Hi
As additional comments
1. I used to favour, for economy, buying the 1000ppm standard and then diluting to my required level for standard addition analysis. The diluted standard I would then store in screw cap septum sealed 2ml autosampler vials in the freezer.
2. Ensure that your column/detector can resolve EO from acetaldehyde. which can give a false positive.
