Used THERMO SCIENTIFIC Q Exactive Plus #293603074 for sale

THERMO SCIENTIFIC Q Exactive Plus is a powerful, high performance LC-MS/MS spectrometer. It is designed to provide enhanced analytical capabilities, superior sensitivity and accuracy, and the flexibility to accommodate a wide range of sample types. The core of Q Exactive Plus is its high-resolution Orbitrap mass analyzer. This analyzer utilizes two stages of mass analysis to provide accurate mass determinations with an accuracy of up to 0.3 m/z. The first stage, multistage quadrupole mass filter, employs four mass filter rods to transfer ionized molecules through an electrostatic field and into the Orbitrap transimitter. The transimitter then directs the ions into an orbit-like path where they travel through an alternating electric and magnetic field before they enter the analytical chamber. The second stage, quadrupole linear ion traps, use a fixed potential to attract the ions and contain them in the analytical chamber so that they can be subjected to a time-varying electric and magnetic field for mass analysis. THERMO SCIENTIFIC Q Exactive Plus includes high-efficiency thermospray ionization (HE-TSI) technology, allowing for accurate and efficient sample ionization. This technology produces a narrow interface spray that is formed via a narrow aperture near the hot block and a helium heated nebulizer. The nebulized droplets are then directed toward an ion transfer tube where they pass through two orifice plates before entering the vacuum of the atmospheric pressure ionization source. Q Exactive Plus is further equipped with a heated transfer line (HTL) that allows for direct injection of samples into the source chamber. This HTL is designed with a thermostatic heat shield on the source to ensure a low background noise. Additionally, THERMO SCIENTIFIC Q Exactive Plus comes with a vacuum nitrogen exhaust system which reduces pump noise so that all mechanical vibrations can remain undetected by the analyzer. Q Exactive Plus was designed to provide results of the highest accuracy and sensitivity for all sample types. Through its innovative technology and features, such as its high-resolution Orbitrap mass analyzer, high-efficiency thermospray ionization, heated transfer line, and vacuum nitrogen exhaust system, THERMO SCIENTIFIC Q Exactive Plus will ensure your analysis is conducted with the utmost precision and accuracy.
