Can the PTK be saved and used for decrypting subsequent captures?

Can the PTK, from the WPA handshake (or handshake packets), be saved and used for decoding subsequent captures? In other words, when raw 802.11 packets are being captured to a ring buffer, if the handshake is saved from a buffer, can it be used to decrypt the other buffers in the ring?
