Demand for lower detection limits of volatile organic
compounds in drinking water requires the use of a
mixed mode GC MS system The ability for
simultaneous full scan and selection ion monitoring
( is vital for low level quantitation The United
State Environmental Protection Agency (US EPA) 524 3
method details the analytical method for the
measurement of purgeable organic compounds in
water by capillary gas chromatography with mass
spectrometry
The SCION Single Quad ( mass spectrometer has a
unique feature, Compound Based Scanning ( for
easy automated setup and optimisation of complex
mixed mode methods CBS makes use of libraries that
store all the essential information about a compound
such as retention time, time window, qualifier and
quantifier ions Compounds are loaded directly into a
method, scan times are optimised with data acquisition
and processing tables synchronised Managing large
number of SIM acquisitions is made easy in mixed
mode
