This webinar will describe the use of molecular spectroscopy techniques (Raman and IR) for solid-state analysis in drug development. Two presentations will focus on chemical imaging of polymorphs by LDIR, and the rapid quantification of low level crystalline forms using transmission Raman.
Read MoreIn this webinar, production process and quality managers, engineers and technicians will learn how to easily avoid very costly contamination and lost production batches.
Read MoreAmino acids as building blocks of peptides and proteins are present in animals, humans and plants. The analysis of amino acids is of essential significance in several areas including food science, clinical diagnostic and pharmaceutical products research. The classical LC determination of amino acids is performed by the sample pretreatment including pre-column as well as post-column derivatization increasing or even enabling spectroscopic detection.
Read MoreYin-Chen-Hao-Tang is a traditional Chinese medicine consisting of a mixture of three herbs, but there is some controversy as to the best way to prepare it. Researchers from the Shanghai Institute of Materia Medica and the Southwest University of Science and Technology (Mianyang, China) used chemometric techniques to compare the traditional and modern methods of producing Yin-Chen-Hao-Tang.
A proteomic study of the hair follicles of men following low-level laser therapy to reverse the common form of hair loss known as androgenetic alopecia has highlighted the proteins involved and supported the use of this form of treatment.
Oxygenation of heavy petroleum fractions can produce more valuable products, but the analysis of the resultant complex mixture is challenging owing to the many species present. Researchers from Sasol’s laboratories in Sasolburg (South Africa), the University of Pretoria and Tel Aviv University used initial purification by solid-phase extraction or supercritical fluid chromatography followed by separation by GC-MS with supersonic molecular beams to separate a mixture of oxygenated petroleum...

For some time “sustainable processes” has been the phrase on everyone’s lips. As far as analytical labs are concerned there are many possibilities for saving energy or rather for using resources more efficiently. Besides the real “energy guzzlers” such as extractors and safety cabinets, complex analysis apparatus has to be subjected to critical system checks, too.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...

In this video clip, the “Magic Triangle” for the selection of stationary phases for GPC/SEC/GFC is presented by Dr. Daniela Held (Director Marketing and Sales, PSS). This tool provides a quick visual aid for the selection of columns, where the three sides represent sample, mobile phase, and stationary phase.
