Used WATERS / MICROMASS TQD #293637094 for sale

WATERS / MICROMASS TQD (Tandem Quadrupole Detector) is a mass spectrometer designed for accurate and precise quantitative measurements of small molecules in complex matrices. This spectrometer uses three stages of orthogonally-aligned quadrupole lenses to separate ions of different masses. First, an atmospheric source samples the molecular ions created by an electron ionization source. These molecular ions are then introduced into the first quadrupole lens and separated according to their mass-to-charge ratio. The lens is then scanned from low to high mass in order to achieve the desired resolution. The scanned ion beam is then passed onto a second quadrupole lens, in which the parent ions are fragmented into smaller daughter ions.This daughter ion beam is then scanned by the third and final quadrupole lens which separates the different fragments according to mass. WATERS TQD spectrometer then measures the abundances of the daughter ions which results in a parent ion spectra. This parent ion spectra can then be used to assess the chemical composition of the sample, analyze mixtures, and also accurately quantify small molecules. This spectrometer is often used in the food, pharmaceutical and environmental industries as a powerful tool for analyzing complex mixtures. MICROMASS TQD spectrometer has high reproducibility and maintainability with its high resolution and accuracy. Additionally, it reduces the need for manual adjustment and reduces the possibility for error. This instrument has the ability to measure a wide range of molecular masses with high sensitivity and detect ions at low concentrations, making it suitable for both qualitative and quantitative measurements. Additionally, TQD is considerably robust and can be used with a variety of sample matrixes making it a reliable instrument in the field of small-molecule analysis.
