| |  | All pieces stored in N2 cabinet |
| |  | Band sawed in 1993 for consortium |
 | Past Processing (1994-1996) |
| |  | Sealed and stored in N2 cabinet |
| |  | Special handling for organic analyses |
| |  | Large and small pieces processed on flow bench |
 | Current Processing of ALH84001 |
| |  | Large pieces processed only in cabinet |
| |  | Small pieces processed on flow bench, sealed in cabinet |
| |  | Special handling for organic analyses |
 | Current Achondrite Processing |
| |  | Process large & small pieces on flow bench |
| |  | Seal & store in N2 cabinet |

| Possible Sources of Organic Contamination in MPL |
 | Xylan lubricant - removed in 1990 |
 | Sample containers - vials and nylon bags |
 | Cleaning procedures - ultrapure water, alchohol wipes |
 | Gloves - neoprene and ployethylene |
 | Proximity to humans at flow bench |
|
|
| Steps to Avoid Organic Contamination |
 | Designate cabinet for martian meteorites only and do special cleaning |
 | Test all sources of organic contamination (several are in-work) |
 | Prepare samples for organic analyses without plastics |
