Description:Aldehydes and Ketones

Method for the analysis of aldehydes and ketones that have been collected in DNPH sorbent cartridges. The DNPH solution forms a hydrazone derivative with the target compounds. The cartridges are extracted with acetonitrile and are analyzed by reverse phase high-pressure liquid chromatography (HPLC) using UV detection. The cartridges are available in a diffusion sampler package. There is also a TO-5 method which uses impingers with DNPH solution instead of the cartridges. The cartridges are much simpler and easier to use. Some scientists feel that high levels of ozone may negatively impact analytical results, so an ozone scrubber can be used if their project requires their use.
