We have a mid size property where we are going to undertake a soil remediation project over the next few years. We want to take about one hundred samples before and after the three plant and terminate cycles we have planned. Getting the samples done through the university would be prohibitively expensive. I have a background in analytical chemistry and want to know if anyone has recommended brands for testing equipment like spectrographs and colorimeters. I found some stuff on Ali express I don’t know if I trust it.
Any advice is appreciated.

Edit to add what we are testing:

Nitrogen, Phosphorus, Potassium, salinity, trace heavy metals, Ph, Organic Matter, calcium, magnesium, chlorides, and sulfur.
