• LEAP HDX automation
  The LEAP HDX platform is an advanced, automated scheduling and experimental workstation providing ease of use, high reproducibility and exceptional data quality for HDX experiments.

  Labeling
  HDX relies on accurate timing of the labeling step.

  Quenching
  The system will optimize the timing of the labeling step to ensure quenching is just in time for the LC-MS injection, using a chilled syringe. A typical experiment might consist of a dozen time points, in triplicate, for each protein sample. The LEAP HDX system will schedule the experiments and perform all steps for each time point of every sample. Long labeling experiments are automatically scheduled first to ensure the shortest possible instrument time.

  Optimized HDX fluidics
  The introduction of optimized HDX fluidics that enables full fluidic path backflushing, extending column life and maintaining consistent retention times to deliver higher quality data.

  The new fluidics pathway is built upon UHPLC rated valves and column hardware (21 kpsi), with flow paths minimized to reduce swept volumes.

  Trajan manufactured HDX specific pre-cut, high pressure lines and fittings, designed to improve reliability and enhance performance. All fluidic components are designed to offer consistently reproducible results.

• ChronosHDX control software
  Meeting the challenge of producing the highest quality data sets.

  HDX experiments require time-sensitive operation. Therefore, in traditional methods, an operator has to attend throughout the course of HDX experiments. However, time-controlled automation enables unattended operation using intelligent scheduling with Chronos software.

  Trajan uses ChronosHDX scheduling software to automate the precise labeling and quenching of samples, as well as injection and digestion of proteins on the LC-MS analysis system.

  • Precise on-exchange data point timing
  • Reproducible experimental conditions
  • Multi-valve control for trapping and elution of digested peptides to the LCMS system
  • Throughput optimization with elimination of timing conflicts
  • Simple graphic user interface
  • Advanced method editing capabilities
  • Integrated with HDExaminer data processing software from Sierra Analytics

  

  HDExaminer
  Native data format compatibility with HDExaminer increases high confidence data and allows you to get to results faster.

  • HDExaminer finds accurate results even with overlapping peptides.
  • The software works well with low resolution or high resolution data.
  • Imports MS data from Agilent, AB Sciex, Bruker, Thermo, or Waters instruments, as well as mzXML or mxData.
  • Imports peptide search data from SEQUEST HTML, Mascot XML, Proteome Discover xls or pepXML.

  Efficient system control and optimized experimental design
  Our Chronos for HDX software now offers a streamlined interface for HDX users and automatically overlaps time points for maximum MS efficiency.

  Temperature control at all steps ensures reliable data. Sustained 0°C environment reduces back exchange, improves sample stability and overall reproducibility.

  Our most flexible automation platform yet offers the ability to run multiple experimental methods in the same sequence. Native data format compatibility with HDExaminer increases high confidence data and allows you to get to results faster.
