B01D 15/08

US Classification:

210656, 2101982

Abstract:

Embodiments of the present invention are directed to methods and devices for minimizing band spreading of compositions separated by chromatographic processes. One embodiment of the present invention features a device () for holding a separation column or cartridge. The device () includes a housing () having a chamber for receiving one or more columns or cartridges. The columns and cartridges have an inlet for receiving fluid and an outlet for discharging fluid and a column axis corresponding generally with the flow of fluid from the inlet to the outlet. The columns and cartridges are suitable for performing separations in which a constant temperature is desirable. The housing () further includes a heating element for maintaining said chamber at a constant temperature. The device () further includes positioning means () for placing the column and cartridge outlet in proximity to a detector.

International Classification:

B23P 19/00

US Classification:

13731501

Abstract:

A liquid-chromatography module includes a microfluidic cartridge housing a microfluidic substrate with a channel for transporting fluid. The microfluidic substrate has fluidic apertures through which fluid is supplied to the channel. One side of the cartridge has nozzle openings, each aligning with a fluidic aperture in the microfluidic substrate and receiving a fluidic nozzle. A clamping assembly has a plunger that is movable into a clamped position and an end housing that defines a chamber. One wall of the end housing has a fluidic block with fluidic nozzles extending into the chamber. A second wall has a slot through which the cartridge enters the chamber. When moved into the clamped position while the cartridge is in the chamber, the plunger urges the cartridge against the fluidic block such that each fluidic nozzle enters one nozzle opening and establishes fluidic communication with one fluidic aperture in the microfluidic substrate.

International Classification:

B05B 15/00

US Classification:

239289

Abstract:

An apparatus for chemical separations includes a microfluidic substrate having an outlet aperture for outputting an eluent of a sample, a spray unit having an inlet to receive the eluent and an outlet to emit a spray of the eluent, and a force-applying unit. The spray unit has a deformable portion defining the inlet and having an elastic modulus that is lower than an elastic modulus of the microfluidic substrate. The force-applying unit, such as a spring, is disposed to urge the deformable portion in contact with the substrate to form a substantially fluid-tight seal.

International Classification:

G06F 116
H05K 700

US Classification:

361686

Abstract:

An industrial computing device includes a field mountable primary housing having a removable side cover to facilitate expansion. Within the primary housing there is a head board having a processor on one side. On the opposite side, there is an expansion connector adapted to receive an expansion board and at least one peripheral connector, which is coupled to the processor within the housing. The peripheral connector receives at least one PCMCIA card such that the PCMCIA card is also within the housing when plugged into the peripheral connector. The expansion board includes at least one more peripheral connector to receive at least one more PCMCIA card. The peripheral connector, the expansion connector and the side cover are oriented orthogonal to a mounting plane of the computing device. The primary housing can also include a removable front cover, which together with a top or bottom portion of the primary housing, provides an aperture for flush-mounting an I/O device in the form of an internal dongle. The dongle can include a rear cable that connects to the PCMCIA card or other device within the housing, a front connector for coupling to a field device, and a circuit coupling the connector and the cable.
