Agilent 7200 QTOF GC-MS with 7693 Autosampler

When you're running unknown identification or need to confirm molecular formulas without reference standards, single-digit ppm mass accuracy changes everything. The Agilent 7200 QTOF GC-MS with 7693 Autosampler gives you resolution above 40,000 FWHM with scan speeds fast enough to capture narrow peaks from modern fast GC methods, which means you're not choosing between throughput and data quality.

Accurate Mass Detection with Quadrupole Time-of-Flight GC-MS Technology

Mass Range: Up to 20,000 m/z
Resolution: Greater than 40,000 FWHM
Scan Rate: Up to 50 spectra/second
Ionization Modes: EI, CI, and PCI/NCI
Autosampler Capacity: Up to 150 vials
Temperature Range: Ambient to 400°C
Carrier Gas: Helium or Hydrogen
Vacuum System: Oil-free scroll pump

Traditional quadrupole systems give you nominal mass, which works fine when you know what you're looking for. QTOF technology measures exact mass to four decimal places, letting you calculate elemental composition directly from the data. That 2-3 ppm mass accuracy means the difference between C₁₂H₁₀O and C₁₃H₁₄ is clear, not ambiguous.

The oil-free vacuum system matters more than most people realize. Oil pumps create hydrocarbon background that interferes with volatile organic analysis, especially below 100 m/z. You're also avoiding quarterly oil changes and the risk of backstreaming contamination that ruins weeks of work.

High-Throughput Analysis Using 7693 Autosampler Integration

• 150-vial capacity handles overnight batch runs without operator intervention
• Programmable injection parameters adapt to different sample viscosities and concentrations
• Heated zones throughout prevent thermal degradation of sensitive compounds
• Precise syringe control reduces carryover below detection limits between injections
• Automated calibration sequences eliminate manual injection variability that skews curves

Manual injection introduces operator-dependent variation that regulatory methods won't tolerate. When you're validating EPA 8270 or running pharmaceutical impurity profiles, the reproducibility from automated sampling is non-negotiable. Injection-to-injection precision typically stays within 1-2% RSD, which is what you need for quantitative work.

Compound Identification Through QTOF Mass Accuracy

Full-scan acquisition at 50 spectra/second keeps up with 1-2 second peak widths from fast chromatography. You're capturing 50-100 data points across each peak, which gives you the spectral quality needed for library searching and accurate mass confirmation simultaneously.

Sub-picogram detection limits in full-scan mode mean you're not sacrificing sensitivity for the comprehensive data. Traditional systems force you into selected ion monitoring for trace work, but you're blind to everything except your target list. QTOF collects everything, so when an unexpected contaminant shows up six months later, you can retrospectively analyze your archived data files without re-running samples.

The wide dynamic range handles trace components alongside major peaks in the same injection. You'll detect 10 ppb pesticide residues while simultaneously seeing percent-level matrix components without detector saturation. That matters when you're analyzing environmental extracts or food samples with complex backgrounds.

Automated Workflow for Multi-Sample Batches

Labs running synthesis verification benefit directly from accurate mass confirmation. When you're checking reaction products from Glass Jacketed Reactor (Double Glass Reactor) TOPT-10L, Glass Jacketed Reactor (Double Glass Reactor) TOPT-20L, or Glass Jacketed Reactor (Double Glass Reactor) TOPT-50L systems, the molecular formula determination confirms your target product and identifies side reactions or impurities without needing to synthesize reference standards.

Scale-up work from Glass Jacketed Reactor with Lid Lift and Body Rotation Function TOPR-30L or Glass Jacketed Reactor with cover lift and body turn function TOPR-20L requires analytical certainty before committing to production batches. Accurate mass data catches structural isomers and unexpected rearrangements that nominal mass systems miss entirely.

The three turbomolecular pump vacuum system maintains stable conditions across temperature-programmed runs. You're getting consistent mass accuracy whether you're analyzing volatiles at 50°C or semi-volatiles ramping to 350°C. Independently heated ion source prevents cold spots that cause peak tailing or sample decomposition.
