How are SPMDs and POCIS shipped?
UNEXPOSED: SPMDs on the EST carriers (for use with EST deployment canisters) are shipped in hexane-rinsed, gallon-sized tin cans, similar to paint cans, under argon gas. The gallon sized can will hold up to 3 carriers, and can be stored in ambient air for a week or more. For longer storage time the cans should be frozen at – 20.0°C; at this temperature they will keep indefinitely. Trip blanks will be shipped in hexane rinsed tin cans under argon gas. Can size will vary with the number of SPMDs in the trip blank. POCIS on carriers (for use with EST deployment canisters) are shipped in methanol rinsed gallon-sized tin cans with a spacer to keep the carrier stable during shipping. The lids of the can are secured with metal clips that will require a screw driver (or similar tool) to remove. Loose POCIS are shipped threaded onto two carriage bolts and secured with self locking nuts to keep the POCIS stable. These are placed in methanol rinsed gallon-sized tin cans under argon gas and the li
