A novel gas injection valve for injecting discrete charges of gas into a mobile phase or carrier stream is provided. Injection valves of the invention comprise a plurality of microvalves capable of receiving gas at different pressures and emitting discrete charges of gas at approximately the same pressure. The invention further provides for parallel injection valve arrays capable of injecting multiple samples substantially simultaneously and a method of injecting discrete gas samples at a controlled pressure to a high-resolution gas chromatograph.

Injection valve array

The invention relates to a device for detecting input radiation such as X-rays, &ggr;-rays, ionizing radiation or fluorescent and low-level light. The device has at least one detection element comprising a sensor component (scintillator) for converting the input radiation into photons (scintillation light) in the UV, visible or IR part of the electromagnetic spectrum and an optical amplifier component which receives the light converted by the sensor component, forwards it for further processing and amplifies it at the same time. According to the invention, the amplifier component comprises at least one optical waveguide (,) whose material is optically pumped to amplify the scintillation light (,).
