I have really been wanting to create a YouTube channel that tests products for phthalates. To actually test for them yourself you need a Gas Chromatography-Mass Spectrometer. These machines cost >50k though so it’s prohibitively expensive.
Not easily no. LC-UV could be a solution if you have good standards. Sample prep depending on how you do it can run in the tens of dollars per sample be it for GC or LC.
It is not just about throwing a sample in a machine, you need to make calibration curves, and take matrix effects into account etc... Not a trivial problem and pretty time consuming.
There are several companies that do mass spec for the pharmaceutical industry, running large numbers of samples for drug discovery, clinical trials, etc. I'm not sure how much they cost but you might be able to work out a relatively cheap price per sample if you do all the sample prep yourself before sending it to them. Maybe they'd want the promotion.
Are there any cheaper ways to do spectroscopy?
