About 20% of the GC-MS
market belongs to ion trap 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.
Wash conditions were optimized to remove polar cationic contaminants that interfered with the GC-MS
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
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 gas chromatographic separation method (GC-MS
) was carried out in one stage by injecting the sample without any prior procedure.
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
Thermo Scientific Orbitrap GC-MS
systems have been updated with new capabilities in high resolution accurate mass (HRAM) GC-MS
, designed to provide users across metabolomics, food safety, environmental, pharma and toxicology applications with data accuracy.
