Automated Extraction and Analysis of Isomeric Cortisone and Prednisolone
April 16th 2016A simple automated extraction method using a Tecan Freedom EVO® 100 liquid handler and Phenomenex’s Novum simplified liquid extraction (SLE) 96-well plate. Analysis of isomeric cortisone and prednisolone by UHPLC by Kinetex 2.6 μm, 50 x 3 mm core-shell Biphenyl column was used to successfully separate these two compounds and their isomers.

Drug Analysis from Oral Fluids
April 16th 2016The collection of oral fluid is gaining popularity due to the fact that it is not intrusive and easy to use. In this study we look at four different devices, and compare the results obtained for drugs varying in terms of hydrophobicity and their acidity/basicity.

Data Integrity in Pharmaceutical Quality Control Laboratories: What You Need to Know Q&A Part 2
April 15th 2016Data integrity problems in pharmaceutical quality control laboratories are driving more regulatory action than ever before. It is obvious that something has changed to drive all this activity. There is plenty of information available, but much of it seems to confuse or frustrate rather than clarify or help. In this summary, we will provide clarity, dispelling confusion by looking at the facts, based on a study of available resources and direct interactions with FDA staff and their consultants. You’ll learn from Loren Smith, Agilent’s software compliance expert and a UC Berkeley instructor with 25 years of regulated software experience, how to put the current enforcement environment in historical context, and to apply critical thinking skills to what you hear or read regarding data integrity. You’ll also learn how to evaluate your current laboratory software and associated processes against these new expectations, as well as how vendors are redesigning laboratory software to help you respond to these new realities.
Hormone Analysis by LC-MS and Water Impact
April 14th 2016The increased use of hormone-based therapies in health care throughout the world has resulted in hormones finding their way into municipal water supplies. The potential health risks of unintended consumption of hormones through drinking water have significantly increased the interest in identifying these compounds in our water supplies. The Milli-Q system incorporates a combination of purification processes that provides ultrapure, hormone-free lab water for the LC–MS techniques used for interference-free analysis of these contaminants.
Seamless Integration of Mass Detection into the UV Chromatographic Workflow
April 7th 2016Historically, UV detection has been favored in many laboratories for its ease of use, robustness, and reliability. However, some of the inherent challenges include analytes that do not have a response in a UV channel, coelutions, and unknowns, any of which can require an orthogonal approach such as mass detection. While mass detection offers a number of benefits when used in tandem with UV detection, incorporating it into an existing UV workflow can be time-consuming and laborious.

Fast, Cost-Effective IC Methods for Testing Environmental Waters
April 7th 2016Ion chromatography (IC) is a well-established technique for monitoring inorganic anions in environmental waters around the world. It is approved by the U.S. Environmental Protection Agency (U.S. EPA) for compliance monitoring of primary and secondary inorganic anions in drinking water and has been validated by European standards organizations, including the International Standards Organization (ISO). These agencies have published IC methods for the analysis of inorganic anions in drinking water, groundwater, and wastewater. These methods can be made faster and more cost-effective, however, by using the latest IC technologies, including high-pressure IC. In this summary, we will discuss regulatory compliance testing of municipal drinking water and wastewater, and how this testing can be made faster and more cost-efficient through the use of high-pressure-capable ion chromatography systems.
Extraction Method for Pesticides in Poultry Fat
Using a targeted solid phase extraction (SPE) method and GC–ECD analysis, chlorinated pesticides are extracted from poultry fat resulting in a method that decreases the amount of labor and reagents when compared to the USDA-FSIS CHC2 method.

Extraction of Cannabinoids from Brownies
April 7th 2016Cannabinoids are successfully extracted from a complex brownie matrix using the QuEChERS sample preparation technique, significantly reducing the presence of matrix interferences. The resulting clean samples are analyzed by GC–MS using a specialized deactivated GC column to provide heightened peaks for the cannabinoid compounds.
