Measuring Systems for Spectroscopy

Polytec PSS spectrometers provide the ideal solution to your NIR process analytics problems. Diode array detector technology combined with a transmission grating design means the devices can be used for fast and reliable data acquisition. 

The compact PSS Mobility Kit spectrometer system is ready to use at any time due to the fixed scan head with defined working distance, the rotating sample plate and the integrated reference. 

The PSS-H-A03 distance scan head is a reflection scan head that allows the user to carry out sample measurements at distances of between 150 and 600 mm. This makes it ideal for analyzing goods being measured on conveyor belts, for strip products and for similar applications. 

The PSS-H-B01 and PSS-H-B02 contact scan heads are reflection scan heads which allow you to measure samples – which are being transported through the likes of pipes, chutes and funnels – over short distances. 

The PSS-H-CR1 reflection immersible probe is the right choice for measuring liquid or viscous samples. The probe is also available in a version that is suitable for use in the food industry.

The PSS-H-CR2 reflection immersible probe can be easily integrated into pipelines or reactors. The innovative design with integrated reference enables you to control fluid media such as liquids, dispersions or pastes online. The probe can also be used for food analysis purposes.

The PSS-H-117, PSS-H-217, PSS-H-125 and PSS-H-225 fiber scan heads are used for transmission measurements (e.g. gases) or passive measurements (e.g. hot steel or glass). 

Software for simple process integration.

Special software for mobile online applications on harvesters such as combines.

Software packages for chemometric method development.

Software for system control and for data acquisition and evaluation.

Hardware driver package for convenient implementation in external software solutions

The Multiplexer solution allows the user to perform spectrometer-based measurements with several and even different probes at various points during the process. This means that different evaluation solutions can be used at these spots. 

You can choose from a comprehensive portfolio of accessories for the Polytec spectrometer systems. Polytec even individually makes single units of application-specific accessories in line with your requirements, for use in studies or series preparation operations.

The innovative transmission grating design of the PSS-M polychromator for NIR spectroscopy guarantees maximum sensitivity and extremely low scattered light levels. 

The PRS-M polychromator module for Raman spectroscopy offers superior sensitivity and a spectral resolution that covers a multitude of applications. 

Polytec PSS spectrometers provide an ideal solution to your NIR process analytics problem. Based on a transmission grating design with diode array detectors, the devices ensure fast and precise data acquisition. Flexible combinations with fiber-coupled components allow for integration in various measurement scenarios according to the user’s requirements. Highly standardized components mean that no compromises have to be made with regard to precision and user friendliness.

Different measurement situations require different probes to suit the application at hand. This is precisely why Polytec offers a selection of scan heads that can be used in direct contact with and even at a greater working distance from the goods being measured. Probes that can be immersed in the product to be analyzed are also available. Some sensors have already been combined with an illumination module and have an internal reference. Using a multiplexer system with fiber-optic switches, a spectrometer can be equipped with several probes which are used at different measurement points.

The range of solutions on offer includes software packages both for in-lab analysis and for process monitoring. For in-lab analyses, you can use PAS LABS with its comprehensive configuration options for the measurement process. The software enables quick and convenient data acquisition. For process applications, Polytec offers you customized software solutions which you can configure in many different ways – from appropriate measurement process control, to communication with the process control system. The portfolio is rounded off by compatible software packages from renowned providers for multivariate data analysis. 

The Multiplexer solution allows the user to perform spectrometer-based measurements with several and even different probes at various points during the process. This means that different evaluation solutions can be used at these spots. This instrumentation enables flexible and affordable integration in customized measurement scenarios for a wide range of applications.
