Kevin McNally, IT Manager attending the IVT Conference Electronic Records/Signatures and Computer Validation

Hi Ludwig first of all let me say that I have just attended the Dublin conference and to be honest I was genuinely surprised. I suppose, as an IT person, I am always a little suspicious when dealing with Validation experts. I have to say that I learned more with attending your talks this week than I have learned in the last 4 years working in a regulated environment. If only all people spoke as clearly and logically as yourself then perhaps a lot of the confusion and fear would not exist anymore
I do appreciate the attention and service you give. It is very refreshing these days to see such professionalism and dedication.

Jim Remillard, Information Systems Manager, Associates of Cape Cod, Inc.

Ludwig -

Thanks so much for the ppt files with your network presentation. Our IS department was impressed! The audit trail presentation is also excellent. Our software development team will be studying these as we design our new software. Now I don't feel so bad about missing your presentation because the slides speak for themselves! You present some tough issues that IS managers and software designers have to deal with to be compliant and it's encouraging to see you take them head-on. Thanks again, Ludwig and I'll see you at one of the upcoming IVT meetings.

Sandra Harris, CV Therapeutics, about a Part 11 Seminar

Dr Huber,

A quick note… I have attended quite a few of your Webinars through IVT and LabCompliance. I just wanted to tell you how much I have enjoyed them. You’re a very good speaker and the content is always relevant to what I am doing here especially with respect to Computer Systems Validation.
Thanks!, Sandra

Dr. Patrick G. McCormick, SkyePharma, about Ludwig Huber's 21 Part 11 Video

Dear Dr. Huber

Having seen this one hour presentation, I must tell you it is the best introduction to Part 11 I know of. It would be extremely helpful to SkyePharma Inc if we could have a copy of this CD for use in our GMP training classes.

Vandana Bhatia, K Merck & Co., Inc., about books from Ludwig Huber

Mr Huber
I want to thank you for writing the best validation papers that one can follow so easily, and also understand with the first reading. I save my salary to purchase your material and have been applying your concepts and techniques within my company for QA AND VALIDATION.
Thank you once again

Doug Finner, KMC Systems Inc.About the Validation Master Plan

Our remediation team finds the VMP (Validation Master Plan) to be a very complete and well written document. As the project leader for our remediation effort, I find that the document moves the discussion away from 'what does Doug say we should do - why does he say that' to 'how do we best create an environment that fits our needs'; it really makes the discussions more issue rather than person focused and I thank you for providing that help.


Stephanie Brown, Quality Chemlabs,  about the GLP/GMP primer

Chapters 1 & 2 are excellent tools for training new employees - especially those that are new to the GMP environment. The entire guide is an excellent resource when generating SOPs when used in conjunction with the CFR and FDA guidelines. Our plan is to incorporate some of the info presented in your primer into our initial training for new employee

Dr. David Grace, Nycomed Amersham Imaging

To Ludwig Huber:

I have recently downloaded a copy of your GLP and cGMP primer which I am part way through reading at the moment I also am reading your Validation and Qualification in Analytical Laboratories which we have purchased. I really must congratulate you on and thank you for the clarity of your explanations and the wealth of examples and practical suggestions - I have some knowledge in the field but need a lot more and both these publications are ideal for me.

Best wishes.

Joel C. Harder, Quality Assurance Associate at the United States Red Cross,

Joel is involved at the headquarters level in developing policy pertaining to a validation program.

He wrote:

I utilize L. Huber's articles (the ones that I am aware of) to provide guidance to the field in an effort to provide further understanding of validation principles. Using his articles as a base (in addition to many others) has improved our organizations understanding of validation principles. The field struggles at times getting the language since it is pharmaceutical based but I am happy to report that there are positive end results. Hence, I believe that efforts on his part to continue to generate comprehensive and concise articles has increased the safety of the blood supply, which in my opinion is very safe. I appreciate his efforts and look forward to reading more of his articles pertaining to validation principles in general. Thanks.

Michelle Bailey, Sr. Validation Specialist, Validation Systems Inc., Palo Alto, CA

There are many good references that exist on the topics of HPLC Calibration and Validation. They are two different areas, but they go hand in hand. Of the references I have reviewed the best written and easily understood are those published by Ludwig Huber Ph.D., an expert in the field. I highly recommend the two books he's published: "Validation of Computerized Analytical Systems", Interpharm Press, 1995 "Validation and Qualification in the Analytical Laboratory", Interpharm Press, 1998 He has written and collaborated on a great number of articles in LC-GC, Biopharm and other reputable reference sources. He has a website at www.labcompliance.com. You should try this site as a starting point.


Dan Berdovich, QA/Regulatory Affairs Mgr , Micro Measurement Laboratories, Wheeling, IL

Your book "Validation of Computerized Analytical Systems" shed more light on the issues involved in validating particle sizing and particle counting equipment than any other single publication I've read. I've been able to help several of our clients sort out many issues involving routine qualifications with these instrument.


Dr. Herman Lam, Ph.D., Book Review for Lab Focus Magazine

Book Title: Validation and Qualification in Analytical Laboratory.
Author: By Ludwig Huber

(Interpharm Press, Inc. Buffalo Grove, IL, USA., 1999, ISBN: 1-57491-080-9)

This book is an excellent guide to two very important aspects of instrumental analysis: Instrument Qualification and Method Validation. The reliability of the data is critically affected by their proper execution. The first three chapters cover analytical system validation strategy, cGMP requirements, and the expectations of regulatory agencies and international quality establishments such as ICH and ISO. Chapters 4 to 7 provide comprehensive coverage in the approaches and requirements for Design Qualification (DQ), Installation Qualification (IQ), Operation Qualification (OQ) and Performance Qualification (PQ). The qualification of an HPLC system is used as an example to assist understanding of the qualification processes. In addition, a very useful list of OQ testing and acceptance criteria for a wide range of analytical laboratory instrumentation, and selected case studies are included in appendix B and D. Qualification of software, including the use of Macros, and computer systems are briefly discussed in chapter 8. Details on computerized system validation can be found in Dr. Huber’s book on "Validation of Computerized Analytical System" published in 1995 by Interpharm Press Inc.

Although the principles and practices of analytical method validation have been extensively discussed in the literature, the presentation of these topics in chapter 9 of the book is well organized and easy to follow. It provides a stepwise guide to perform validation for quantitative and qualitative methods. Subtle differences in some of the validation parameters such as selectivity and specificity; as well as reproducibility and repeatability are well defined and explained.

The useful discussion on the use of reference standards, their traceability and certification in Chapter 11 are definitely worth reading. It helps to clarify some of the key concepts in the use, selection and generation of reference standards in the GMP analytical laboratories.

Dr. Huber's new book on Validation and Qualification in Analytical Laboratory is a very resourceful reference. As a lab manager, who oversees instrument qualification and system validation in pharmaceutical R&D laboratories, I strongly recommend this book to all scientists working in the fields of analytical instrument qualification and method validation.

Dear Dr. Huber,
Thanks for the book chapter.
I have read your article about Validation of Analytical Methods.
I found it very useful, I do not have my doubt about validation of standard methods anymore.
