In the USA, Masters level chemists are in demand. I have the feeling that you are outside of the States, is that correct?
Have you considered taking a position with a temporary scientific employment company? Firms like Kelly Scientific and others have positions they fill for their clients that are temporary, but they are often extended to be permanent. In other words, they use the "try him/her, you'll like her/him" approach. The employer gets to put you on a 90 day contract doing LC-MS work and you get that experience, which you can either use to move on to another role or you get to go "perm" with that company.
“Humility is not my forte, and whenever I dwell for any length of time on my shortcomings, they gradually begin to seem mild, harmless, rather engaging little things; not at all like the glaring defects in other people’s characters.” - Margaret Halsey
