WASHINGTON, March 23, 2010 — News media and others interested in the chemical sciences are invited to join the next in a series of American Chemical Society (ACS) Webinars, focusing on Professional Growth and Development.

Scheduled for Thursday, April 1, 2 – 3 p.m. Eastern Time, the free webinar will feature Walter Hammack with the Florida Department of Agriculture, as he discusses the various chromatographic tools, methods and regulations for food safety. His topic: “How Chemistry is Keeping Your Food Safe –Application of Ultra High Pressure Liquid Chromatography (UHPLC) in a Food Safety Laboratory.”

The ACS Webinars connect you with subject experts and global thought leaders in chemical sciences, management, and business to addresses current topics of interest to scientific and engineering professionals. Each webinar includes a short presentation followed by a Q & A session.

News media and scientists can tune into the conference without charge, but must register in advance.

Hammock’s topics will include:

  • What is ultra high pressure liquid chromatography (UHPLC)?
  • Advantages of UHPLC over HPLC - how does it keep your food safe
  • What type of equipment is needed to take advantage of UHPLC?
  • Practical applications of the UHPLC for food analysis

Hammack is an Environmental Manager with the Florida Department of Agriculture, Division of Food Safety, Chemical Residue Laboratory.
