Paper spray mass spectrometry (MS) allows for the direct analysis of pharmaceuticals, drugs of abuse, and other small molecules from blood, urine, and other biofluids (1,2).

Chromatography data systems (CDSs) have had a starring role in many regulatory citations involving falsification and fraud in analytical laboratories regulated by Good Manufacturing Practices (GMP). In this instalment of "Questions of Quality" we will examine the citations and identify the technical and procedural controls required to ensure data integrity within these systems. Although focused primarily on the pharmaceutical industry, the principles described here are applicable to all laboratories working to established quality standards.

This year's HPLC symposium was held in New Orleans, Louisiana, USA. In this review, Ron Majors covers HPLC and UHPLC column and sample preparation highlights, summarizes the awards presented, and reviews the overall liquid-phase chromatography trends.

How can resolution be determined when peak width cannot be measured?

A review of the essential elements of MS approaches to protein quantification and a critical comparison of the available options

The numerous advantages of translating gradient chromatographic methods between the differing formats of liquid chromatography (LC) have been explored and discussed.

Many problems encountered executing HPLC methods are a result of decisions made during early method development. This article discusses one critical variable in method development, the choice of stationary phase chemistry.

An efficient method for forensic analysis of amphetamines and synthetic cathinones - the illicit drugs often called "bath salts" - in hair samples.

This article describes ways to apply quality-by-design principles to build in a more scientific and risk-based multifactorial strategy in the development of an ultrahigh-pressure liquid chromatography (UHPLC) method for omeprazole and its related impurities.

A look at what's in store for chromatographers at the Analytica China Conference. The conference and the exhibition will take place at the Shanghai New International Expo Center, Shanghai, People's Republic of China, from 24–26 September 2014.

Since the gas flow required for the separation step in gas chromatography is frequently lower than that required to optimize the detection, nitrogen is used as a make-up gas to increase the gas flow for detection.
