WebThe 19F NMR chemical shifts span a range of ca.800 ppm. For organofluorine compounds the range is narrower, being ca.-50 to -70 ppm (for CF3groups) to -200 to -220 ppm (for CH2F groups). The very wide spectral range can cause problems in recording spectra, such as poor data resolution and inaccurate integration. WebParts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water. The quantity "1 ppm" …
WebWith the assumption we’re talking about, then it’s not just 10 mg L -1 but it’s also 10 mg kg -1 . You’ll see that 10 mg kg -1 is w/w%. Both the grams cancel to give what is essentially m k -1 which is 10 -3 / 10 3 = 10 -6 = 1/10 6 = ppm. Ok, thanks for your help ! :) Let's assume that the ppm is also by weight.
