As the global population steadily increases, it is important that sufficient crops are produced each year to provide enough food, clothing, and other products. Crops such as corn, wheat, soy, and cotton receive nutrients from the soil they are grown in. Fertilizers play a crucial role in providing these crops with the nutrients they need to grow properly.

Introduction
Raman spectroscopy is a widely used physical characterization technique in the pharmaceutical industry. In particular, Raman spectroscopy is used to identify different polymorphic forms. The physical and chemical performance of drugs, excipients, and packaging materials are dependent on the presence of and interaction with water vapor. The combination of Raman spectroscopy and vapor sorption techniques allows for a more comprehensive understanding of vapor-s

Edible oils are not only a major source of nutrition but also a key basic material in the food industry. Vegetable oils are increasingly important because of their high content in mono- and polyunsaturated fatty acids in comparison with animal fats. In this application note, the main ingredients of olive oil, camellia oil, arachis oil, sunflower seed oil, and colza oil are analyzed using a portable Raman spectrometer combined with chemometrics software from B&W Tek.

Abstract
Carbon black is a form of amorphous carbon. It is mainly used as reinforcement filler in automobile tires and other rubber products, but is also used in pigments, paint, and carbon paper. Raman spectroscopy is a very effective analytical technology to characterize carbon materials. The Raman bands associated with different carbon bonds reveal details of the structure on the molecular level. Most of the research using Raman technology has been applied to carbon n

This technical digest covers the fundamentals of raman spectroscopy and instrumentation. Topics include the history of raman spectroscopy, what raman is and how it works, raman instrumentation, and common applications.

Introduction
Law enforcement officers responsible for reducing narcotics trafficking and drug abuse face more challenges than ever before. New drugs are appearing at an alarming rate and the global drug problem is spiraling out of control.

Metrohm is proud to announce the launch of the i-Raman NxG, a next-generation laboratory Raman spectrometer designed to enhance precision and performance in routine quality control measurements. The i-Raman NxG continues Metrohm`s tradition of quality, offering advanced features that enable faster measurements, improved sensitivity, and greater sampling flexibility.

Spectroelectrochemistry (SEC) is among one of the most promising emerging analytical techniques. While commercial spectroelectrochemical instruments have been developed to facilitate the performance of SEC experiments, the absence of user-friendly cells has limited the development of the technique until now. This article describes these different kinds of SEC cells in detail.

Choosing the right eluent in chromatography is crucial—especially for ion exchange chromatography (also known as ion chromatography or IC)—as is the choice of the correct column. Both must work in harmony to achieve optimal separation performance. In chromatography, we often refer to the «triangle of dependency» – the interdependent relationship between analytes, the stationary phase, and the eluent. This blog post focuses on the eluent-part of this triangl
