The invention relates to a method for monitoring a container treatment installation which has a filling apparatus for filling containers and a closure apparatus for closing containers. The method involves filling a container with a filling material using the filling apparatus and measuring a concentration of a gas in the filling material of the filled container using a measuring device, wherein the filled container is removed in order to measure the concentration upstream of the closure apparatus or the concentration is measured upstream of the closure apparatus. Advantageously, the method allows the low-oxygen filling by the filling apparatus to be able to be monitored in a selective manner.

An adapter for use in monitoring the deterioration of an oil insulated transformer due to pyrolysis that allows for an alarm to be generated at the desired ppm values is provided. The adapter is configured to sample the headspace of the main transformer tank as well as the adjacent compartments of a transformer and pass it over a common sensor to check for gases indicative of pyrolysis. During this constant monitoring process, the device will alert the end user when there is an increase in monitors gases. This will allow the owner to take the transformer off line and perform other diagnostic tests to determine the extent of damage to the equipment.

A dew point sensor arrangement includes sensing and dry gas source conduits coupled to a dew point sensor. A sensing valve with a sensing valve member couples the sensing conduit to the dew point sensor. A drying valve with a drying valve member couples the dry gas source conduit to the dew point sensor. The sensing valve member fluidly separates the sensing conduit from the dew point sensor in a sensing valve member closed position, the drying valve fluidly couples the dry gas source conduit to the dew point sensor in a drying valve member open position, and the drying valve member moves to the drying valve member open position when the sensing valve member moves to the sensing valve member closed position to dry the dew point sensor using dry gas provided through the dry gas source conduit. Semiconductor processing systems and dew point sensing methods are also described.

Embodiments herein include a method for detecting a brain condition in a subject. The method can include obtaining a breath sample from the subject and contacting it with a chemical sensor element, where the chemical sensor element includes a plurality of discrete graphene varactors. The method can include sensing and storing capacitance of the discrete graphene varactors to obtain a sample data set and classifying the sample data set into one or more preestablished brain condition classifications. Other embodiments are also included herein.

The present disclosure relates to methods, devices, and systems for measuring nitric oxide released from a material. For example, a method of measuring nitric oxide release from a material can include introducing a continuous flow of a carrier gas into a sample holding chamber via a carrier gas inlet at an effective flow rate, introducing an amount of the nitric oxide releasing material into the sample holding chamber via a separate sample inlet to contact the continuous flow of the carrier gas, directing the carrier gas and released nitric oxide out of the sample holding chamber via a nitric oxide outlet toward a nitric oxide detector, and quantifying an amount of released nitric oxide using the nitric oxide detector.

The present invention relates to a gas collection device, and provides a gas collection device for collecting gas that is generated as microorganisms are cultured in a super absorbent polymer product.

Embodiments of a mobile carrier monitoring apparatus are disclosed. The apparatus includes one or more mobile carriers configured to receive items being manufactured in its interior and configured be moved by a transport system to multiple positions within a manufacturing facility. A mobile carrier control system is positioned in the interior or on the exterior of each mobile carrier, as are one or more sensors that are coupled to the mobile carrier control system. A communication system is positioned in the interior or on the exterior of each mobile carrier and communicatively coupled to the at least one sensor and to the mobile carrier control system, and an electrical power system positioned in the interior or on the exterior of each mobile carrier and coupled to deliver electrical power to the mobile carrier control system, to the one or more sensors, and to the communication system. Other embodiments are disclosed and claimed.

A sample extraction device and a desorption device for use in gas chromatography (GC), gas chromatography-mass spectrometry (GCMS), liquid chromatography (LC), and/or liquid chromatography-mass spectrometry (LCMS) are disclosed. In some examples, the sample extraction device includes a lower chamber holding a sorbent. The sample extraction device can extract sample headspace gas from a sample vial by placing the sorbent inside the vial and creating a vacuum to increase recovery of low volatility compounds, for example. Once the sample has been collected, the sample extraction device can be inserted into a desorption device. The desorption device can control the flow of a carrier fluid (e.g., a liquid or a gas) through the sorbent containing the sample and into a pre-column and/or a primary column of a chemical analysis device for performing GC, GCMS, LC, LCMS, and/or some other chemical analysis process.

A method is provided for obtaining a product sample from a vacuum vessel by using a system including a first valve arrangement, a second valve arrangement and a sample receiver connected to the first valve arrangement and the second valve arrangement. The method includes opening the first valve arrangement to provide fluid communication between an upper volume of the vacuum vessel and the sample receiver, opening the second valve arrangement to provide fluid communication between a lower volume of the vacuum vessel and the sample receiver, closing the first valve arrangement and the second valve arrangement, opening the first valve arrangement to provide fluid communication between surrounding atmosphere and the sample receiver, and opening the second valve arrangement to collect the product sample.
