About 20% of the
GC-MS market belongs to ion trap
GC-MS.
The
GC-MS analyses were performed using a Shimadzu QP-1100EX instrument.
Samples were analyzed by
GC-MS with LOQs of 2.5 [micro]g/L for codeine, norcodeine, morphine, and normorphine (48, 49).
One strategic approach to this market is the low-cost
GC-MS, systems priced under $45,000.
We measured nitrate in 24 urine samples from patients suffering from various diseases by the present HPLC method and by a previously described
GC-MS method (4).
For some immunoassays, the agreement with ID/
GC-MS was not so good, as shown by the line of best fit for these assays (Fig.
Alongside the collection of
GC-MS solutions, Thermo Fisher is hosting a seminar series with company and industry experts.
The area under the
GC-MS peaks points out not only the concentration but also the intensity of mass spectral fragmentation of detected compounds.
The components of each fraction were identified by gas chromatography-mass spectrometry (
GC-MS).
