The apparatus used for the GC-FID
analysis was composed of a gas chromatograph and a Rxi[R]-5 ms column as described above.
method to determine styrene in polystyrene glasses.
Qualitative and quantitative analysis of the PAHs were carried out using GC-FID
and GC-MS as mentioned above for water analysis .
Keywords: Trifluoroacetylacetone, Gamma aminobutyric acid, Putrescine, Amino-acids, Cerebrospinal Fluid, GC-FID
There are pairs of distinguishing peaks of n-alkanes and n-1-olefins in the GC-FID
chromatograms of MD.
Figure S1: representative GC-FID
chromatograms of specificity study.
Some analytical parameters of the method were determined from the calibration curve plots for each compound by the standard addition method, in which portions of the caja-manga pulp were spiked with pesticide standards in different concentrations, 0.17 to 11.75 [micro]g x [g.sup.-1], submitted to the optimized SLE-LTP, and the extracts were analyzed by GC-FID
. The analytical parameters obtained for the method are presented in Table 2.
Gas chromatograph-flame ionization detection (GC-FID
) was used in this study to determine the composition of FFAs.
Composition of essential oil was determined by GC-FID
using 1 [micro]L of diluted sample in hexane (1:100).
analysis provided nine fatty acids (96.7%), as shown below in the chromatogram of Figure 1 and in Table 1.
0.1 mL of the mixture was withdrawn and added to 1 mL of the solvent for GC-FID
analysis at [T.sub.0].
The fatty acids in the fat from casein and serum were made into their methyl ester by saponification followed by esterification and analyzed by GC-FID
. Palmitoleic, oleic and linoleic acids were predominant fatty acids found in the analyzed samples while stearic, arachidic, behenic and myristic acids were present as minor acids.
