signal at the output optical frequency can be observed, displayed, recorded or otherwise manipulated.Type: GrantFiled: January 19, 2010Date of Patent: October 2, 2012Assignee: University of WashingtonInventors: Tom Baehr-Jones, Michael J.

Patent number: 8258476Abstract: Radiation detection systems and methods. In one approach, optical radiation can be detected by using the radiation to be detected as input to a high index contrast waveguide modulator that modulates a wavelength of light that falls within the detection band of a detector. In another approach, the optical radiation that is to be detected is combined with a high power CW boost mode signal in a waveguide, and the sum and/or difference frequencies are detected. In either approach, one can use grating couplers to couple the optical radiation of interest into a waveguide.Type: GrantFiled: November 25, 2009Date of Patent: September 4, 2012Assignee: University of WashingtonInventors: Tom Baehr-Jones, Michael J.

Patent number: 8247784Abstract: A novel ion source for ambient mass spectrometry (switched ferroelectric plasma ionizer or “SwiFerr”), which utilizes the ambient pressure plasma resulting from a sample of barium titanate [001] whose polarization is switched by an audio frequency electric field. High yields of both anions and cations are produced by the source and detected using an ion trap mass spectrometer. Protonated amines and deprotonated volatile acid species, respectively, are detected in the observed mass spectra. Aerodynamic sampling is employed to analyze powders of drug tablets of loperamide and ibuprofen. A peak corresponding to the active pharmaceutical ingredient for each drug is observed in the mass spectra. Pyridine is detected at concentrations in the low part-per-million range in air. The low power consumption of the source is consistent with incorporation into field portable instrumentation for detection of hazardous materials and trace substances in a variety of different applications.Type: GrantFiled: July 29, 2010Date of Patent: August 21, 2012Assignee: California Institute of TechnologyInventors: Evan L.
