I currently have an Agilent 1200 series LC. I have $2000 and I need to spend them quickly on hardware to upgrade the system. I am looking for advice on what would be some good components to consider. My main focus is on detecting trace amounts of wax molecules in plant cuticle wax samples. This means very long-chain alcohols, acids, ketones, esters, etc.

I have a Quaternary Pump, Isocratic Pump, Degasser, Autoinjector, Fraction Collector, DA Detector, Fluorescence Detector, Heated Column Unit, and a 6120 MSD with an ESI source.

Any suggestions are greatly appreciated!
