Two Liquid Chromatographs (Agilent HPLC 1200 series) coupled to a Tandem Mass Spectrometer (Agilent 6410B LC MS/MS) and to an Ion Trap (Agilent 1300 LC Msn) are new in the ASET lab through an NSF MRI grant from the chemistry division. The LC MS/MS is used to quantify a wide variety of organic compounds including pharmaceuticals, chlorinated pesticides, herbicides, phthalate, and perchlorate. The Instrument is suitable for ultra low level quantification where compounds are recorded by their initial mass and the mass of a typical fragment of the molecule produced in the collision cell. It consists of two quadrupole units and a collision cell. The IonTrap with its n-time fragmentation capability is used to identify compounds such as phospholipids and proteins through the fragmentation pattern of these molecules. Both Instruments are used in faculty, graduate and undergraduate research across the UA system and in teaching classes.
Agilent LC MS/MS system is new in the ASET lab. It will be used for a wide variety of compounds including drugs, hormones, perchlorate, natural organic substances, and persistant organic pollutants. The Instrument is suitable for ultra low level quantification. It consists of two quadrupole units and a collision cell. Analytes are recorded by their initial mass and the mass of a typical fragment of the molecule produced in the collision cell. Two Varian GC-MS/MS systems that allow qualitative and quantitative analysis of volatile or extractable organic compounds up to a molecular weight of about 400 amu. Compounds extracted or purged from samples such as water, soil, and tissues will be analyzed by these fully automated instruments. Presently these instruments are being used for analysis of disinfection byproducts (e.g. total trihalomethanes and haloacetic acids) in treated water, persistent organic pollutants, and fatty acids present in animal tissue, organs, and human plasma. One GC can be connected to an electron capture (ECD) detector for sensitive measurement of halogenated compounds (e.g. PCBs). Dionex Accelerated Solvent Extraction (ASE) system that enhances sample preparation. This automated system provides faster extractions of both major constituents and trace contaminates found in tissue and soil samples. Typical methods run on the ASE require 10 times less solvent than classical methods and can be completed much more quickly. © 2008 ASET Laboratory |
