Systems and methods for monitoring analytes in real time using integrated chromatography systems and devices. Integrated microfluidic liquid chromatography devices and systems include multiple separation columns integrated into a single substrate. Using such a device, parallel analysis of multiple samples can be performed simultaneously and/or sequential analysis of a single sample can be performed simultaneously on a single chip or substrate. The devices and systems are well suited for use in high pressure liquid chromatography (HPLC) applications. HPLC chips and devices including embedded parylene channels can be fabricated using a single mask process.

A diagnostic device is provided that includes a plurality of retainment regions, with the retainment regions that are separated by at least one dissolvable barrier. The retainment regions can be interconnected through at least one fluid processing passageway. A retainment region can include a container such as a retainment region, well, chamber, or other receptacle, or a retainment region such as a surface on which the material is retained. The retainment regions can include a reaction retainment region, one or more reagent retainment regions, each containing unreacted reagents, and a sample retainment region. A pressure-actuated valve can be positioned in each fluid processing passageway interconnecting the one or more reagent retainment regions with the respective intermediate retainment regions interposed between each of the one or more reagent retainment regions and the reaction retainment region. The dissolvable barrier can be a fluid flow modulator in the at least one fluid processing passageway.

An electrochemical flow cell comprises a substrate having an insulated surface, a polymer gasket integrally disposed on the surface, and a top cover disposed on the gasket. The components define a fluidic channel when assembled. An electrode(s) on the substrate surface provides for electrochemical detection of analytes in the fluid flowing over the electrode in the fluidic channel. The electrode(s) can be also integrated to the substrate. The assembly can be packaged. The flow cell inexpensive, versatile, and disposable. Small dimensions can facilitate good sensitivity and selectivity. Applications include environmental, life sciences, pharmaceuticals, and proteomics. The cell can be adapted for both detector and electrospray ionization applications.

An enclosure for generating a secondary environment within a processing chamber for coating a substrate. An enclosure wall forms a secondary environment encompassing the coating source, plasma, and the substrate, and separating them from interior of the processing chamber. The enclosure wall includes a plurality of pumping channels for diverting gaseous flow away from the substrate. The channels have an intake of larger diameter from the exhaust opening and are oriented at an angle with the intake opening pointing away from the deposition source. A movable seal enables transport of the substrate in open position and processing the substrate in closed position. The seal may be formed as a labyrinth seal to avoid particle generation from a standard contact seal.
