irSys® E: The spectrometer from TQ with the ability to be integrated into processes.

Overview

The spectrometer irSys® E is based on the well known principle of scanning grating spectrometers with electrostatic driven micromechanical scanning mirror.

 

Advantages:

  • Compact dimensions
  • Low weight
  • Short data aquisition time
  • High durability (no wear on mirror)
  • Flexible configuration for different applications

 

 

Radiation to be analyzed passes an entry slit, strikes a diffraction grating and is decomposed into its spectral components. Having passed exit slits, those spectral components reach two different detectors to be captured successively. The selection of the relevant wavelengths is done by a micro-mechanical mirror (MEMS) which leads the radiation entered to the grating while varying its angle of incidence. Using the provided software, the individual spectra of the two sensors are combined into an overall spectrum.

 

Due to the scanning method with its approximately 250 double passes per second, the spectrometer is especially suited for analysis of temporally time-constant spectra.

Software

Application software

There is a software application provided with every irSys®. This software contains functions for controlling the spectrometer and visualizes the detected spectra. There are simple and easy to use functions to display the spectra at a wavelength or wave number basis and spectral operations like offset correction or using of reference spectra.

 

 

 

 

 

The measurement data may be stored in a ASCII-file or in a common matrix. A individual configured ini-file contains the parameters for using irSys®. 

Dynamic Link Library (DLL)

For customer specific applications there is available a DLL with an easy to use API, that communicates with the application software itself. The API may be modified or tailored to customers' needs. The DLL uses the same parameters from ini-file like the provided application software.

 

Examples of use

For analysis of translucent liquids there are available transmitted light measurement configurations by using cuvettes.

 

That configurations are applicable for analysing:

  • Solvents
  • Fuel
  • Raw materials and products of chemical industry
  • Food
  • Feeding stuff
  • Fats
  • Oils
  • Sewage

Depending on the lenght of the cuvettes, it is possible to analyse characeteristics of gases like the fuel value of natural gas. The cuvettes, made of different materials like for example silica glass, should have a maximum of transparency within the wavelength range of the measurement. 

 

 

 

 

 

 

The figure shows a simple transmission optics configuration with parallel light through the sample. A halogen lamp (12V/20W type) with back side reflector for higher light efficiency delivers the lighting. The transmission cell is in the parallel light beam between two lenses. A 400 µm fiber connects the irSys® 1.7 spectrometer. There are typical samples of fuel measured with this configuration. Please see figure for details.

 

 

 

 

The application software combines the resulting spectrum from the two detectors spectra.
