Experience has shown that deionized water, specifically from a website new demineralizer with new resin, usually has substantial quantities of organic and natural matter, that is produced intermittently and it is undetectable which has a conductivity h2o purity gauge.
The flask (containing the extracted O&G) is reweighed. The original fat from the flask is subtracted and the overall O&G excess weight in mg is calculated. The outcome offer the O&G focus in mg/L.
