A method of forming a stream having a therapeutic concentration of nitric oxide (NO) is disclosed, along with an apparatus and system suitable to accomplish this method.

Nitric oxide generation, delivery, and monitoring system

A sampling device comprising a filter to remove particulates greater than about 10 microns, a dryer active to remove water vapor present in the air sample, a chemical scrubber active to remove contaminants from the air sample, a cold trap to capture analytes which is configurable to be put into fluid communication with a spectroscopic analyzer. A method of obtaining and analyzing a sample utilizing the device is also disclosed.

Field sampling system and method of using

A cavity ring down measurement system comprising a light source in optical communication with a detector through an optical cavity wherein the detector is in electronic communication through a gating circuit with a first integrating circuit and a second integrating circuit, controlled to obtain a ring up signal simultaneous with a ring down signal of a plurality of ON-OFF cycles over a single period of time. A process to utilize the system is also disclosed.

Simultaneous gated integrated detection device and process

A method and device for detecting explosive compounds in an air sample in which the air sample is filtered with activated carbon treated with a weakly basic solution, after which the air sample is divided into two parts, with one part being heated at lower temperatures to decompose non-explosive nitrogenous compounds and the second part being heated at higher temperatures to decompose explosive nitrogenous compounds. Nitrogen dioxide is measured in both portions of the air sample with a spectrographic detector, and the presence or absence of explosive nitrogenous compounds in the air sample is determined.

Chemical explosive detector

A cavity ring down system is optimized to precisely measure trace gases or particles in an air sample by using time sampling detection and multiple-sample averaging resulting in a high signal-to-noise ratio. In one embodiment, a cavity ring down system is programmed to measure the rise time and the fall time of the light level in an optical cavity. The cavity ring down system is programmed to integrate a plurality of sample portions during a rise time and a plurality of sample portions during a fall time (in alternate intervals) to obtain a time constant with no sample present and a time constant with sample present. The measurements are used to calculate trace gases in the air sample.
