Antioxidant screening using thin-layer chromatography
Figure 1 shows that hexane-ethanol solvent system exhibited more separation when hexane is in larger amount.
Based on these findings, alkaLoidal extract from leaves was fractionated on preparative thin-Layer chromatography
in a bioassay-guided fractionation affording individual purified ramiflorines A and B.
Silicic acid thin-layer chromatography
of conjugated and free bile acids.
The First Check Home Drug Test thin-layer chromatography
process takes place on each of the test strips of the test lid.
The probe can sample dried drugs or proteins from wells on microtiter plates; dyes, inks, and pharmaceuticals separated on thin-layer chromatography
plates; pharmaceuticals from MALDI plates; drug excretion via skin; and other applications for biological sciences.
Use of thin-layer chromatography
for detection of 11-nor-9-carboxy-delta 9-tetrahydrocannabinol in urine.
The fraction D was further fractionated by thin-layer chromatography
(TLC) to fractions A' to G'.
The reference also explores recombinant proteins and proteomics, DNA sequencing and oligonucleotide analysis, capillary electrochromatography, simulated moving bed processes, ion-exchange chromatography, and thin-layer chromatography
The liquid solvent then can be analyzed by thin-layer chromatography
and gas chromatography-mass spectrometry (GC-MS) in electron impact (EI) and/or chemical ionization (CI) mode.
Many of us first experienced thin-layer chromatography
in junior-high-school science labs.
According to thin-layer chromatography
data, benzene solubles, the yields of which were equal in semicoking and water conversion experiments, varied greatly in componental composition (Fig.
(TLC) is used to monitor the progress of the reaction.
Fat characterisation: Saponification value: Iodine value; Free fatty acid value: Peroxide value: Thin-layer chromatography
separation of simple lipids.
Using a gas chromatography-electron capture detector (GC-ECD), a GC-mass spectrometer (GC-MS), GC-microconductivity, thin-layer chromatography
, ultraviolet-spot in situ scanning spectrum, and element analysis, we identified PC[B.
can also be employed to detect saturated hydrocarbons.
