CAFT's Instrumentation Facility is well equipped with the most sophisticated research grade instruments. For maximum productivity and performance we have adopted a policy of dedicating instruments to specific analytical tasks. Each instrument is set up and optimized for particular operational modes eliminating the need for time consuming changeovers. Tasks are carried out on the instrument using the technique which is most suitable. The following is a description of the instruments and techniques:
| Finnigan MAT 8230 High Resolution Gas Chromatograph - Mass Spectrometer equipped with a Varian 3400 gas chromatograph. This instrument has electron and chemical ionization capabilities with both positive and negative chemical ionization modes. The instrument is equipped with many specialized accessories including thermal desorption apparatus designed and patented by Dr. Thomas Hartman of our facility, which allows for the determination of volatile as well as semi-volatile components in foods. In addition, the 8230 is a high resolution instrument capable of accurately measuring masses to four decimal places, allowing determination of elemental composition. |

Finnigan MAT 95 S High Resolution Gas Chromatograph-Mass Spectrometer equipped with a Varian 3400 gas chromatograph. This instrument also has electron ionization and chemical ionization capabilities with both positive and negative ion modes and is a magnetic sector research grade high resolution instrument with high accuracy and sensitivity. It has all and in many cases exceeds the capabilities of the other equipment. It is fully computer controlled for the acquisition and processing of data.
Finnigan TSQ-7000 Research Grade Triple Quadrupole Gas Chromatograph Mass Spectrometer This research-grade tandem GC-MS-MS instrument is equipped with a standard EI/CI source, Direct Introduction Probe and is capable of positive and negative ion operation.
Specialized Equipment an Accessories for Sample Preparation & Analyses. Accessories available on all GC and GC-MS equipment include specialized Direct Insertion Probes, Gas Loop Injectors, Headspace Analyzers, Thermal Desorption and Pyrolysis sample introduction devices. The laboratory also maintains a suite of custom sample preparation equipment including extraction cells for migration studies, combustion chambers, Purge & Trap sampling chambers and many types of custom glassware apparatus for sample extractions and processing.
Waters Micromass Platform II High Performance Liquid Chromatograph - Mass Spectrometer. The mass spectrometer is equipped with an Atmospheric Pressure Chemical Ionization (APCI) ion source as well as with an Electrospray Ionization (ESI) ion source. Both positive and negative modes can be obtained on the instrument.
The unit is interfaced to a Varian 9012 ternary HPLC pump and the effluent routed through a Varian 9050 variable wavelength UV/VIS detector. This unit also has a Varian autosampler for automatic sample injection.
Waters Micromass Quattro HPLC-MS-MS with a Shimadzu gradient HPLC.
This triple quadrupole mass spectrometer is equipped with Atmospheric Pressure Chemical Ionization (APCI) and Electrospray Ionization (ESI). It is one of the most sensitive instruments for low level quantity of organics in complex matrices. This instrument is interfaced to a Shimadzu gradient HPLC including a LC-10A system controller, two LC-10AD pumps, a SPD-10A UV detector and a LC-10A autosampler.
GC units: Six off-line Varian 3400 gas chromatographs with various detectors including FID, ECD, NPD and FPD. A GC with an olfactory port (Sniff Port) is also available for GCO technique (peak sniffing) and/or for GC-Prep (GC Peak Isolation)
HPLC Units: Six or more available, which include: ESA (Shimadzu) Coularray HPLC with diode array detection, electrochemical, fluorescence and refractive index
