The knowledge you don’t already have that is needed to maintain computer systems in organizations someone with your background should be able to learn on his own from books and experience. If you want an M.S., there are scores of online M.S. IT programs that, it seems from my surfing the web on it, will accept you as you are. I suggest exploring that - sign up with them for information and ask them if they will accept you as you are. The bricks-and-mortar colleges don’t seem to be as open in accepting people for M.S. in IT without a B.S. in it, although I see that the Cal State LA M.S. program admission doesn’t mention an undergraduate degree, but does mention working experience.
There’s a lot to be said for touching base with the “real world” now by working in industry or at least applying for jobs to see the response.
No doubt there is some kind of IT job you can do as you are.
Computer Support Specialist
From http://www.bls.gov/ooh/Computer-and-Information-Technology/Computer-support-specialists.htm#tab-4:
“Education requirements for computer support specialists vary. Computer user support specialist jobs require some computer knowledge, but not necessarily a postsecondary degree. Applicants who have taken some computer-related classes are often qualified.”
There is this interesting passage at http://www.wetfeet.com/articles/career-overview-information-technology:
‘Requirements:
There’s a broad range of jobs in IT, and not all positions require technical skills. “The best tech support people we had,” one insider says, “had humanities backgrounds.” Technical, communication, and business skills are all important to the field, and four-year college degree programs-not necessarily in computer science-are still one of the best ways to prepare for entering the IT job market.’
But you may want to do something more ambitious.
For instance:
Computer Systems Analyst
The Bureau of Labor Statistics (BLS) expects 24% job growth and 200,000 job openings in this job between 2012 and 2022, which makes it exceptionally hot.
From http://www.bls.gov/ooh/computer-and-information-technology/computer-systems-analysts.htm and http://www.bls.gov/ooh/computer-and-information-technology/computer-systems-analysts.htm#tab-4:
“Computer systems analysts study an organization’s current computer systems and procedures and design information systems solutions to help the organization operate more efficiently and effectively.
“Most computer systems analysts have a bachelor’s degree in a computer-related field. Because these analysts also are heavily involved in the business side of a company, it may be helpful to take business courses or major in management information systems.
“Some employers prefer applicants who have a master’s degree in business administration (MBA) with a concentration in information systems. For more technically complex jobs, a master’s degree in computer science may be more appropriate.
“Although many computer systems analysts have technical degrees, such a degree is not always a requirement. Many analysts have liberal arts degrees and have gained programming or technical expertise elsewhere.”
A really plum job is Computer and Information Systems Manager. Such a person is in a position of leadership and the pay reflects it.
From http://www.bls.gov/ooh/management/computer-and-information-systems-managers.htm#tab-4:
“Computer and information systems managers normally must have a bachelor’s degree in a computer- or information science–related field. Such a degree usually takes 4 years to complete and includes courses in computer programming, software development, and mathematics. Management information systems (MIS) programs usually include business classes as well as computer-related ones.
“Many organizations require their computer and information systems managers to have a graduate degree as well. A master of business administration (MBA) is common and takes 2 years beyond the undergraduate level to complete. Many people pursuing an MBA take classes while working, an option that can increase the time required to complete that degree.”

Should you want to pursue employment in chemistry, what will really get you in is hands-on experience with gas chromatographs, GCMS, HPLC, and ICP-MS (but it is hard to get that experience at most universities).
There is also a field developing in computational - or data - science in which I find a bricks-and-mortar school that will accept a chemistry B.S. for its M.S. program (Georgia Tech, there may be many others) and quite a few jobs coming up on an Indeed.com search. Scientific programming languages (especially C/C++ and Python) are called for. An area where chemistry and IT come together is in LIMS (Laboratory Information Management Systems).
