A recent stimulus to the review process article by the United States Pharmacopoeia (USP) Expert Committee is proposing a major change in the way regulated laboratories develop, validate and control analytical procedures. Is this Quality by Design (QbD) for the chromatography laboratory?

The concluding part of the article from last month's "Question of Quality" on what "complete data" actually means in practice.

This article will explore what is meant by "complete data" in the context of a chromatography data system and, with an analysis of FDA 483 citations, explore the problems when a laboratory fails to understand this phrase.

Answers to common questions about operational qualification software.

Answers to common questions about operational qualification software.

Written procedures used by trained staff are the basis for all quality systems but there are many ways of writing a procedure. Are you getting it write?

The new version of EU GMP Annex 11 has been effective for about a year. There are new technical requirements in the Annex – do your laboratory computerized systems comply with them all? In this column we look at the impact of these new regulatory requirements for Good Manufacturing Practice laboratories.

Mistakes or fat finger moments are part of human nature but where is the dividing line between this and falsification and fraud?

The results of a recent survery on stationary phases used in high performance liquid chromatography (HPLC) are revealed.

A look at the role of system suitability tests (SSTs) during performance qualification (PQ).

How will the new revision of EU GMP Annex 11 on Computerized Systems and Chapter 4 on Documentation affect chromatographers?

Can you qualify or calibrate your chromatograph using a system suitability test? No. However, for the doubters among you I'll spend the rest of this two-part article series explaining why.

The concluding part of the series on the role of system suitability tests in the pharmaceutical industry.

The author examines the process of validating a CDS and describes the trials along the way such as speed of validation, risk management, and so forth.

Can you qualify or calibrate your chromatograph using a system suitability test? No. However, for the doubters out there this column will explain why.

There is a new FDA Commissioner who wants a "strong FDA". Chromatographers must be prepared to be compliant and remain compliant - or else!

This article discusses the business benefits of interfacing laboratory applications together to eliminate paper and streamline working practices.

United States Pharmacopeia (USP) general chapter 1058 on analytical instrument qualification (AIQ) has finally become official and was released in August 2008 in the first supplement to the USP XXXI.1 This column reviews AIQ and discusses the impact it will have in the regulated chromatography laboratory.

This column discusses the similarities and differences between the validation approaches for analytical methods for QC product analysis and bioanalysis.

The regulatory world and associated guidance documents within the pharmaceutical industry is changing rapidly. This column gives an overview of what's happened since the start of the year.

You may work in a chromatography laboratory to quality standards but do you work to Good Laboratory Practice? Probably not...

The four eyes approach is a cornerstone of any quality system (GMP, GLP or ISO 17025): a first person performs a task and a second person checks it.

Information from guidance documents used in clinical investigations can be very useful to help meet FDA regulations regarding computer security in analytical laboratories.

Users need to understand not only the operation of the computer system as required by their access privileges, but also the ethics and integrity required operating under any of the GMP or GLP quality systems.

The fundamental aim of any computerized system validation should be to define its intended use and then test it to demonstrate that it complies with specification.

The best parts of the GAMP laboratory system GPG are the life cycle models for both development and implementation of computerized laboratory systems.

Part 2 of the column explores using the right balance for the right job in the right way.

The implementation and validation of a new site-wide chromatography data system for a major active pharmaceutical ingredient custom manufacturer provided the opportunity to map and optimize the GMP and ISO business processes to use electronic signatures effectively. This article describes the process optimization and how it integrates with the validation activities of the system. This overall approach provides substantial business benefits from the use of electronic signatures as evidenced by the savings resulting from process improvement and by the fact that the non-GMP laboratories implemented a similar process to analyse and approve results electronically.

Bob McDowall stresses the importance of using accurate and precise time and date stamps to ensure the integrity of the data and results generated by computerized systems in any chromatography laboratory.

The authors consider the impact an analytical balance can have on the quality of chromatographic analyses.
