Abstract: A device for separating one or more molecules of interest in a liquid specimen including a monolithic body defining a fractionation column. The column includes an inlet opening at a proximal end of the fractionation column; an outlet opening at a distal, opposite end of the fractionation column; a solid phase chamber positioned between the inlet opening and the outlet opening; a specimen introduction area adjacent a proximal end of the solid phase chamber; an analyte exit area adjacent a distal end of the solid phase chamber; an inlet chamber adjacent the inlet opening that tapers into the specimen introduction area; and an outlet chamber that extends from the analyte exit area to the outlet opening. A metered amount of solid phase packed within the solid phase chamber between a first porous frit and a second porous frit of the solid phase chamber.

Abstract: Systems, apparatus, methods, and kits are provided for automated mass spectrometric analysis of small volumes of liquid samples, such as biological samples. The systems, apparatus, and kits may be used in facilities where high throughput of samples, as well as reliable and repeatable assay results with little training of staff, are needed. Such facilities include hospital emergency wards.

Abstract: Embodiments of the present disclosure present novel systems, devices and methods for an automated biological sample analysis using mass-spectrometry. The time from sample introduction to the reporting of data, in some embodiments, takes a relatively short amount of time (e.g., several minutes). In some embodiments, a biological sample to be analyzed is a blood sample. For many applications, only a single drop of blood may be sufficient. Through the use of a mixture of standards with unique molecular mass, a quantitative analysis of the target analyte can be performed in a single MS run (for example), eliminating the need to create and analyze standard curves. One advantage of such embodiments may be that the system, devices, and methods can eliminate the need for batch creation since the requirement to amortize the time and effort of creating and analyzing standard curves can be eliminated.

Abstract: The invention features methods of making devices, or “platens”, having a high-density array of through-holes, as well as methods of cleaning and refurbishing the surfaces of the platens. The invention further features methods of making high-density arrays of chemical, biochemical, and biological compounds, having many advantages over conventional, lower-density arrays. The invention includes methods by which many physical, chemical or biological transformations can be implemented in serial or in parallel within each addressable through-hole of the devices. Additionally, the invention includes methods of analyzing the contents of the array, including assaying of physical properties of the samples.
