Labconco Corporation, a supporter of HPLC Users Group, would like to introduce our next generation Vacuum and Nitrogen RapidVap systems. Some features of these systems are a new look, easy to set programming with up to nine different user-set programs, larger sample sizes and the ability to run Class 1, Group D solvents in the vacuum system. These new units will be available in September. For more information on our RapidVap and other Labconco products, please call us at 1-800-821-5525 or visit us at the American Society for Microbiology in Chicago from May 31 to June 2. Our web address is www.labconco.com.

The site now uses a lot of Java and scripts which may result in slower performance on some computers. If you have problem or access is extremely slow, please let me know.
04-14-1999 Message from chairperson:
At this moment, I can tell you that the annual HPLC User's Group meeting will be on June 1, 1999 from 6:30 to 9:00! I have been granted a hotel by ASM but before I book such an expensive place, I'd like a show of hands as to who will be there. So please email this list [ListServ] if you will be attending. There will be an official announcement as soon as the location has been determined.
Linda

I have the intention of setting up a message board in addition to the listserv we currently have. If anyone has any feedback, please e-mail me. Mainly I am interested in finding out if you think there is a utility for it.
03-05-1999 The addition to the standardized manual, Mycolic Acid Pattern Standards, has been finalized and is available for download. MAPS manual can be downloaded/viewed [HERE]. Adobe Acrobat is needed. Visit FAQ section for more information on Acrobat.
02-14-1999 Gary Cage:
I thought you might like to see an HPLC pattern of "Mycobacterium canettii". This is from an isolate (NZM 217/94) kindly sent to me by Dr Gaby Pfyffer of the Institut f�r Medizinische Mikrobiologie der Universit�t Z�rich.
Dr Pfyffer recently published a reference to this organism in the October-December 1998 issue of Emerging Infectious Diseases [Pfyffer, GE, R Auckenthaler, JDA van Embden and D van Soolingen. 1998. Mycobacterium canettii, the smooth variant of M. tuberculosis, isolated from a Swiss patient in Africa. Emerg Infect Dis 4:631-634]. It was initially described as part of the M. tuberculosis complex [van Soolingen, D, T Hoogenboezem, PE de Haas, PW Hermans, MA Koedam, KS Teppema, PJ Brennan, GS Besra, F Portaels, J Top, LM Schouls and JD van Embden. 1997. A novel pathogenic taxon of the Mycobacterium tuberculosis complex, Canetti: characterization of an exceptional isolate from Africa. Int J Syst Bacteriol 47:1236-1245].
The HPLC pattern looks like M. tuberculosis (surprise!). More information can be obtained from Dr Pfyffer via her email address: [email protected].

02-12-1999 Linda Guthertz, Chairperson's resignation letter:
It is with regret that I submit this letter of resignation to the HPLC Steering committee.
I have served as chairperson since 1992 and feel that as of June 1, 1999, it will be time for someone with fresh thoughts and ideas to take over.
I have done what I could to make this a vital group and to promote the HPLC technique within the public health community. It has been a pleasure to work with all of you.
Sincerely,
Linda S. Guthertz
