Automated Titrators

The TitroLine titrator series can be used for advanced titration and dosing applications. This series completes SI Analytics' offering of automatic titrators and includes the TitroLine 6000, TitroLine 7000, and TITRONIC 500 piston burette. The family of instruments combines accuracy and ease-of-use to create solutions that offer unmatched flexibility and reliability for content analysis in various samples. The SI Analytics TitroLine titrators offer a wide spectrum of capabilities for a variety of applications across the water and wastewater, environmental, food and beverage, pharmaceutical, and chemical industries. Compact in design, the TitroLine 6000 and TitroLine 7000 titrators feature a new PC-based user interface, offering unparalleled ease-of-use and eliminating the need for extensive training. High throughput is also ensured as a result of the instruments' ability to automatically recognize both the dispensing module and reagent data, optimizing productivity. In addition, the easy-to-read display tracks titration curve and data.

Quadrupole-Orbitrap Mass Spectrometer

The Q Exactive high-performance benchtop quadrupole-Orbitrap LC-MS/MS is the first commercially available instrument to bring together quadrupole precursor selection and high-resolution accurate mass (HR/AM) Orbitrap mass analysis to deliver high-confidence quantitative and qualitative workflows. With innovative HR/AM Quanfirmation capability, the Q Exactive mass spectrometer makes it possible to identify, quantify and confirm more trace-level metabolites, contaminants, peptides, and proteins in complex mixtures in one analytical run. Unlike other technologies, high-confidence results are obtained without sacrificing MS/MS sensitivity, mass resolution, or quantitative reproducibility. Powered by Orbitrap technology, the Q Exactive system delivers ultrahigh resolution and exceptional mass accuracy, enabling high-confidence identifications and retrospective data analysis. Fast scanning and spectral multiplexing ensure the system is fully compatible with UHPLC separations. Fast positive-negative scan-to-scan polarity switching enables detection of a wide range of compound types in a single analysis.

Contaminant Quantitation

The DART XZ Transmission Module is designed for rapid identification and quantitation of components present in food products, dietary supplements, and chemicals. Available as a new Experiment Module for use with the DART-SVP open-air ionization source, the XZ Transmission Module enables analysis in seconds per sample. When combined with the latest generation of mass spectrometers from Thermo, Agilent, Waters, Bruker, and AB SCIEX, the system quickly identifies contaminants or economic adulterants, providing a critical tool for nontargeted screening. In operation, liquid samples or extracts are pipetted onto 96 discrete positions of the XZ Transmission Module consumable screen by using either manual pipetting or laboratory robotics, thus allowing integration of the device into the laboratory workflow and informatics. Automated analyses of the samples is completed by moving the screen into position between the front of the DART source and the inlet of the mass spectrometer under control of the SVP software.

ICP-OE Spectrometers

The Optima 8x00 series of inductively coupled plasma optical emission spectrometers (ICP-OES) offers improved performance and reduced operating costs for analysis of environmental, food, pharmaceutical, product safety, and geochemical samples. ICP-OES is a highly sensitive, rapid technique for determining the elemental composition of a wide variety of sample types. The Optima 8x00 series is designed for ease of use and exceptional throughput and detection limits, which helps maximize productivity and profitability of testing laboratories. The Optima 8x00 series has a number of new features that will enable laboratories to lower their cost per analysis and more easily meet the ever-changing regulatory requirements. New innovative radio frequency generator technology dramatically reduces argon consumption, thus driving a reduction in the cost of ownership with increased efficiency. A novel electronic sample introduction system provides superior sensitivity, which, coupled with enhanced stability, helps address the ever-increasing regulatory demands of the environmental and pharmaceutical markets.

PCR Assays

Eleven new mericon kits are offered for convenient, fast, and reliable food testing. The complete mericon portfolio encompasses products for the detection of a broad range of genetically modified organisms (GMOs), pathogens, and ingredients from animals or plants. The new, ready-to-use real-time polymerase chain reaction assays include GMO kits for the quantification of MON810 and RoundUp Ready Soy, as well as the detection of the 35S-pat and CTP2-CP4EPSPS constructs. Additionally, other new kits are designed for the identification of ingredients from cattle, chicken, turkey, corn, and apricot kernels. Qiagen's food testing offering now comprises 27 PCR assays and covers the complete workflow from dedicated sample preparation solutions for a variety of sample types through to analysis and detection.
