LIGO Document E0900479-v3
- Instructions for taking Low Volatility Residue (LVR) Wipe Samples
- v3: Updated with 3M 8247 being added back in as was removed by mistake in move to "voluntary" respirator use.
v3: posted by CTorrie for CTaylor. v3 includes updated clarification on respirator use.
v3: 8/29/2019: File added. K. Baric added FTIL instructions provided by JPL in August 2019 as reference. These used by seen as additional guidance in line with LIGO guidance.
v2: Updated to include use of Hexanes, which results in additional safety precautions.
v1: This procedure is a revision from the procedure provided to us by Mark Anderson of JPL. It makes a distinction between sampling holes and surface areas. It also cites the JPL recommended surface area as a minimum and provides minimum and maximum surface sample areas by allowing re-dipping of the wipe into the solvent.
