Scion GC-TQ Premium Mass Spectrometer

Scion Product

Specification Sheet

The Scion GC-TQ Premium is the chromatographer’s choice for triple quadrupole mass detector; it is designed to match your most stringent needs for analytical performance and productivity.

The Scion GC-TQ Premium offers superior sensitivity and robustness based on the innovative ion optics, and fast and easy methods development for multicomponent quantitation following the unique Compound Based Scanning (CBS) approach with MRM library.

The Scion GC-TQ Premium GC-MS/MS system defines a new standard of usability for routine analysis and has the smallest bench footprint in the industry.

Performance Specification

*All tests use helium as carrier gas. EI MRM sensitivity test will be used as installation checkout specifications; not all other performance tests are confirmed at installation. † The Signal-to-Noise ratio S/N values are based on RMS

IDL**: Instrument Detection Limit, defined as IDL=t(0.99, f=7)×S, whereas t(0.99, f=7) is the one-sided student’s t-distribution value of 2.998 for 99% of confidence and for degree of freedom 7 (f=n-1, n the number of injections); S is the peak area standard deviation of 8 replicate injections. ‡ CI tests use methane as reagent gas
