The active ingredient in Roundup Weed and Grass Killer is glyphosate, a chemical known as N-(phosphonomethyl)glycine, which is present in the form of its isopropylamine salt on the Roundup label. This form makes glyphosate easier to handle and more effective. Regular Roundup contains 2 % glyphosate, and it must be further diluted with water before use.
In this experiment, Avantes tested these low concentrations of glyphosate with a particular variable path length dip probe with a narrow tip to assess the chemical’s absorbance. Two dip probes were used, one with a path length of 10 mm and another with a path length of 5 mm, to assess the detection limit for the lower concentrations.
As detection limits in an absorbance measurement are inversely correlated with path length, Avantes anticipated that the 10 mm path length would provide more precise and dependable results. The 5 mm path length was also tested to investigate whether the shorter path length would still detect the glyphosate and if its results would be comparable to the 10mm path length.
*The narrow tip variable path length dip probe is only available from Avantes North America. Avantes HQ provides a full range of transmission dip probes with fixed or variable path lengths.
