Used THERMO QUEST Trace GC #9129566 for sale

THERMO QUEST Trace GC is an advanced gas chromatography instrument that combines the robustness of the industry-leading GC portfolios with the power and functionality of a full-featured mass spectrometer. This system is designed to support a range of challenging GC-MS applications from single-component to complex multi-dimensional separations. Trace GC offers a host of key features and benefits, including automated one-step method development, accurate mass measurement and confirmation, and exceptional scan speed and sensitivity. It comprises of three subsystems: the gas chromatograph, the autoinjector, and the vacuum mass spectrometer (MS). Together, they form a highly efficient analytical system. The gas chromatograph consists of two major components, the oven and the column. The oven contains many temperature-controlled modules, which help to accurately separate chemical components from the sample and ultimately provide the data. The column is typically a stainless steel tube containing a tightly packed porous material. As the sample enters the oven, it enters the packed bed material and is then carried out through the tube and into the MS. The autoinjector offers low-volume injection, accurate and repeatable delivery of sample, and eliminates potentially toxic manual sample handling. It operates by sending a heated geometrically defined syringe into the sample source, which is then automatically withdrawn. The mass spectrometer consists of the ion source, the ion detector and the ion analyzer. The ion source rapidly converts the sample into gas phase ions for measurement and analysis. The ion detector is a highly sensitive device that measures the electrical current generated by the ions and transmits the information to the analyzer. The analyzer then interprets the information and displays the result in graphical or numerical form. Lastly, THERMO QUEST Trace GC operates on a computerized data acquisition and control system that enables high-speed, easy-to-use operation and flexibility, enabling it to handle complex separations and analyze multiple samples with diminishing effort and in remarkably short periods of time. In short, Trace GC is a leading-edge gas chromatography technology that offers superior performance and flexibility in applications from single-component to complex multi-dimensional separations.
