JASCO CPL Spectroscopy
Circularly polarized luminescence (CPL) offers different and complementary information to other chiroptical techniques such as Optical Rotatory Dispersion (ORD), Circular Dichroism (CD), Vibrational Circular Dichroism (VCD), and Raman Optical Activity (ROA), since it reflects the structural properties of the excited state. CPL signal itself is the intensity difference between left and right circularly polarized light […]
Analysis of Microplastics
Analysis of Microplastics are possibly the greatest hazard to the environment since the ozone layer depletion and global warming. Unfortunately for life on Earth, microplastics are now spread across the entire planet. The race is on to identify the nature, cause, and effects of these materials, and to find suitable remedies for environmental clean-up. Scientists […]
qHOS – Higher order structure similarity evaluation software
The demands of therapeutic antibody are increasing day by day, and CD spectroscopy attracts attention as the tool for assessing the higher-order structure of proteins quickly and easily. The international council for harmonization ICH-Q6B guideline recommends CD spectroscopy as one of the methods for physicochemical characterization of biopharmaceuticals, and there is the requirement for an […]
MIX Observation
In Raman microscopy, the quality of sample observation is essential for identifying suitable measurement points. The NRS Series of Raman spectrometers can be used with various types of observation: Bright-field (epi-illumination), Bright-field (transmitted illumination), Dark-field, MIX, Polarized and Differential Interference. This article introduces two of these methods: Dark-field and MIX observation, which are recommended for […]
