    Abstract: Internal standard concentration is normalized as an independent parameter through measuring a buffer conductance in a system with characterized reagents and in a defined assay device. The conductivity of a fresh internal standard solution is measured whether in isolation or as part of a system that is subject to a uniform variation such as evaporation or condensation. Collected conductance measurements may be used to normalize assay signals that are dependent upon fluidic channel dimensions, such as fluorescence assay signal measurement.

    Abstract: Microfluidic devices provide substances to a mass spectrometer. The microfluidic devices include first and second surfaces, at least one microchannel formed by the surfaces, and an outlet at an edge of the surfaces. Some embodiments also include a tip surface with one or more surface features for helping guide substances from the outlet of the device toward a mass spectrometer. In some embodiments, the surface feature(s) includes a groove, which may be hydrophilic along all or part of its length. Hydrophilic surfaces and/or hydrophobic surfaces may also help guide substances out of the outlet and/or toward the mass spectrometer. In some embodiments, the outlet and/or the tip surface is recessed back from an adjacent portion of the edge. A source of electrical potential can help move substances through the microchannel, separate substances and/or provide electrospray ionization.

    Abstract: The invention herein provides improved sample injection systems and related methods to create microfluidic devices with symmetrical channel configurations that can produce relatively large sample volumes. An embodiment of the invention provides microfluidic structures with different geometries that are symmetrical from the perspective of a sample load channel and a sample waste channel, which essentially eliminates issues of time offset and other problems commonly associated with twin-T sample formation techniques. A split-injection approach and related methods of sample plug formation are therefore provided.
