mers of 2-PP, 3-phenylphenol (3-PP) and 4-phenylphenol (4-PP), and no me-thod has been reported for assay of 3-PP or 4-PP. While the previous method employing HPLC-UV after derivatization with 4-fluoro-7-nitro-2,1,3,-benzox- adiazole was simple, the reagent is expensive and the system was not applicable
Waters also offers a selection of glass sample vials and plastic sample vials that fit most manufacturers’ instruments. Two of the most popular uses are as HPLC vials and GC vials. These chromatography vials can be used as sample storage vials by adding a solid caps with liner.
When in use, I only use 0.5uL for each sample (usually no more than 20 samples), so there is a lot of reagent waste. I looked for a similarly small-volume insert or vial to minimize the
