Used APPLIED BIOSYSTEMS Voyager DE STR #87888 for sale

APPLIED BIOSYSTEMS Voyager DE STR is a state-of-the-art mass spectrometer that operates in the matrix-assisted laser desorption/ionization (MALDI) ionization source mode. The spectrometer is designed to analyze complex samples with high resolution and sensitivity. It is an ideal instrument for analyzing peptides, oligonucleotides, and large biomolecules such as proteins, carbohydrates, and lipids. The instrument utilizes a high vacuum quadrupole mass filter to isolate and analyze both positive and negative ions. It uses a pulsed ultraviolet (UV) laser, which is optically focused through an entrance slit into a sample plate, to desorb and ionize the sample molecules. The generated ions are then directed down an orthogonally arranged quadrupole, which selectively filters and transmits selected ions to the analyzer's detector. The spectrometer provides a range of features which allows the user to customize the performance and is equipped with a range of different sources and detectors; thus, it can be tailored to address a wide range of applications. Specifically, the instrument allows the user to choose various source power levels, source spot size and position, source modulation time and mode, source mass filter size and mode, detector position and selectivity, and detector voltage, which can be easily adjusted to yield data with unprecedented resolution, mass accuracy and precision, and sensitivity. Voyager DE STR also offers advanced software capabilities, providing user-friendly data interpretation, as well as interactive graphics to visualize your data. The image analysis capabilities are highly adjustable and allow you to review your results in a straightforward manner. Additionally, the software can construct two-dimensional (2D) contour plots of sample profiles. Overall, APPLIED BIOSYSTEMS Voyager DE STR is uniquely qualified to address challenging applications in protein and peptide analysis, as well as small molecules and oligonucleotides. Its powerful capabilities provide precise and sensitive analysis of complex samples, and its cutting-edge software enables enhanced data interpretation.
