TRANSEPT® IV INTERFEROMETER
The Analect FTIR and FT-NIR systems were developed to provide the most accurate and reliable access to the rich chemical information contained in the vibrational spectra of organic chemicals. The use of interferometer-based spectroscopy provides great benefits in accuracy and sensitivity due to its laser referencing and high optical efficiency. The use of the Transept® IV interferometer brings these well recognized benefits to the field of process analysis by improving mechanical and thermal stability over typical laboratory based designs.
Extremely wide frequency coverage
The two basic models of the interferometer each cover a very wide portion of the infrared spectra. The mid-IR systems cover from 450 to 7000 cm-1 ranging from the fundamental vibrations to the first overtone and combination bands. The near-IR systems cover from below 3000 to 12000 cm-1 providing access to all regions of the near-IR spectrum. This region also can allow remote multiplex spectroscopy with fiber optic cables.
Instrument to Instrument Calibration Transfer
The use of a stable laser and a highly reproducible optical system eliminates the need to re-calibrate instruments after source replacement or other service operations. It also allows the use of models built on laboratory instruments to be used on process analyzers without elaborate calibration transfer operations.
Ability to operate in harsh process environments
Due to the fundamental stability of the interferometer design, process analyzers may be sited to suit the application rather than to baby the analyzer hardware. Tight temperature control of the interferometer is not required for highly reproducible results.
DIAMOND 20 LABORATORY FTIR / FTNIR SPECTROMETER SYSTEMS
All Diamond 20 systems feature the permanently aligned, low maintenance Transept® IV interferometer for repeatable results day after day, year after year.
The DCM400 Data Collection Module drives the interferometer with adaptive digital servo control and laser quadrature for positive position reference. Analog data from multiple detectors is digitized using a high accuracy, true 18-bit ADC. An industry standard ethernet port provides high speed communications with the Analyzer PC.
The full-size sample compartment has an internal focussed beam with a 2x3 slide mount for use with many typical sampling accessories. An external collimated beam and the use of the patented, high-efficiency Optibus® beam transfer system permit the use of essentially any sampling accessory, or the addition of multiple sampling accessories - including launching into fiber optically coupled NIR accessories.
A DTGS pyroelectric detector is standard, with a full line of optional detector modules to optimize the performance of your configuration, including thermo-electrically controlled DTGS, MCT, InAs or InGaAs, and liquid nitrogen cooled MCT detectors.
