Abstract EN
We report on a thin layer chromatograph (TLC) with a built-in surface enhanced Raman scattering (SERS) layer for in-situ identification of chemical species separated by TLC.
Our goal is to monitor mixture samples or diluted target molecules suspended in a host material, as happens often in environmental monitoring or detection of food additives.
We demonstrate that the TLC-SERS can separate mixture samples and provide in-situ SERS spectra.
One sample investigated was a mixture consisting of equal portions of Raman-active chemical species, rhodamine 6 G (R6G), crystal violet (CV), and 1,2-di(4-pyridyl)ethylene (BPE).
The three components could be separated and their SERS spectra were obtained from different locations.
Another sample was skim milk with a trace amount of melamine.
Without development, no characteristic peaks were observed, but after development, a peak was observed at 694 cm−1.
Unlike previous TLC-SERS whereby noble metal nanoparticles are added after development of a sample, having a built-in SERS layer greatly facilitates analysis as well as maintaining high uniformity of noble metal nanoparticles.
