International Classification:

B01L 100

US Classification:

422 63, 422104, 422134

Abstract:

Apparatus and methods are disclosed for controlling flow of fluid inside a chamber. A device comprises a chamber comprising at least one wall, a first opening for introducing a fluid into the interior of the chamber, and a second opening opposite the first opening. The at least one wall of the chamber is designed to provide a contracting section, a section having substantially constant cross-sectional area and a diffusing section through the chamber from the first opening to the second opening. The device may be employed as a gas outlet in a reaction chamber for conducting reactions where it is desired to control the internal atmosphere of the reaction chamber. The apparatus may be employed in the manufacture of biopolymers on the surface of a support such as an array of biopolymer features on the support. Also disclosed is a holding element for a support wherein the holding element is a low drag body.

US Classification:

73 2901, 7333504, 73 2905, 324689

Abstract:

A system for monitoring water concentration in gaseous sample is disclosed. It is readily applicable in the synthesis of biopolymer arrays/microarrays involving the use of water-sensitive reagents. A flow cell is provided in which a capacitance sensor is placed separate from a production or synthesis environment. Sample and dry gas may be provided to the flow cell via conduits and valves or a manifold system. Dry gas, such as N, is used to dry the sensor or simply to maintain it in a dried condition. The same gas may be used to drive an optional venturi pump to draw sample for measurement into the cell from the synthesis environment.

Abstract:

Methods are disclosed for synthesizing a plurality of compounds on the surface of supports. The synthesis comprises a series of cycles of steps in which reagents for conducting the synthesis are deposited on the surface of the support to form the chemical compounds. At least one physical parameter of the deposition varies between cycles The method comprises conducting the synthesis in at least two sets of cycles, arbitrarily designated as a first set and a second set. Each cycle comprises at least one step of depositing reagents on a surface by means of droplet dispensing elements that traverse the surface of the support. At least one, and desirably all, of the following deposition parameters are employed as indicated: The number of times of repetition for a step of depositing reagents in at least one cycle of the second set is less than the number of times of repetition for a corresponding step in at least one cycle of the first set. The rate of deposition in at least one cycle of the second set is slower than or equal to the rate of deposition in at least one cycle of the first set. The rate of traversal of the dispensing elements over the surface of the support in at least one cycle of the second set is greater than such rate of traversal in at least one cycle of the first set.

Abstract:

A method and system for quantifying and correcting spatial-intensity trends for each channel of a microarray data set having one or more channels. The method and system of one embodiment of the present invention selects a set of features from each channel of the microarray data set. Based on the selected set of features, a surface is used to determine the intensities for all features in each channel of the microarray data set. Spatial-intensity trends within the microarray data set are quantified, based on the surface to the intensities for each channel of the microarray data set. After the surface has been determined, the spatial-intensity trend can be removed from the microarray data set.
