1. SEC2020 Spectrometer system
The SEC2020 Spectrometer system is a compact spectrometer system developed by ALS
Co, .Ltd and provided by BAS Inc. One unit can measure a wide wavelength range from
ultraviolet to near infrared (UV/VIS/NIR) with high sensitivity, corresponding to optical
measurements such as spectrum, absorbance, transmittance, reflectance , fluorescence,
light source and concentration.
In addition, BAS, which also provides electrochemical measuring instruments, may also
offer know-how for spectroelectrochemical measurement, electrochemical
measurements combined with spectroscopy.
* Optional products may be prepared separately.
