How did you proceed, which system did you use? Somebody use the LADI trawler or are there better alternatives?

We want to determine and monitor how much microplasty is in our local lakes.

I am grateful for all the tips and experiences you share with me.

I can help with analyzing microscopic plastic particles, but not microplastics. Let's start with most expensive and go to least expensive.

For R&D, we used a liquid nitrogen cooled microscope FTIR with ATR accessory. The ATR might not be needed. It did pretty well, although black samples could give problems. Cost, with libraries, was about $100 k. It would easily handle particles smaller than 5 mm.

You might be able to get by with a standard diamond cell FTIR. These are much less expensive, but still would run in the tens of thousands of dollars. The 5 mm range particle size is something you would want to try before buying.

Polarized light microscopy is another techique. Less expensive, but it takes a fair amount of operator expertese. Don't know if it works on all plastics.

This will give you some places to start investigating. Please come back with any questions.
