Medizin- und Labortechnik Engineering GmbH Dresden FIA system The automated analytical system is developed for determinations in laboratories performing water and environmental analysis as well as food sample analysis using standardized analytical procedures with a photometric detector. The FIA system is designed as a multichannel, easy-to-use wet-chemical analysis system which is controlled by a PC. The detection is carried out photometrically, whereby the measured data is recorded and managed with the FIAStudio software. Due to the modular setup, the FIA system can be customized to meet the specific requirements of the laboratory. Each analysis module comprises the following functional parts: - 8-Port-injection valve Step-motor driven 6-channel-peristaltic pump (long life) Photometer with 50 mm cuvette compartment and replaceable interference filter Display to show the current operating status The analysis module FIA Nexus combines proven technology with a new 50 mm photometer and stateof-the-art control electronics. The method units can be exchanged quickly and easily within a few minutes. Thus, FIA Nexus enables the sequential measurement of different parameters with a small number of samples. For a high sample throughput several FIA Nexus can be operated in parallel. Thus, several parameters can be determined simultaneously for the same sample with one run. The basic device is equipped with a 6-channel peristaltic pump. For the implementation of complex methods with digestion or enrichment, a second peristaltic pump and digestion components can be integrated. These components can also be retrofitted. The autosampler of the analyzer system can distinguish two sample trays with different types of vials. The available diluter performs an automatic dilution for off-range samples (e.g. 1:10 dilution). Due to the 8-port-injection valve two measurement ranges can be realized without modification.

Medizin- und Labortechnik Engineering GmbH Dresden The control of the one or multichannel FIA system is carried out by the Windows-based FIAStudio software. In addition, it is used to record, process, manage and archive the measurement data. An export function for transferring the measurement data e.g. to a laboratory information and management system (LIMS) is also part of FIAStudio. If possible, the analytical methods used are flow analysis procedures standardized in accordance with DIN EN ISO. The measurement ranges of the individual parameters are listed in the method list. The variance coefficient...

Medizin- und Labortechnik Engineering GmbH Dresden Cyanide analyzer The Cyanide analyzer consists of an autosampler and a FIA Nexus device with integrated digestion unit for the selective release of cyanide from metal complexes according to the flow injection method DIN EN ISO 14403-1 which describes the pyridine-free determination of free and total cyanide. Gas diffusion of the released cyanide in a membrane cell eliminates possible interferences caused by the sample matrix. As the membrane transfer is carried out with stationary acceptor solution, this leads to an enrichment of the analyte...
