Gas chromatography isn’t used for analyzing metals in dust wipes because it’s built to separate and quantify volatile organic compounds, not to measure elemental metals. When testing dust wipes for lead, labs digest the sample to dissolve metals and then quantify lead with metal-specific techniques like Atomic Absorption Spectrometry, Atomic Emission Spectrometry, or Anodic Stripping Voltammetry. These methods detect lead atoms or ions directly, even at very low levels. GC would require converting metals into volatile forms or coupling to a very specialized detector, which isn’t standard practice for this purpose. That’s why GC isn’t listed as a method for lab analysis of dust wipes. The other methods are appropriate because they are designed to measure metals in solution or as ions, matching the goal of determining lead content.
