Shimadzu's GCMS-QP5050A benchtop quadrupole mass spectrometer features an extended mass range to 900 Daltons and optional positive and negative chemical ionization (PCI and NCI). This wide variety of ionization modes and ability to analyze high molecular weight compounds makes the GCMS-QP5050A the answer to your application requirements.
Extraordinary Sensitivity The GCMS-QP5050A can detect 100 pg of methylstearate at S/N better than 60 in scan mode (SIM mode is even more sensitive). Scan speeds of up to 6,750 AMU/sec. are achieved with unit mass resolution. The MS is paired with our GC-17A gas chromatograph, which uses Advanced Flow Control (AFC) for rapid, reproducible results.
Minimal Downtime All ion source parts can be accessed from the front of the instrument for easy maintenance. The efficient 150 L/sec turbomolecular pump and rotary pump quickly achieve a high vacuum in less than 5 minutes!
Support for a Wide Variety of Applications The GCMS-QP5050A's exceptional performance can be expanded with a wide variety of accessories, including the DI-50 direct insertion probe in all ionization modes and the PYR-4A pyrolizer |
