Small Molecule Analysis

GC Sample Tray

Our lab is equipped with a range of instruments suitable for the analysis of small moelcules. We are open to collaboration with other groups wanting to analyze metabolites. If you are interested in exploring small molecule analysis with our lab group, contact Dr. Mark Bernards directly.

Our instruments include:

Agilent 1260LC with 6230 TOF MS

Agilent 1260 U-HPLC with 6230 Time-of-Flight (TOF) Mass Spectrometer

The Agilent 6230 TOF is an accurate mass time-of flight mass spectrometer suitable for the measurement of molecules in the 100-3200 m/z range. It was acquired using funds from the NSERC RTI program. The 1260 LC can be operated as a stand alone instrument or used with the TOF-MS. We currently use the 6230 for routine analaysis of plant hormones and ginsenosides. The instrument is equipped with separate ESI and an APCI sources. A small fee per sample is charged for analysis with the LC-TOF-MS.

Varian 3800 GC with 220 Ion Trap MS

Varian 3800 Gas Chromatograph with 220 Ion Trap Mass Spectrometer

The Varian GC-IonTrap MS is a robust workhorse gas chromatography system. We use it for routine analysis of fatty acid methyl esters (FAMEs) and other suberin-derived fatty acyl  compounds. The instrument can be set up for the analysis of range of volatile compounds and is equipped with two injectors for simultaneous sample analysis by FID and MS.

Agilent 7890 GC

Agilent 7890 Gas Chromatograph with FID

The Agilent 7890 GC is a stand-alone GC with FID. The instrument is fitted with a Combi-PAL robotic autosampler and can be configured for a wide range of small molecule analyses. The system is used for routine anlysis of insect pheromones (acetylated 1-alkenols), monosaccharides (as acetylated sugar alcohols) and FAMES.
