FT-NIR Analyzer - MPA Multi Purpose FT-NIR from Bruker

Choosing the best possible sampling method is crucial when solving a specific analysis task. With the MPA multi purpose FT-NIR analyzer from Bruker, you have a complete solution at hand for your method development. The modular and compact instrument can easily be adapted to your needs. If at a later stage new applications arise, simply have the required sampling tool added; all combinations are possible at any time.

The robustness of the instrument allows it to be used in the laboratory and factory floor. The MPA can be connected to your laptop via Plug & Play Ethernet and can even be placed on a utility cart to improve its mobility.

The MPA offers everything you need for the analysis of liquids, solids, powders and tablets. Powerful accessories like the automated 30-position sample wheel, which can be used for vials and tablets of all shapes and sizes, the sample rotator for the integrating sphere or up to two different fiber probes help you to achieve high sample throughput with excellent precision.

Transmission geometry for near-infrared (NIR) spectroscopy is ideal for pharmaceutical tablets as it samples a volume whereas reflectance NIR samples the surface of solids. MPA's transmission head can be combined with autosampling unit and optional tablet holders. Selection of the different measurement accessories of the MPA is completely software controlled, without the need for any manual adaptation.

Hassle-Free Maintenance

MPA spectrometers are designed to be easily maintained by the user, thereby decreasing downtime and maintenance costs. Permanent on-line diagnostics continuously monitor the instrument and advise the user of any problems. Consumable items such as the laser and the light source are designed for a long life, but if they need to be replaced, the system informs the user of the failure and automatically offers on-line help for the replacement procedure. The consumables are pre-aligned and can be easily and quickly changed. The color display keeps you informed of the selected sampling tool and the status of your instrument. Any potential failure in the internal instrument test will be displayed as well as required maintenance operations such as changing the desiccant cartridge.


All optical components installed in the MPA are permanently monitored by the online diagnostic system, PerformanceGuard™, which makes sure that your spectrometer operates correctly. A status light on the control panel and within the OPUS software informs the user of the current instrument status. Whenever a component is out of specification, the user is notified immediately.

Method Development

The MPA with its various measurement options is the ideal tool for sophisticated method developments. Initially it is often not obvious which sampling method is the best for the given task. With the MPA, simply try out several methods and compare the results. Liquid samples can be measured in the sample compartment using disposable vials or cuvettes, directly in their container using the fiberoptic probe or even in cups with the integrating sphere. Compare the composition of pharmaceutical substances in bulk form with the probe and then manufactured as tablets using the transmission unit or the integrating sphere.
