LC/MS performance and productivity through innovation. The Varian 500-MS LC ion trap instrument is the instrument of choice for high-throughput LC/MS analysis where sensitivity, reliability and productivity are essential. The Varian 500-MS is a new and innovative system that provides a robust platform for demanding LC/MS/MS applications. The system sensitivity, mass resolution and scan speed reflect the inherent advantages of the ion trap, while the new Enhanced Charge Capacity (ECC) expands the number of ions that can be stored. The result is higher sensitivity and reduced background noise for reliable quantification. With excellent sensitivity across the entire mass range in full scan mode and exceptional MS/MS and MSn capabilities, the Varian 500-MS quickly delivers superior qualitative information, even for the most complex sample matrices. Unique sensitivity enhancements include SelecTemp, the temperature-programmable API (atmospheric pressure ionization), for optimal analysis of thermally labile compounds. These innovations result in the remarkable performance and capabilities of the Varian 500-MS LC ion trap device. State-of-the-art API interface. The Varian 500-MS delivers increased sensitivity and selectivity for all analytes. Even highly thermolabile compounds can be reliably analyzed using Varian, Inc.'s patented, temperature-programmable SelecTemp API interface. Sample integrity is no longer a concern. SelecTemp enables optimal control of dry gas temperatures at any time during a complex analysis. Additional benefits of the SelecTemp API include reduced interface contamination, improved throughput, simplified setup and automatically recorded parameters for GLP purposes. The SelecTemp API's robust yet elegant design and its unique capabilities will reliably, consistently and easily improve the performance of routine, high sample throughput applications while increasing accuracy and productivity. ECC, triple resonance and the power of MSn. ECC ensures the reliable detection of trace amounts while maintaining high concentrations of co-eluting compounds and heavy matrices. Patented triple resonance scanning enables scanning speeds of up to 15,000 Da/second and preserves chromatographic spectral resolution. This fast scanning speed is complemented by rapid ion polarity switching of 200 milliseconds to provide optimal ion polarity detection for each analyte in the sample. Improved qualitative information is provided by the 500-MS with MSn operation up to n=10, expanding the spectral information content for structure elucidation. Unmatched ownership benefits. The versatility of the Varian 500-MS and its distinctive features allow it to be easily adapted to a wide range of analytical requirements. The 500-MS' standard electrospray ionization (ESI) source can be replaced with an optional atmospheric pressure ionization (APCI) source in less than a minute. LC flow rates from microliters to milliliters can be used with the fully adjustable electrospray ionization source and the vortex atmospheric pressure chemistry ionization source. The novel ion source design means the 500-MS requires less cleaning, resulting in increased uptime and productivity. The built-in syringe pump, diverter valve and electronic gas control (EGC) provide ease of use that further increases productivity. Clearly, the performance-focused Varian 500-MS delivers increased selectivity, sensitivity and accuracy while reducing contamination and downtime. The extensive capabilities of the Varian 500-MS ultimately translate into value through exceptional results, unparalleled economics and ownership cost advantages that are unparalleled.
