hplc micro insert for valuable samples with label from Sigma

Determination of Drugs by Online Column-Switching

As a sample for the HPLC methods based on UV detection,a micro-extraction method with molecularly imprinted polymers was developed by Du et al. and applied to the pork samples (). CLEN was also determined in pork samples by SPE coined with dispersive liquid–liquid micro-extraction.

Surface enhanced Raman spectroscopy in microchip

16/3/2020· Raman spectroscopy is a valuable analytical tool for the chemical identifiion of compounds,based on monitoring vibrational changes in a molecule after inelastic stering of interacting hplc micro insert manufacturerns. However,since inelastic stering is a rare phenomenon (it is estimated that only 1 hplc micro insert manufacturern from 10 6 provides Raman signals),Raman spectroscopy suffers from low signal intensity.
