摘要: Abstract A new chiral sensor based on weak measurement to accurately measure the optical rotation (OR) has been developed for estimation of a trace amount molecule. With principle in frequency domain, central wavelength shift output spectra is quantitatively relative angle preselected polarization. Hence, molecule (e.g., L-amino acid, or D-amino acid) can be enantioselectively determined by modifying preselection with OR, which will cause polarization plane. The concentration sample, corresponding its activity, analyzed spectra, collected real time. Immune refractive index change, proposed valid complicated measuring circumstance. detections Proline enantiomer different solvents were implemented. results demonstrated that acted as reliable method recognition enantiomers diverse circumstance merits high precision and good robustness. In addition, this real-time monitoring approach plays crucial part asymmetric synthesis biological systems.
