ActiPix™ D100 UV Area Imaging System
The Paraytec ActiPix D100 UV imaging detector is now available for purchase. This keenly awaited product is set to transform UV-Vis detection technology with its increased sensitivity, minute sample requirements and wide dynamic range - unlocking completely new applications for UV-Vis absorbance detection and greatly enhancing existing applications.
Key Product Features
- Miniature UV detector that can be placed in combination with existing lab hardware, e.g. LC-MS
- Capillary-based detection, in-line or discrete allowing sub-microlitre sample volume
- High spatial resolution
- Five orders of magnitude linear dynamic range
- Powerful active pixel sensor provides real-time images
- Can be used down to 190 nm in the UV
The Paraytec ActiPix D100 is a miniature capillary UV detector, designed for on-line monitoring at a single UV wavelength, particularly for use with the separation methods of liquid chromatography and capillary electrophoresis.
The ActiPix D100 consists of a control box and a small remote sensor head containing a capillary cartridge. The remote head is designed for positioning exactly at your required detection point, and can be literally clipped in to an analysis stream. Its small size (approx 5x7x7cm) means that it is ideal for in-line detection with LC, nano-LC, LC-MS and CE.
The miniature size allows the detector to be used as a ‘clip-on’ accessory linked to existing separations instrumentation and in line with a mass spectrometer. Detection is performed at a selected wavelength by means of exchangeable filters. Light is delivered via a fibre optic coupled light source. Readout of signals on the active pixel sensor and absorbance calculations are carried out at MHz rates, with all processing done in hardware on custom electronic assemblies. Processed data is output in real-time to computer using an industry-standard high-speed serial data link.
