In this study, we combined two fundamental and complementary techniques, gas chromatography coupled to time-of-flight-mass spectrometry (GC-TOF-MS) and ultra-performance liquid chromatography coupled to high resolution fourier transformation mass spectrometry (LC-FT-MS), to reach a higher coverage of the metabolome (Fig. 1).
Complementary nontargeted gas chromatography (GC /mass spectrometry (MS)–based assays provide more encompassing summaries by measuring features defined by mass spectra and retention time, with subsequent compound identification via comparison with a library of possible matches (5).
Environmental groups reacted with a mix of confusion and anger -- the pledge had been a hopeful sign for them amid a climate of increasing sales of S.U.V.'s and a complementary surge in gas consumption.
Complementary measurements of gas evolution and mass loss of the preceramic polymer during pyrolysis as well as changes in mass density and Young's modulus provide context for the physical changes revealed by XCT.
Liquid chromatography-mass spectrometry (LC-MS) and tandem LC-MS (LC-MS/MS) are increasingly used in toxicology laboratories as a complementary method to gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-ultraviolet detection (LC-UV) for comprehensive drug screening (CDS).
In fact, wind energy and natural gas are complementary, and offer a number of possibilities for coordinated use.
In addition, a high-performance complementary inverter and selective gas sensing based on MoS2 field-effect transistors was studied [6 8].
Electricity from coal is expected to comprise a smaller share of U.S. electricity supply in the coming decades as technological advances enhance the economic competiveness of wind and solar generators while natural gas, a complementary fuel for weather-dependent intermittent generation, remains inexpensive.
The in-depth analysis of genetic control of the CO2 fixation process in response to drought was possible after measuring different functional parameters using complementary techniques, such as gas exchange and chlorophyll fluorescence, that measure final carbon capacity uptake.
To address this, the present study performed head-to-head comparisons of the effects of several important environmental mixtures and complementary studies of putative gases.
