The complete package includes the Peak 1024 nitrogen generator, the vacuum pump and the housing, as well as a PC with MultiQuant and Analyst software. The SCIEX Triple Quad 3500 LC-MS/MS system combines the ease of liquid chromatography, suitable for a wide range of analytes, with the quantitative power of triple quadrupole tandem mass spectrometry. Liquid chromatography is suitable for analyzing a wide range of analytes. In fact, many compounds that are difficult to analyze by GC, such as thermolabile and chemically unstable analytes, amines, and semi-volatile compounds, are ideal candidates for LC-MS/MS. GC-based analyses, including GC-FID and GCMS, typically require samples to be in an organic injection solvent. This often requires derivatization of hydrophilic analytes to improve their volatility, ionization or peak shape. Although typically simpler, HPLC-UV and HPLC-DAD assays can also involve complicated sample preparation techniques and, depending on the class of materials, can be labor intensive. In contrast, although LC-MS/MS sample preparation methods can include solid-phase extraction or liquid-liquid extraction, they are often as simple as direct injection, dilution, or protein precipitation. By reducing sample handling and reducing the number of steps in sample preparation, not only are sources of contamination minimized, but time is also saved. And with today's ultra-high performance liquid chromatography (UHPLC) systems, you can save even more time with ultra-fast chromatographic separations. The sensitivity of LC-MS is undeniable. But you also need the flexibility to handle an ever-changing range of applications. The ExionLC system gives you more power, more flexibility and more options than a simple HPLC. With the ExionLC you can build on its modular design to expand your laboratory's range of applications and analysis. Important features of the system are:. Modular design for flexible applications. Tray cooling preserves sample integrity. A forced air column oven for stable retention times. A large solvent tray for unattended operation. Optionally available accessories for expansion as needed. The ExionLC frontend includes:. Solvent tray. Degasser. Control unit. 2x AC pump. AC column oven. AC Autosampler Labprocure is responsible for this device.
