Used THERMO FISHER SCIENTIFIC TSQ Quantiva #293597595 for sale

THERMO FISHER SCIENTIFIC TSQ Quantiva is an advanced triple-quadrupole mass spectrometer (MS) equipment designed to enable highly sensitive and specific quantification of proteins and peptides from biological samples. The system combines a vacuum-tight vacuum unit, a quadrupole analyzer, and an electrospray ionization (ESI) source for maximum efficiency. The patented ion optics of the machine allow for superior quantitative analysis, offering unprecedented levels of sensitivity for quantitative assay development. The triple-quadrupole analyzer consists of three quadrupoles arranged in sequentially-pulsed operation. The first two quadrupoles act as ion filters, selecting ions of a specific mass-to-charge ratio. The third quadrupole further refines the mass selection and also drives fragmentation processes, allowing user selection of precursor/product ion pairs. Mass resolution obtained with TSQ Quantiva is superior to other ion-trap instruments, even when using low spray currents. The instrument can be operated in multiple scan modes, including selected ion monitoring, single reaction monitoring (SRM), precursor ion scanning, neutral loss scanning, or multiple reaction monitoring (MRM). Additionally, multiple scan windows can be used to optimize quantification. The source of THERMO FISHER SCIENTIFIC TSQ Quantiva is a patented atmospheric pressure ionization source, capable of both positive and negative ionization. This source offers superior ion transmission, sensitivity and dynamic range. The source also offers several modes of operation, including ESI, atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) modes. The source is highly stable and offers excellent quantitative performance, even in small volumes. TSQ Quantiva is an outstanding choice for both laboratory and production use. It is easy to programme and maintain, offering high levels of quality control and full integration with other THERMO FISHER SCIENTIFIC products for data handling, data analysis, and experimental operation. The tool offers superior sensitivity, linear dynamic range and selectivity, which makes it ideal for standard quantification workflows. THERMO FISHER SCIENTIFIC TSQ Quantiva is built and tested to strict standards and boasts of exceptional performance in sample analysis.
