Spring 2023 AUCTION!!! Closed (#520929)

The Q-Tof micro is a high resolution oa-TOF mass spectrometer that provides automated exact mass measurements in an easy-to-use benchtop instrument. It also features a quadrupole mass filter and collision cell for MS/MS analyses, making for a powerful combination that delivers simple exact mass measurement of fragment ions to yield increased confidence in structural elucidation and databank search results. The high-quality data delivered by the Q-Tof micro can provide information on elemental composition and structural characteristics, as well as excellent specificity for identifying your compounds in complex matrices. **Does not Include software. Key Features: Optional LockSpray and NanoLockSpray ZSpray sources for reliable exact mass measurement Data Directed Analysis (DDA) to detect of compounds of interest for automated switching from MS to MS/MS High resolution of 5,000 FWHM for resolving nominally isobaric ions Extended linear dynamic range for quantitative analysis oa-TOF analyzer with a wide acquisition range of up to 20,000 m/z Z-SPRAY ATMOSPHERIC PRESSURE IONIZATION SOURCE: The nebulized spray is orientated orthogonally and positioned off axis for maximum source longevity and analyzer protection against "dirty" samples, including Electrospray Probe allowing flow rate of 1-1000 ut/min directly into source. QUADRUPOLE ANALYSER: Precision engineered quadrupole analyzer mounted in a ceramic cradle. The standard mass range is 40 m/z to 4000 m/z resolving mode and 45 m/z to 20,000 m/z RF only mode. COLLISION CELL: High efficiency, 160mm hexapole collision cell. Collision energy is digitally controlled in the range 0 to +/- 200 V. Collision gas introduction and removal from the cell are also under software control. ORTHOGONAL ACCELERATION TIME OF FLIGHT ANALYZER: Precision engineered orthogonal acceleration time-of-flight mass spectrometer for MS and MS/MS data acquisition, comprising ion injection cell, high precision reflectron, chevron microchannel plate and time to digital convertor (TDC) ion counting system operating at up to 3.6 GHz.
