 Request for information
The CDIPDA is a PC card Spectrometer for the ISA-Bus or in an external housing with USB interface. The optical block is totally sealed and unremovably fixed to the detector. Thus, the instrument has an unsurpassed wavelength stability. There is no recalibration ever needed. The detector has a high signal-to-noise ratio of 12000:1. Combined with the integrated 16 Bit A/D converter and an internal detector linearisation a high dynamic range can be reached.
The use of fiber optics and probes as well as the selection of the proper wavelength range provide the flexibilty needed for all kinds of measurement such as reflectance, transmission and absorbance.
In addition to the CDISPEC software that is included in delivery, a GRAMS32 package and a MyInstrument driver are available optionally. Using the driver the spectrometer can directly run under GRAMS32 software. This allows you to build your chemometric models for quantitative or qualitative analysis easily.
Should you have questions concerning the technical specification; our application scientists will be pleased to consult you.
