Product Detail

TQ GC-MS Mass Spectrometry (Gas Chromatography) Electron Ionization (EI) as standard ChroZen TQ GC/MS YOUNG IN Chromass Korea ChroZen TQ GC/MS is the right solution to achieve greater insight of the samples with the extremely selective and sensitive data for quantitative and qualitative information and will lead you to the whole new level from the method setup to the data elucidation and instrument maintenance. Its structural characteristics such as 180° curved collision cell and lens-free optics eliminate the interferences of co-eluting compounds and neutrons, minimize the need of maintenance and simplify the method setup to maximize the ease of use. Major Features of our ChroZen TQ GC/MS 1. 180° Curved Collision Cell The fast moving ions from the first quadrupole collide with the collision gas and they get dissociated while removing the interference of neutrons in the 180° curved RF-only quadrupole. This reduces the background noise and increases the signal-to-noise ratio, which means it efficiently improves MRM sensitivity in real sample matrice. 2. Active Focusing Ion Guide The 90° shaped ion guide curves the ions to eliminate neutrons and reduce noise. It’s also heated to 135℃ from the ion source for ions not to get condensed and contaminate the guide. There is a helium gas input to improve ion transmission so it provides a more focused ion stream that enhances the sensitivity. 3. Axial Ion Source The axial ion source generates ions on-axis from the column and its unique design including inert lenses reduces the contamination by sample matrice for higher sensitivity. It utilizes double filaments with electron-bouncing technology to increase productivity without the instrument downtime for the maintenance. 4. EDR (Extended Dynamic Range) Detection System Extended Dynamic Range (EDR) automatically adjusts the detector for the best signal-to-noise ratio (s/n) and EM voltage optimizes for every scan. 5. High Capacity of Turbo Pump The high capacity of dual stage (310 L/s and 400 L/s) turbomolecular pump rapidly stabilizes the vacuum status for higher productivity.
