A spray nozzle, systems and methods for cleaning at least one optical fiber end face of an optical fiber connector. The nozzle includes a housing body with a first end portion and a second end portion. A discharge passage carries an atomized mixture of cleaning fluid and positively pressurized air from the first end portion to a discharge opening at the second end portion. A vacuum return passage communicates with the discharge passage proximate the second end portion. The return passage receives the atomized mixture of cleaning fluid and positively pressurized air as well as contaminants removed from the optical fiber end face. A portion of the atomized mixture of cleaning fluid and positively pressurized air is diverted from the discharge passage to control the amount of the atomized mixture being directed at the optical fiber end face.

The method and system according to preferred embodiments of the present invention allows an effective delivery of aerosolized medicament (e.g., a surfactant) to the patient's lungs. According to a preferred embodiment, the method of the present invention provides an efficient delivery of the aerosol medicament (possibly breath synchronized). A glass vial in which medicaments are usually stored and shipped is used directly as a component of the system. Its function in the system is that of an intermittently pressurized chamber that can inject the surfactant into the catheter of the atomizer device. According to a preferred embodiment the delivery can be done in phase with the beginning of each inspiration. The main elements of the system are: a source of compressed gas, the already mentioned medicament vial, a catheter, and optionally means to detect the breathing pattern and a control unit.

A dispersant system comprises a plurality of taggant vessels, each having a taggant that corresponds to a position in a tag string and a computer controller convert the tag string into a selection of a taggant set while computer-controlled valves allow or block a flow of taggants to a manifold output tube. From the output tube, a mix of the taggants flow to form a dispersant formed according to the tag string. A nozzle disperses the dispersant onto an object to be tagged, possibly atomized with air. The taggant can comprise a DNA taggant comprising a static portion and a dynamic portion that is unique to each tag string position. Tag strings for adjacent lots might have a low Hamming distances to reduce cross-contamination and/or have redundancy for error detection and correction and selected so that consumption of taggants evens out over the plurality of taggant vessels.

Provided is a sample pretreatment device configured to apply, to the surface of a sample, a solution in which a predetermined substance is dissolved or dispersed. In order to properly and efficiently unclog a nozzle due to the deposition of the crystal of a matrix substance, the device includes a spray unit (3) including a solution tube (32) for the solution to pass through, a gas tube (33) for a spray gas to pass through, and a nozzle part (30) configured to spray the solution arriving at the terminal end of the solution tube by ejection of the spray gas through the gas tube, as well as a cleaning liquid supplier (4, 41) configured to put a cleaning liquid on an opening of the nozzle part from outside the spray unit.

A system for producing a high precision blended gas product (BGP), the system comprising: a supply of a volatile analyte in liquid form; a supply of an inert carrier gas; a supply of at least one diluent gas; an analyte gasifier (AG) subsystem for receiving the volatile analyte in liquid form, nebulizing the volatile analyte and mixing the nebulized volatile analyte with the inert carrier gas so as to form an analyte gas stream (AGS); and a gas mixer (GM) subsystem for receiving the AGS from the AG subsystem and mixing the AGS with the supply of at least one diluent gas so as to produce the BGP, wherein the GM subsystem comprises: a gas analyzer (GA) for receiving the AGS and analyzing the same; a gas proportioner for receiving the AGS from the GA, receiving the at least one diluent gas, and proportioning the AGS and the at least one diluent gas based on the results of the GA so as to provide a proportioned AGS and a proportioned at least one diluent gas; and a gas mixing chamber for receiving the proportioned AGS and the proportioned at least one diluent from the gas proportioner so as to produce the BGP.

To provide: an atomizer that allows a sample liquid to be made into minute droplets stably and that inhibits clogging of an aerosol gas outlet by salting out or the like when atomizing a sample containing a high density matrix; a sample introduction unit that includes the atomizer; and an analysis device. An atomizer includes: a liquid supply tube that has a first channel in which a liquid can circulate and that has, on one end, an outlet to spray the liquid; and a gas supply tube that encloses the liquid supply tube with a gap therebetween, that has a second channel in which a gas can circulate, and that has, on one end, an outlet to spray the gas. The second channel is defined by the outer circumferential face of the liquid supply tube and the inner circumferential face of the gas supply tube and has a narrow portion upstream of the outlet.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed.
