A successful interpretation of the complex relationship between GC RIs of methyalkanes and the chemical structure is achieved using the QSPR method.
      
The content of the volatile components in blue ballpoint pen ink were determined by gas chromatography (GC).
      
Based on the mass spectra search function of GC/qMS with the aid of the discriminability of the geometrical isomer by GC/FTIR and the ability to determine the accurate mass charge ratio (m/z) by GC/oaTOFMS, 68 GC eluants were identified successfully.
      
Compared with the results obtained by GC/qMS only, the analytical results obtained by these hyphenated methods of gas chromatography are more credible.
      
The volatile oil, the fraction of petroleum ether: EtOAc = 20:1 (V/V) on Si gel chromatography, was also quantitatively analyzed by gas chromatography mass spectrometry (GC-MS).
      
The NB-CNT/ glasssy carbon (GC) electrode was fabricated by modifying NB-CNT nanocomposite on the GC electrode surface and its electrochemical properties were investigated by cyclic voltammetry.
      
The NB-CNT/GC electrode could effectively sense the concentration of NADH, which was produced during the process of oxidation of substrate (e.g.
      
Investigation of electro-oxidation activity of Pt-CNTs/GC electrodes
      
The morphology and structure of Pt-CNTs/ GC electrodes were characterized via Transmission Electron Microscopy (TEM) and selected area electron diffraction.
      
The electro-oxidation behavior of CO and methanol on Pt-CNTs/GC electrodes were studied with cyclic voltommograms or chronoamperometry.
      
Three oxidation peaks were observed for CO absorbed on Pt-CNTs/GC electrodes.
      
Among the three oxidation peaks, peak I was presumed to be due to the bridged CO absorption while peaks II and III were attributed to the split in the linear CO which is absorbed on the Pt-CNTs/GC nanocluster with different particle size and Pt film.
      
The oxidation current of methanol on the Pt-CNTs/GC electrode did not always increase with the increase in the amount of Pt loading.
      
The purity of CPS-0 was determined by HPLC and the structure was elucidated by monosaccharide composition analysis, methylation analysis, GC, GC-MS, NMR spectral (1H-NMR, 13C-NMR, HMQC), UV, IR, and elemental analysis.
      
The volatile pyrolytic products of basswood (Tilia amurensis) specimens treated with FRW and its components guanylurea phosphate and boric acid were analyzed by GC-FTIR.
      
The sap flow measurement was used in combination with morphological characteristics of tree and forest structure to calculate the whole-tree transpiration (E), stand transpiration (Et), and mean canopy stomatal conductance (gc).
      
Analyses on the relationships between tree morphological characters and whole-tree water use, and on the responses of gc to PAR and vapor pressure deficit (D) were conducted.
      
The analyses on the responses of canopy stomatal conductance showed that the maximum gc (gcmax) changed with PAR in a hyperbolic curve (p>amp;lt;0.0001) and with D in a logarithmic one (p>amp;lt;0.0001).
      
Compounds in the profiles of volatiles from the above four species were identified and quantified by gas chromatography-mass spectrometry (GC-MS) equipped with a CP-4020 termodesorption and cold trap (TCT) device.
      
LOH and MSI of the FHIT were detected by using PCR at 4 microsatellite loci: D3S 1300, D3S 4103, D3S 1481, D3S 1234 in cancer tissues from 50 patients with primary GC, with normal mucosa acting as matched controls.
