Abstract: Systems, apparatuses, kits, and methods for purification and analysis of analytes having a broad range of hydrophobicities by liquid chromatography-mass spectrometry (LC-MS). Using one set of liquid chromatography columns, one set of mobile phase buffers, and, optionally, a single ionization method (e.g., electrospray ionization), a wide range of analytes can be purified and analyzed on a liquid chromatography-mass spectrometry (LC-MS) system. LC-MS purification and analysis of analytes having a broad range of partition coefficients is accomplished by selecting LC run parameters and MS system parameters that are particular to different classes of analytes without having to make column or buffer changes or any other hardware configuration changes to the LC-MS system.

Abstract: A water vapor sensor comprises a substrate and a film of carbon nanotubes impregnated with surfactant on the substrate. The substrate is of material which is inert relative to the film.

Abstract: A sensor housing includes an inlet flow port, an outlet flow port, a flow sensing region, and a flow channel extending between the inlet flow port, the flow sensing region and the outlet flow port. The flow channel defines a flow path between the inlet flow port and the flow sensing region that is contorted in three-dimensions. The three-dimensional contorted flow path between the inlet flow port and a flow sensing region may include a particle collection region that is configured to decelerate a fluid and collect particles that are released from the fluid. The deceleration of the fluid flow and/or one or more changes in the direction of fluid flow along the contorted three-dimensional flow path may cause dust and/or other particulate matter to be released from the fluid prior to reaching a sensor in the sensing region.

Abstract: An apparatus and method for assessing adhesion of labels applied to a bottle. A label adhered to the outer surface of the bottle is split vertically to form a leading end and trailing end of the label. The bottle may be secured to a support structure and the trailing end of the bottle may be secured to a weighted structure. The bottle is suspended in a heated chamber via the support structure until the adhesive fails, causing the weighted clamp to fall within the chamber. An elapsed time to failure is determined for the bottle and compared to a benchmark time and/or metric as an indicator of how the adhesive is likely to perform during shipping and/or storing the bottle.
