Metabolite Profiling Facility
The Metabolite Profiling Facility (MPF) provides state-of-the-art technologies that enable both qualitative (defining all components of a metabolome) and quantitative (determining differential concentrations of metabolites) metabolomics in complex biological systems. This facility employs highly sensitive mass spectrometry coupled with liquid chromatography and multi-dimensional gas chromatography for precise sample analysis. Metabolite profiling is an integral component of systems biology, an exciting field that combines genomics, transcriptomics and proteomics to define cellular functionality. Our elite scientists will empower researchers with new technologies, methods development, expert training and consultation.
Waters Micromass LCT Premier (TOF), coupled to HPLC. The instrument is an easy to use benchtop mass spectrometer that utilizes a high-resolution time-of-flight (TOF) analyzer to enable automated exact mass measurements. The TOF analyzer utilizes W-Optics, a novel method for enhancing resolution that provides up to 10,000 FWMH resolution. The use of in-source collision induced dissociation (CID) can also yield structural information. This system is coupled with a Waters CapLS System cap/nano 1-D HPLC system capable of microliter and nanoliter flow rates.Similarly, the MS is equipped with regular and nano electrospray ionization sources.
Waters Micromass Q-Tof micro, coupled to HPLC. The instrument is a high resolution time-of-flight (TOF) mass spectrometer that enables automated exact mass measurements. The instrument features a quadrupole mass filter and collision cell prior to the TOF for MS/MS analyses. This powerful combination delivers exact mass measurement of fragment ions to yield increased confidence in structural elucidation and database searching. This instrument is coupled with a Waters 2795 Alliance HPLC system, with autosampler and photodiode array (PDA) detector. The MS is equipped with electrospray and APCI ionization sources.
Agilent MSD/TOF, coupled to HPLC. The instrument utilizes an innovative analog-to-digital (ADC) acquisition system that offers high resolution mass accuracy over a wide dynamic range. The automated calibrant delivery system and dual-nebulizer electrospray ion source of the LC/MSD TOF can continuously introduce reference mass compounds at very low levels. This results in outstanding mass accuracy, typically less than 3 ppm. This instrument is coupled with an Agilent 1100HPLC system, with autosampler and photodiode array (PDA) detector. Two such instruments are available to the MPF.
LECO Pegasus 4D GCxGC-TOF. This instrument can be operated as either a GC/MS or a GCxGC/MS. When used in GCxGC mode, it is possible to separate and detection hundreds-to-thousands of compounds in a single sample. This would not be possible by conventional GC/MS. Separations, which previously resulted in dozens or hundreds of peaks, now yield thousands of individual components from complex mixtures. The powerful, easy-to-use ChromaTOF® software simplifies component identification by employing integrated NIST database searches. Other unique processing capabilities (such as sample comparisons) allow for automated mining of complex GCxGC data sets to extract previously unidentifiable similarities and differences. Ionization is performed using electron impact (EI). The upper mass limit for this instrument is 1,000 daltons. Different derivitization schemes are routinely employed to asssit in sample volatility. Two such instruments are available to the MPF.
The Agilent 6460 triple quadrupole mass spectrometer coupled with the Agilent 1200 Rapid Resolution HPLC provides highest sensitivity for small molecule profiling and MS/MS level analyses. This instrument provides extremely high sensitivity and throughput for small molecule analysis. Two such instruments are available.
The Thermo-Finnigan Orbitrap hybrid quadrupole ion trap mass spectrometer coupled with the Agilent 1100 HPLC system with autosampler provides a sub-dalton resolution trap instrument for small molecule detection and quantification.
