This question was asked by @mimiss during this week's Open Hour.
The bucket monitor is used to sample chemicals in the air including VOCs (volatile organic compounds) and sulfur compounds. Buckets are similar to Summa canisters, which capture 30-hour samples in a polished container. Summa canisters come with a 2um filter that is built into the flow controller to prevent contamination of the intake valve. This is a two-part question:
- Can this be added to the bucket valve?
- Can the filter be analyzed independently to get a snapshot of particulate matter?
