ChE Faculty, Staff and Students, Effective immediately, all containers used for collecting HPLC waste must have a sealed cap. It is no longer acceptable to seal the container with parafilm or aluminum foil. REM has developed a useful web page that describes this new requirement and offers acceptable alternatives: http://www.purdue.edu/rem/hmm/hplcwaste.htm. For assistance please contact me or Adam Krajicek in REM. We will inspecting the ChE labs later this fall to ensure we are now in compliance. Thank you. Linda Linda S.
