  • Easily switch between EI and PCI methods using new Smart-CI source
  • High-speed scan and data acquisition using Advance Scanning Speed Protocol (AASPTM) to achieve speeds up to 20,000 µ/second across all masses
  • Ecology mode reduces costs associated with power and carrier gas consumption
  • Smart productivity features like:
    • Active-Time Management that accurately determines operation times
    • Simplified injection port maintenance with new Click-Tek injection port top.
    • Twin-line MS kit eliminates the need to swap columns by installing two columns into the MS at one time.

Inert Flow Path of GC/MS Achieves High-Sensitivity

GCMS-QP2020NX Single Quadrupole GCMS Inert Flow Path

Minimizing adsorption and other losses in the flow path from sample injection to the detector is important for stable, high-sensitivity measurements using GC/MS. The flow lines in the GCMS-QP series and the GCMS-TQ series consist of high-quality, highly reliable consumable parts, so even trace concentrations of components can be detected with high sensitivity and favorable repeatability.

Utilizing patented Advanced Scanning Speed Protocol (AASPTM) technology allows high-speed scanning at 20,000 u/second without sensitivity loss or spectral distortion. This is effective for scan data sensitivity improvements and favorable mass spectrum acquisition, particularly in high-speed analysis with Fast-GC/MS, simultaneous Scan/SIM, FASST analysis, and applications using Comprehensive GC/MS (GC x GC/MS).

The precision-designed quadrupole mass filter is able to obtain accurate mass assignments across the entire mass range, and is equipped with a pre-filter to reduce the influence of contamination on the main filter.
