Blood and sputum are the most common means of detection by diagnostic tests, but producing adequate sputum can be difficult given a dry cough is often a TB symptom.

Because the biophysical and biochemical parameters of peripheral blood plasma are often greatly altered in monoclonal gammopathy, conventional mass spectrometry measurements can be limited.

Researchers utilized individual ion mass spectrometry to analyze the heterogeneous glycan profiles of recombinant coronavirus spike proteins, detailing their structural intricacies.

Researchers from Nanjing University of Chinese Medicine leveraged ultrahigh-pressure liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC–QTOF-MS) and network pharmacology to identify potential quality markers of three processed Qingpi products and elucidate their mechanism in liver disease treatment.

A recent study out of Jeonbuk National University evaluated data integration methods for the isotopic analysis of lead at ultratrace levels.

Researchers employed advanced chromatography and mass spectrometry techniques to unravel the chemical components and metabolites of Lingbao Huxin Dan, pinpointing its therapeutic potential for cardiovascular ailments.

Scientists in Mexico developed a new method for detecting herbicides in agricultural soil, being based on techniques like 9-fluorenylmethyl chloroformate (FMOC-Cl) and ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).

Weronika Hewelt-Belka, an assistant professor at Gdańsk University of Technology in Poland, answers questions about her research analyzing GM3 gangliosides in human milk, elucidating their molecular distribution and dynamic changes throughout lactation.

The process was assisted by pH-dependent acid-base partitioning coupled with salting-out-assisted liquid-liquid extraction (LLE).

A recent study from the Shangdong Academy of Chinese Medicine examined chicory using a novel UHPLC–HRMS technique and rats as the test subject.

A polydimethylsiloxane (PDMS) silicone rubber band sampler was used to collect volatile organic compounds (VOCs) from the skin of both tuberculosis (TB)-positive and TB-negative subjects.

Scientists from Utah and Ireland recently created a liquid chromatography–mass spectrometry (LC–MS) analytical method capable of detecting phototoxins in essential oils.

In our second edition of “Inside the Laboratory,” Zhibo Yang, PhD, an associate professor of chemistry at the University of Oklahoma, discusses his group’s most recent work in single-cell mass spectrometry (MS) and MS tissue imaging.

LCGC and Spectroscopy Editor Patrick Lavery spoke with Oligo Factory CEO Chris Boggess about the company’s recently attained compliance with Good Manufacturing Practice (GMP) International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) Expert Working Group (Q7) guidance and its distinction from Research Use Only (RUO) and International Organization for Standardization (ISO) 13485 designations.

Non-alcoholic beers are becoming more popular and need to reflect the sophisticated flavourings of beers that are brewed containing alcohol. Sophisticated analytical techniques can help to achieve this.

Rolduc 2024 takes place from 28–30 April 2024 in Rolduc Abbey, Kerkrade, The Netherlands.

Scientists in Xi’an, China have created a novel system for the analysis of cell membranes, based around haloalkane dehalogenase protein tag (HALO)-tag technology. Their research was published in Talanta.
