CHEM-5181

• This course WILL be offered in Fall 2011, WILL NOT be offered in Fall 2012, and will likely be offered again in Fall 2013
• This is the new home for the CU-Boulder Graduate Course CHEM-5181: Mass Spectrometry and Chromatography. A shortcut to this page is http://tinyurl.com/CHEM-5181.

• The old web page is located here, and I'll be gradually move things over to this Wiki page, which is much easier to update.

FAQs about CHEM-5181

• Can I audit the class?
  • Answer: Yes, but you need to register for it as "Audit / No Credit", either as a regular CU student or through the ACCESS Program. Auditors typically attend lectures but do not do the labs, homeworks, or exams, unless they want to.

• But I don't want to register at all. Can I still audit the class?
  • Answer: No.

• I work in industry and use MS and chromatography in my work, can I take the class?
  • Answer: Yes, registering through the ACCESS Program. You will have the option to take the class as "for grade", "Pass/Fail", and "Audit / No Credit." In making the choice, some things to think about are: (a) you need to have the relevant background or be willing to work to gain the background, especially if you want to take the class for credit. (b) This is a class for 1st year graduate students in Anaytical & Environmental Chemistry, and it takes quite a bit of work to take the class for credit. If you don't have much time for the class due to your work responsibilities, you should register as "Audit / No Credit".

• Do I need a background in computer programming or on Igor to take the class?
  • Answer: No. We cover those topics but we assume that people have no background when they start the class. We strongly recommend donwloading a demo version of Igor and going through the Getting Started section of the manual and the Video tutorials before the class starts.
