GC/MS with Headspace for Terpene Analysis

GC/MS with Headspace for Terpene Analysis

Analyze 22 terpenes common to marijuana in under 6 minutes using the Agilent 7697A/7890B/5977B headspace-gas chromatography-mass selective detection.

Agilent 5977 Mass Spectrometer Features:

Extractor Ion Source - The 'push-pull' principle of the Extractor Ion Source delivers more ions to the mass analyzer and increases the confidence of your trace analysis methods. Triple-Axis Detector (TAD) - Optimizes signal-to-noise by combining efficient ion collection and amplification with the elimination of neutral noise. 

• EI source: Standard, Inert or high sensitivity Extractor
• CI source: PCI, NCI, and EI acquisition (Optional)
• Ion source temperature: 150–350 ℃
• Quadrupole temperature: 106–200 ℃
• Mass filter: Monolithic hyperbolic quadrupole
• Mass range: 1.6–1,050µ
• Mass axis stability: Better than 0.10 u/48 h
• Detector: Triple-Axis Detector with long life EM

Agilent 7890 Gas Chromatograph Features:

The combination of precise pneumatic and temperature control leads to extremely precise retention time reproducibility, which is the basis for all chromatographic measurement.

• Oven temperature: Ambient +4 – 450 ℃ Ambient +5 – 350 ℃
• Oven ramps/plateaus: Supports 20 oven ramps with 21 plateaus. Negative ramps are allowed.
• Retention-time locking: RTL-ready

Agilent 7697 Features:

• Standard 11 sample position with 3 priority samples
• Exchangeable trays during a sequence for increased sample capacity
• Hydrogen carrier and auto Sleep/Wake modes conserve valuable laboratory resources
• Sample Bar Code Reader with data transfer capabilities allows you to track samples before they enter the oven
• Multiple headspace concentrations (MHC) with up to 100 extractions per GC start allows for more complete sampling and increased sensitivity
• Multiple headspace extractions (MHE) with up to 100 extractions per vial
• Supports 10 mL, 20 mL, or 22 mL vials without an adapter
• Samples depressurize before returning to the tray
