A copolymerized gel composed of poly(N-isopropylacrylamide) and acrylic acid was used to construct a mechanism that withdrew sample solution slowly. A gel of 11 mm × 11 mm × 4 mm was used and a volume change was caused by changing the temperature, changing the temperature and pH, and using a pH chan

A personal computer-based on-line monitoring and controlling system was developed for the fermentation of microorganism. The on-line HPLC system for the analysis of glucose and ethanol in the fermentation broth was connected to the fermenter via an auto-sampling equipment, which could perform the pi
## Abstract The paper studies the utilization of attenuated total reflectance–Fourier transformed infrared (ATR–FTIR) and Raman spectroscopy to investigate isothermal semi‐batch precipitation of a model compound, L‐glutamic acid. ATR–FTIR spectroscopy was mainly used for in‐line monitoring of the s
## Abstract **Summary:** A new error‐in‐variables method was developed to estimate the reactivity ratios in copolymerization systems. It brings the power of automatic, continuous, on‐line monitoring of polymerization (ACOMP) to copolymerization calculations. In ACOMP systems, monomer and polymer co
