With this technology combination practically all common types of plastics, regardless of color, size, structure (films, foils, granules, solid, foamed, carpets and textiles) can be identified together with their additive elements like fire retardants and heavy metals. For sample preparation, to remove dust and dirt or paintings the sample surface can be easily cleaned by scratching with a knife.
The basic principle of the NIR technology is the diffuse reflection spectroscopy whereby characteristic absorption behaviors of different polymer types are used in that spectral region. The polymer sample is radiated with a infrared light and the reflected light of the measuring place is analyzed using a near infrared detector array. The basic principle of the Sliding Spark technology is the thermal vaporization of a small amount of the plastic surface using a train of defined high-current sliding sparks. The material components in the spark plasma are vaporized, atomized and activated to emit radiation.
For plastic identification one of the measuring pistols is simply pressed on to the analysis sample. The measurement begins by pressing the start button on the pistol grip. After one second an integrated color TFT-screen displays the recognized polymer. The measuring pistols are connected with a 2 m cable each to the instrument. The optical signals are transported via fiber cable to the spectrometer systems. Parameter settings can be set by using an integrated touchscreen. Additional connections like an USB-interface allow data transfer.
Identification of different plastic types is the result of a trained pattern recognition. After the measurement of the plastic sample the optical information are processed by a neural network. The result of the calculation is a list of the most probable polymer type identified within a probability of 0 and 100%.
Additive detection is performed by the characteristic atomic emission for an element of the additive in the optical spectra. The intensities of defined spectral lines are compared with preset threshold values. An element is detected if the pre-set threshold value is exceeded. After calibration with known samples, the system enables semi-quantitative analysis of inorganic contents in the sub-% concentration range.
The software allows detailed spectra viewing, loading, saving and editing. The setting of different measuring parameters as so as the possibility to display the resulting spectra easily allows to develop own applications.
