Historically, 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.
Data 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.
Ion 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.
The objective of this application note is to demonstrate that the ACQUITY QDa Detector provides a simple and cost-effective solution for detecting oligonucleotides across a wide molecular weight range and can be readily integrated into existing UV-based workflows.
This summary will explore the latest developments in the analysis of contaminants of emerging concern in drinking water. We will explore the requirements and results from the EPA’s Unregulated Contaminant Monitoring Rule 3 program for Perfluorinated organics, and hormones. After a brief overview of the EPA analytical techniques, we’ll take a look at new technology and ask how it compares for both and if it can find compounds we didn’t even know were there.
The validation process of an analytical method is a complex and demanding activity, consisting of many time-consuming steps. Empower® 3 Method Validation Manager (MVM) automates the method validation workflow within a single software environment, reducing time and ensuring conformance to the validation requirements and acceptance criteria defined in the protocol. This application note demonstrates validation of a UPLC® method for metoclopramide HCl and related substances using Empower 3 MVM.
Hamilton polymeric PRP-X100 and PRP-X110 anion exchange columns are the easy way to separate inorganic and organic anions from 10 ppb to 500 ppm without elaborative preconcentration or suppression.
Uncertainty in chromatographic method development and quantitative experiments often arises. RADAR can detect uncertainty, discover co-eluting compounds, collect full scan MS data and monitor the background matrix, enabling fast method development.

The Pharmaceutical Inspection Convention and Pharmaceutical Inspection Co-operation Scheme (jointly referred to as PIC/S) provide good manufacturing practice (GMP) guidance for the lifecycle of a product. The scope of this executive summary is to provide a brief high-level overview of GMP, the impact of PIC/S, and compliance with the PIC/S document PE 009-12 “Guide to Good Manufacturing Practice for Medicinal Products Annexes“ Annex 11 Computerized Systems.
UCT’s approach for the analysis of anabolic steroids from serum utilizes a traditional reversed phase interaction, but also features the addition of strong-anion exchange functionality (QAX) within the sorbent. This added functionality aids in the removal of unwanted matrix components commonly found in serum such as amino acids and inorganic ions. To prove the effectiveness of this approach, a comparison study was conducted using UCT’s recommended sorbent for steroid analysis (C8 + QAX) versus a traditional SLE, diatomaceous earth sorbent.
