Section II: Object
Purchase of a LC-MS (Q Exactive).
The Department of Environmental Science (ENVS) is going to buy a new liquid
chromatograph-mass spectrometer (LC-MS) to be used for determination of organic
compounds in different environmental matrices (water, soil and biota).
The instrument will be used for non-target analysis of organic compounds in
environmental samples (screening for unknown compounds) and for target
quantitative analysis. Environmental matrices are generally quite complex and
organic compounds are often present at very low concentrations. Thus, an instrument
used for these analyses must be capable of providing high sensitivity
and, at the same time, high mass accuracy in order to identify the organic compounds
with a high degree of confidence. High mass accuracy and high sensitivity
are also necessary for quantitative target analysis of compounds that are not
amenable with normal LC-MS because of e.g. interferences from similar groups
of chemicals.
The Q Exactive (Thermo Scientific) is equipped with Orbitrap technology (patented
by Thermo Scientific) that has a resolution capability of 140 000 (= high
mass accuracy) and sensitivity in the low femtograms of analyte injected on column.
The sensitivity of the Q Exactive is generally much higher than that of a QTOF.
On the other hand, at very low concentrations, the mass resolution of the
Q-TOF is not as good as the resolution at high concentrations, while the Q Exactive
maintains the high mass resolution even at very low concentrations. Since
many of our projects involve environmental samples (water, soil and biota)
where organic compounds are often present at trace levels, high mass resolution
is mandatory at low concentrations.
Thus, only the technical characteristics of the Q Exactive can satisfy our need of
high sensitivity and high resolution at the same time.
