Abstract: The present disclosure provides an apparatus for sampling at least one analyte from a sampling fluid. The apparatus includes: a solid-phase microextraction (SPME) sampling instrument. A connector is attached to the SPME sampling instrument and is coupleable to an aerial drone. The apparatus includes a protective cover that is sized and shaped to at least partially surround the SPME sampling instrument. The SPME sampling instrument and the protective cover are movable in relation to each other between a protecting configuration and a sampling configuration. The SPME sampling instrument and the protective cover are (i) biased in the protecting configuration when the density of the fluid surrounding the SPME sampling instrument is less than the density of the sampling fluid; and (ii) biased in the sampling configuration when the density of the fluid surrounding the SPME sampling instrument is equal to or greater than the density of the sampling fluid.

Abstract: The present invention describes several embodiments of a device that allows for the supporting, storage and deployment of large surface area thin film solid phase microextraction (TF-SPME) chemical samplers from within a sample fluid carrier. The utility of said supporting device originates from the process by which the extraction surface is stabilised within a sample carrying fluid for the extraction of chemical molecules from said sample carrying fluid. The device is also characterized by having a seating cavity, and moving mechanism or cap that can switch the supported TF-SPME chemical sampler between an open, sampling position or closed storage position.

Abstract: Applicants' teachings relate to a method and device to extract components contained in a fluid. More particularly, the applicants' teachings are directed towards a method and sampling device for quick extraction of targeted components from their in vivo surroundings. In accordance with various embodiments of applicants' teachings a sampling device and method to extract components, such as, for example, analytes, from a fluid is provided. The device is interfaced with a fluid source, such as, for example, but not limited to, a circulatory system of an animal, to enable extraction of target molecules with minimal loss of fluid (e.g., blood) to the source. The device facilitates an interface between the circulatory system of an animal and a suitable sampling probe such as, for example, a solid phase microextraction (SPME) probe. The targeted compounds are desorbed in small volumes of solvents that can be analyzed with highly specific instruments.

Abstract: Use of calibrant in extraction phase is described for quantification of components of interest in samples in laboratory application as well as in on-site monitoring. This approach is particularly useful for in-vivo investigation of living system.

Abstract: Improved apparatus is disclosed for carrying out axially illuminated laser induced fluorescence whole-column imaging detection in the capillary isoelectric focusing of proteins. The separation capillary was made of low refractive index Teflon conditioned with methylcellulose to reduce electroosmotic flow and a small amount of high refractive index organic solvent (glycerol) was added to the sample mixture. It was found that an axially directed laser excitation beam was propagated essentially with total internal reflection, so that minimum interference arose from stray light or from scattering light originating from the wall of the capillary. With the naturally fluorescent protein R-phycoerythrin, a concentration detection limit LOD 10?11 M or mass LOD 10?17 Mo was obtained.

Abstract: A device for carrying out solid phase microextraction on-site is a tubular member having one closed end and one open end with an extracting surface within said tubular member. The extracting surface can be an extracting phase coating extending over a zone within the tubular member. The tubular member is mounted in a housing with an airtight cavity. A method of operation of the device is also provided. The solid phase microextraction device facilitates the ultimate goal of chemist to perform analysis on-site at place where a sample is located rather than moving the sample to laboratory, as it is a common practice in many cases at present. This approach eliminates errors and reduces the time associated with sample transport and storage and, therefore, it results in more accurate, precise and faster analytical data.

The micro cartridge is elongated and has one pointed end to fit into the injection port of a suitable analysis instrument where the components of interest are desorbed. The cartridge has two ends that are covered by removable closures and preferably has a diameter of less than 1 millimeter. The cartridge can be used with micro machine components and components made using nano technology.
