“…4). The Raman spectra are in a good agreement with literature data [25], including the sequential hydrolysis of a tin(II) chloride solution and reference data from abhurite, Sn II 21 O 6 Cl 16 (OH) 14 , and hydroromarchite, Sn II 3 O 2 (OH) 2 [15], as well as both minerals [10]. In the case of abhurite, a characteristic strong Raman signal at 206 cm −1 was observed next to a medium band at 256 cm −1 .…”

“…The stability range of abhurite and its transition to hydroromarchite depending on the pH value has been discussed [13]. Edwars et al [8] 2013, Chen and Grandbois [15] reported in situ Raman spectroscopic investigations of the sequential hydrolysis of tin(II) chloride to abhurite, hydroromarchite and finally to romarchite, Sn II O. Their research demonstrates the formation of abhurite from a tin(II) chloride solution by adding a sodium hydroxide solution.…”

The goal of this annual review is to provide an overview of advances in the field of Raman spectroscopy as reflected in articles published each year in the Journal of Raman Spectroscopy as well as in trends across related journals that have published papers in the broad field of Raman spectroscopy. The content is obtained from statistical data on article counts obtained from Thomson Reuters ISI Web of Knowledge by year and by subfield of Raman spectroscopy. Additional information is gleaned from presentations at the XXIV International Conference on Raman Spectroscopy in Germany in August 2014 and those featuring Raman scattering at SCIX 2014 organized by the Federation of Analytical Chemistry and Spectroscopy Societies in Reno, Nevada, USA in October 2014. Coverage is also provided for topics from the conference GeoRaman 2014 held in June in St. Louis, Missouri and ECONOS 2014 held in May in Dole, France. Finally, papers published in JRS in 2013 are highlighted and arranged by topics at the frontier of Raman spectroscopy. From these various perspectives, it is clear that Raman spectroscopy is a rapidly expanding field that provides sensitive photonic information of matter at the molecular level in an ever‐widening sphere of novel applications.

“…Currently selected conventional offline amino acid analysis methods that use high‐performance liquid chromatography (HPLC) or an amino acid analyser are not suitable for process monitoring, mainly due to long intervals between sampling and obtaining analytical results caused by time‐consuming procedures. In recent years, in a variety of fields, the hydrolysis process has been studied and monitored by different spectroscopic sensors, including near‐infrared (NIR) spectroscopy, infrared (IR) spectroscopy, Raman spectroscopy, ultraviolet–visible (UV–Vis) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy and other spectroscopic sensors . In the TCM pharmaceutical industry, NIR spectroscopy‐based methods were developed by Wu et al .…”

Objectives Cornu Caprae Hircus (goat horn, GH), a medicinal animal horn, is frequently used in traditional Chinese medicine, and hydrolysis is one of the most important processes for GH pretreatment in pharmaceutical manufacturing. In this study, on‐line Raman spectroscopy was applied to monitor the GH hydrolysis process by the development of partial least squares (PLS) calibration models for different groups of amino acids. Methods Three steps were considered in model development. In the first step, design of experiments (DOE)‐based preprocessing method selection was conducted. In the second step, the optimal spectral co‐addition number was determined. In the third step, sample selection or reconstruction methods based on hierarchical clustering analysis (HCA) were used to extract or reconstruct representative calibration sets from the pool of hydrolysis process samples and investigated for their ability to improve model performance. Key findings This study has shown the feasibility of using on‐line Raman spectral analysis for monitoring the GH hydrolysis process based on the designed measurement system and appropriate model development steps. Conclusions The proposed Raman‐based calibration models are expected to be used in GH hydrolysis process monitoring, leading to more rapid material information acquisition, deeper process understanding, more accurate endpoint determination and thus better product quality consistency.
